How to choose the right tool holder for your CNC Machine | DN Solutions 

Barry you are the BOSS! Those hands? The strongest roughing tools out there! That body? The most rigid and completely indestructible mass of sheer power with no competition! No machine can match you!

Great video Barry! The average machine operator is only trained to pick up any holder the tool fits. I only started to learn this information as I encountered problems and/or when outside service representatives had to be called in, some came with a machining background. My advice to all machinists, make friends with field service technicians and applications engineers who service your machine tools. They will teach you things most won't. That's how I know much of what I do outside of general machine operation.

One other thing to note: HSK gets clamped on the inside while BT and SK get clamped from the outside on the stud. Because of the centrifugal forces at high RPMs the clamping force gets weaker on BT and SK while it gets stronger on HSK holders. This is something to keep in mind for really fast spinning spindles (like 30k and more)

Weight is not the ONLY reason you can run HSK or Capto faster than a traditional milling machine taper. The drawbar is a HUGE difference. To put it as simply as possible 30/40/50 taper tools "OD clamp" the pullstud so the faster you rotate the less clamping force you have. HSK on the other hand "ID clamps the toolholder" faster = greater clamping force

Wow! What a great idea, I never seen anybody do such a comprehensive introduction/explanation of the the things machinist use every day. Great job Barry!

"So you want to be machinist huh" yea "there is a chance you've been doing this all wrong" yea probably

Great reassurance. I came to an aerospace MRO company using some off brand Korean tools and I’ve been slowly incorporating some high end kennametal tools. So far I’ve been able to prove the efficacy of the cutters and the hydro force holders, so the next step is a huge order of hydraulic and hydro force chucks !

Clean work depends 50 percent on the right tools and 50 percent on the skill of the machinist 👷‍♂️ Great work Mr. Barry I hope to see more and more of these videos in the future but next time we want to see Mr. Titan here man we miss him so much BOOM 💥

A tip with collet is to get it snug then spin the tool as you tighten. Helps with runout

Great video. As someone in the business of selling these I think you hit on almost everything we teach in an entire day of training in 10 mins 👍

Great instructional video, extremely well done and thorough. For someone that's been around it's easy to pick up. For people that are new, I wish you had broken down your rating system and explained what each rank was actually measuring (TIR, Dampening, torque, etc)

Lot of great information. Learn something new everyday. Much love and gratitude

This is what you call a knowledge bomb.

great information for the industry, Thank you Barry for always helping. Your one of the anchors in the manufacturing industry, hold it down baybeee!

Finally a video on tool holders! :D Great work, if you don't mid a part two (or more) and getting into more details would be so awesome! Great work as always!

Cant wait for the vídeo about the other holder that you refered... Im learning from watching your vídeos! Thank you 🙏

Zero mention of capto tooling which I found interesting.

My Bridgeport uses R8 collets

Machining just got a lot more complicated. LOL Love it.

I like watching these videos then going to work and using an old manual mill from the 80s

Main benefit of HSK is the drawbar opens up inside rather than clamping the outside of the pullstud. So faster RPM clamps it harder rather than letting go. Some downsides like harder to keep clean and expensive Pick the right machine for your job👍

Everything I knew about machining was wrong. I didn't know anything correctly before I watched this video. Now, I know a little bit about machining. Thanks.

REGO-FIX powRGrip holders are great too. Just about every machine tool manufacturer at IMTS was using these holders while showcasing their machines.

Great knowledge sharing. Been struggling to understand this things at the beginning of my career 14 yrs ago in complex composites machining with 5 axis CNC (HSK63A). Lots of try and error to reach today performance. This video helps a lot in transmitting knowledge to new machinists. Thx so much!! From Aerospace Composites Malaysia

Super cool vid!! I try to use 100% shrink fit, cus I do small work and will be buying a robo with a 5th axis soon. They are so simple to use and stay clean and have great runout.

This is super informative and should be shown to all new (and old) machinists

One thing that gets over looked with cat/bt holders is the pullstud. Specifically the torque used to attach them to the holder. Most of the time the specified value is too high. What happens is the small end of the holder buldges slightly. That interferes with how the holder fits in the taper of the spindle. This over time shows up a wear pattern at the small end and at the flange end of the holder. What's actually happening is that since the holder is not making contact through out the taper it ends up like the clapper in a bell. This is why they seem to have such bad runout. A properly fitted pullstud that doesn't buldge the holder will make the holder contact the full lenght of the taper and will run much truer. Take a look at the cat/bt holders in most shops and you're likely to see the tell tale wear pattern of over tightened pull studs.

