Talk about how not to drill ! How could anyone tackle any job like this without first learning HOW to do the job ? he ruined both bits instantly because of drill speed .... It wasn't carbide vs HSS...It was man vs carbide an HSS !
The reason you came through at all was that the carbide can stand the heat better. You putted way to high rpm on the drill. If the drill dont cut at low rpm it is either to low preassure applied or the drill is not sharp. Higher rpm is not the solution. HSS drills can drill stainless almost as good as a carbide drill, but HSS is easier to ruin so carbide will work better if good cutting-data can not be used.
You are right regarding the speed, and the hand drill problem. Stainless steel is quiet difficult though. There are plenty different grades in HSS so its not enough to say HSS is not good enough. Depends. I never used carbide bit yet, i am might give a try one day.
The drilling ability is not much different with carbide or HSS, it is the tool-life that is the big differens and in most cases a carbide drill can withstand more heat so it can cut faster. I was working in a workshop before that was working mostly with stainless steel and we used HSS-drills for everything except in the CNC-machines. HSS is a bit easier to sharpen so they are more versatile to use in hand-tools. If the drill is feeded with 0,025mm/turn (approx. 25% of recommended feedrate for many HSS-drills) it means that it takes 160 turns to make hole in a 4mm plate. If it takes more, like 500-1000 turns or so, the drill is not drilling but rubbing and thats what kills it fast.
@@sniffswe9416 "The drilling ability is not much different with carbide or HSS" I think you are wrong here. HSS is only meant to be used on plastics, wood and some softer metals, imo for stainless steel you need at least TiN coated HSS bit or HSS bit with at least 5% cobalt... the only way you will make a hole on a THIN sheet of stainless steel with a bare HSS bit is by pushing on it like a mule and on max rpm's
great demonstration friend , glad to see the bit stood up to extreme torture, no pussy test here my friends , so if this video hurt your vagina just chill , this guy talked me into buying carbide bits , any thing that can handle that is worth the extra $14
you cant even use carbide bits in most drill presses as they lack the rigidity to use them correctly.. i cant even use them in my milling machine even thought i use carbide end mills.
@@Migman2020 I wonder why that is since the endmill experiences radial forces while the drill experiences only axial forces so you would expect that if carbide endmills could be used then carbide drills could be too.
Thank you, great demonstration. Was gonna buy HSS bits but not now. Great video no music got exactly what i clicked on. I like how you waited to say it was 1/4" SS till the end
For drilling stainless steel (304, 316) HSco is good enough. The HSS drill he's using is probably just shitty quality, plus his speed seem a bit high. The trick is applying enough pressure; once you get the cut going you'll zoom through.
Your analogy is great! Watched this video again and it looks like he's making fire and putting out with water. No drill is a match for this man. Thanks for the tip Le... Have ta Google (304, 316) HSco
i drilled a stainless turbo adaptor with hss,at least 10 holes,10mm,with champhers to seat heads,hidden,15mm champher,3 stage to get angle as working with what i have,used light oil,very slow revs,very sharp drills.no probs.,u want to learn about drills,[& tools]punch in BOLTR aVe.canadian guy,god.
ww2 colorizer If you have worked with drill bits, you will learn that running them fast, they will overheat... and get dull. You learn this in one of two ways 1. The easy way: You read, watch videos, others tell you etc. 2. The hard way: You will run your bits too fast, and they will get dull. What purpose do you think the oil being applied serves? Even at lower RPMS, the drill bits will overheat. Spinning the bits at high RPMs and applying oil is similar to drinking diet soda while eating many plates of food at a buffet. It DEFEATS the purpose!
@@billt7283 YOUR DRILL PROBLY ONLY TURNS 200 RPM ! YOU JUST DIDN'T KNOW ! IF YOU GET A NEW DRILL THAT TURNS OVER 200 RPMS YOU WILL RUIN EVERY DRILL BIT YOU USE AN NEVER GET ONE HOLE DRILLED !
A good HSS drill bit (like Walter) cut 5x time faster than what you demonstrate with your carbide drill. One tip,you want to drill faster? slow down your speed a lot, and no fear to put pressure on it.
i call bs. ive used hss bits high end and low end. they are ok for thin mild steel. but dull when cutting anything harder. drill holes in 1095 or 1075 then get back to me
Your drill is spinning too fast. You’d have better results if the drill was spinning at around 400 rpms. You’re getting too much friction with the drill spinning that fast.
TCT drill bits are used for masonry drilling through granite, and also for locksmiths drilling through hardened steel. I use locksmiths TCT drill bits to drill through tempered spring steel for knife making.
Ebay, search for "TCT locksmith drill bits" there are 2 types, masonry TCT bits and locksmiths TCT bits, you want the locksmith bits with sharp tips, not the masonry bits with rounder tips. The Locksmith TCT bits also don't require a center punch to make the initial drill hole, they just eat right intot he metal. Hope this helps.
Doesn't matter if it's in a hand drill or drill press, what matters is drilling slowly and constantly stopping to cool the bit off every 5-10 seconds. These drill bits were designed to be used in hand drills because they are locksmiths drill bits. Locksmiths don't carry around a drill press to drill through peoples doors and safes, in fact you can't use a drill press to do this job, you have to use a hand drill there is no other option for a locksmith. That's why these bits are known as locksmiths drill bits. He is just going too fast I have a demo video of how to drill through tempered spring steel with a hand drill and TCT bits if you want to see how to do it properly.