Great info and very helpful for beginner. Keep it up. Boooomm

in the uk re dont have cat40/cat50, we use metric version bt40/bt50

Awesome information to share Barry! Great paced video, with lots of great information! Good Job!

Excellent video Barry!! Tons of great info here. I just want to say that if you make parts out of fairy dust you don’t need any of those tools! 😆 great work dude!

Hydraulic holders are my favorite too! You should try the original HYDRO-GRIP from the Swedish company ETP that for 20 years used to OEM for Sandvik Coromant but have their own distribution last 10 years. They have unique technology and products being “maintenance-free”👍🇸🇪🌱

I'm moving to shrink fit

Saludos desde Guadalajara Jal, Mex me gustan sus consejos y me alientan a ser mejor en mi trabajo

Hi Barry. I love this holders

In China, we use ER holders at the most of time, side lock holders is rare.

Very informative video.I am machinist for 18 years one of main problems i saw in different shop holding flatness of part within 0.0001.Can you make a video about that?

Outstanding video!

Haven’t seen the safe lock TE end mills yet but I have 6 new shrink fit safe lock holders waiting on them. As a side note though I have not personally seen it I have heard of a safe lock coming out of a hydraulic holder. I can’t see how it is possibles but one of the Kennametal guys was telling me about it. Thanks for the videos!

Gone the days of the fly cutter, that is what we called them in the UK. I know a guy that got his hand ripped up badly with one on a manual mill, and they wreck your bearings.

What are your thoughts on the "Capto" style adaptors?

Great summary, thanks Barry!

Nice Video but don't forget there are some classifications for the ER Collets as well. Some are more accurate and they also have them with Vibration Dampeners and coolant Holes.

Capto holders are the best!

Ur sample cat 50 shown in vid doesn’t appear to be dual contact

Thankyou this was very informative information

These are the best tool holders. And we sell them in our shop. Equivalent to the typical “I’ve actually got one of these myself actually”.

love from italy, you guys are amazing. Would love to do a visit at workshop. booooooommmmmmmm like titan say

Love this video, can we see a video on how to improve efficiency when machining, we have a young group of toolmakers at our shop with experience of 2 years all the way up to 15-20 years but need to find better ways of running our programs over night and tips and tricks to ensure we are getting full use of the machines to keep management happy and to reduce hours on quoted jobs for making mould tools. Love this channel and the content it provides.

Very informative and interesting content! keep up the content, here is another quite fresh machinist from Finland. Something i would like to see from you guys would be reaction videos to those "rural machining" :D videos from India or who knows from where!

Really great tooling tutorial 👏👏

You can have dual contact Cat 40 and that BT30 you had in your had is a dual contact Big Plus holder.

Great sir 👍

Awesome editing!

Nice video. Good job.

Thank you for this video.

Have you guys ever worked with SECO capto holders? Or any other polygon holders for that matter. Great video, I'm currently working on two machines, one HSK63 and one CAT50, i do like the HSK more because they're lighter and still pretty rigid. Good thing we use both depending on the job. Also, Albrecht holders are also very easy to use and have very good runout and strength. Kind of like an hydraulic force holder, just that the collet is drawn into the conic hole by a thread. Very interchangeable and versatile tools

Good information !

Top work Barry!

capto beats them all and i've seen HSK up to 180 on a 250kw machine

Good tips 👍.

Shouldve mentioned something about collets having a tool life as well. something i didnt know until not that long ago

I prefer APC for accuracy.

It ist right that HSK holders can run faster than steep taper tool holder. But it is not due to their lower mass. It is because the clamping force gets higher wit the rpm and not lower like it is the case with steep taper holders.

i don't see any R8 holders in there 😆

That's a pretty cool presentation Mr. Barry. I have a few questions? Have you had shrink fit holders pull out on you? Every time I have had a roughing path which had a section with too much radial engagement the endmill would pull out an 1/8" and pop it like it's not so hot. I have used them with limited radial engagement dynamic tool paths with no issues and it gave me good clearance for that job. I like the shrink fit extensions for clearance on some 5 axis transformations more than the ER extensions. How tight do you need to tighten hydraulic holders and mill chucks. I'm guilty of the put a cheater on it and be sure its tight, extra tight. I've seen little torque wrenches for hydraulic holders but I don't trust them. Just an aside for sharing my experience, I have never pulled a tool out of a mill chuck, but I have on a hydraulic, and once a hydraulic holder pulls out it will do it again in my experience. So off to the recycling gods she goes. How in the hell do you tune those devibe arbor holders? The DMU 90P that I run the most had vibration sensing but I have never seen any instructions when I opened up the holders on how to tune them. Is there a SOP for tuning them? I've asked a few people and I really didn't get much of an answer. With that hydro force holder with the safe lock collet do you have to use a specific endmill brand or can you grind it yourself on a T&C grinder?

Hahha, full slot that sub button... hahahaha :D

we use the HSK100 holders with a coolant tube on the inside. they are freaking crazy

Boom

♥

HSK is dope

Hi i have a question . Do you balance your tool holders and from what rpm you advice it . Thanks from the Netherland

We do not rough with ER collets. You'd be wise to do the same.

Something to note, after long enough use of shrink fit tool holders. After consistent reheats to put new tools in or tools breaking at the base of the shrinker. The runout gets worse and worse over time for the holder. Which can lead and cause tool breakages inside your parts

Fun fact, CAT40 and CAT50 both come with standard taper only as well as a plus series with dual contact.

Nice video but the music got annoying while he was trying to talk about the tooling

Alot of these tools are for a mill and i dont do much on them anymore i run more lathes nowadays.. but one thing ive always had trouble with is knowing when to use a free floating tap! Also alot of programers nowadays really enjoy 35 deg cutting inserts to rough alot of material instead of an 80 deg and this is common for alot of straight turns no angles or anything special.. why is it being used alot when 80deg are proven to work better and longer.. how do i convince my programmer to start cooperating it into the work??

There's a chance that some of those Haimer tool holders came through my hands 😎

My favourite spindle connection type is the chips that fall into the taper and get crushed up into the spindle during tool changes because the operator couldn't be bothered to clean their machine.

Haven't said anything about CAPTO holders man they are the Kings even at the smallest size

My mill has a BT30 taper, so I tend to pick BT30 toolholders

Dampening capability? That depends on whether it has through coolant capability. It's called DAMPING.

What would you recommend for making complete rotary engines?

What about RegoFix Power Grip Tool Holders? Thank you very much from DENATEK Spain.

Capto? Rego-fix? Emugee FCP holders? It would be nice if you guys were not so biased. Kenametal is good stuff, but they aren't the best at everything. I still enjoy your videos.

I would have wanted more information and a video twice as long😅

Barry, how much does the machine you're using play into toolholder selection? Oh...how good are the machines "Markforded" makes? In your "Thank you to our Partners" section, they seem to make the Metal X, X7 and Mark Two.

All my misconceptions about tool holders…. 💨 gone!

I don't know about you but I'm stuck with what they buy and that's the truth in most shop's , not shure what world your living in but it's not the world 90% of us live in .

Cat40 can be had dual contact too.

Anyone have input on Haimer's Heavy duty shrink chucks vs Hydraulic?

I have a quick question. I work for a company that does mass production of a part. I am trying to make a standard to judge if a tool holder is reusable. A lot of our tool holders have uneven wear to the taper. Is it still okay to use for mass production?

Have you seen those polygon tapered toolholders by sandvik? They would be cool to see demonstrated. Also, I have been trying to get my company to switch from ER collet holders to hydraulic or shrink, and they won’t. We are heart of the semiconductor anode industry and the money is there, we do everything the slow way, yet I can’t get them to listen about the benefits. Our feeds are sad, my department alone provides 70% of the entire worlds supply and we could increase Efficiency 500% with a couple small changes..

You gonna show me how to ballance a shell mill?... please?... I just started and it's taking so much down time....

Those little replaceable carbide chamfer cutters, our company send out for re-grind and puts them back into stores😂 so I’ve never trusted them, always q-set after a swap out 🤟

Hey have u ever used bilz holder

Hello. Why do you work in Mastercam and not in SolidCAM?

How does regofix stack up in this list?

Merhaba neden big plus bbt tutuculari incelemeye ve karsilastirmaya almadiniz ???

Interesting video on the surface. I have been in the industry for 20 some years and yet to see anything but CAT 40/50 spindles on machines. Shrink fit tool holders are for youtube channels because no shop wants to pay extra for a machine just to put tools in holders. If you have tight tolerances then its called playing with cutter allowances in the controller and a couple test cuts to see what size the cutter is cutting. I have used dampener style tools in the past with varying success. Hydrolock holders sound great but your locking yourself into a proprietary tooling ecosphere then. Bottom line is the vast majority of machine shops will never see return on cost for anything but regular old sidelock and ER collet holders. As for the video itself. Coincidence that most of the tooling talked about is also sold by Titans webshop? Video screams total add.
