It's been a long time since I last upgraded my countersink bits. It's just one of those things that always worked well enough, and the screws usually get hidden anyway. Lately I had a few woodworking projects with exposed counter-sunk screws, and I decided it was time to upgrade again.
These are the two main countersinks used in the video:
IRWIN Tools Black Oxide Countersink Drill Bit, 5-Piece Set

If you're going to buy new bits then obviously try out the ones he recommends. But if you want to keep your old bits and get 'clean' holes then run your countersink bit in reverse real quick. Cleans up the hole without digging out anymore wood.

@Don-cs7fe 3 года назад

The countersink with the hole is a Weldon style that I used on most metals when I worked as a machinist. They work well on wood especially the harder stuff. When working on harder metal we used combination center drills often with the pilot portion shortened & modified to 135 degree point. Also 90 or 82 degree spot drills especially Guhring brand work well on all materials for countersinking & close tolerance hole location.

@felixf5211 3 года назад

I work with steel and mostly use Weldon. Zero flute countersinks work best for me.

@theOrigKevinDoe 2 года назад

When using countersinks, you should slow the RPM of your hand drill, or drill press way down. High speed countersinking is a recipe for chatter.

@aries6776 2 года назад

I've been told this. I've got both types of countersink bits. I'm going to try it now with my drill press set really low. EDIT: set as low as it would go, with a pre-drilled hole chatter on the fluted bit but no chatter with the zero flute design.

@lv_woodturner3899 2 года назад

I have the cross cut countersink which I also purchased from Lee Valley. Excellent countersink. I like to use countersinks in a brace. I get more control of depth of cut by hand cranking the brace. The multi-flute style of countersink gives a better cut for me with no chatter when being hand turned in the brace. Dave.

@joelaw 3 года назад

Just a quick note on those combination drill/countersink bits: if they are the DeWalts, there should be a little Allen key adjustment on the side to shorten/lengthen how much of the bit is exposed. This will enable you to make shorter pre-drill depths. That said, I’m going to check out those Lee Valley bits. Thanks for another great video.

@bullfrogpondshop3179 9 месяцев назад

I agree with all your points. Irwin style are designed for metal, just like typical twist drill bits. Don't use lee valley style on metal of any type. I'll add this regarding the "lee valley" style: Apply medium firm downward pressure when starting the cut, otherwise the countersink can end up off-center with the drilled hole. I think the off center countersink is a result of having only one cutting surface; the bit doesn't automatically center itself in the hole the way the Irwin style does.

@CALDues Год назад

I machine mild steel and tool steel at work and the countersinks we have available to us are carbide versions of the Irwins you have. We have to spin them at usually the slowest RPM to keep the chatter out. We also have to watch the chipload or risk blowing them up. Speeds and feeds. If running in reverse works I would think eventually they'd be well polished, bite less and then work with forward rotation. Twice the life? Thanks for another great video.

@cspann2872 2 года назад

Good info Thanks! I have a single flute bit from my days at a boatyard. I have no idea where it came from but I still use it and touch it up with a diamond hone. It works well in metal plastic and wood, whereas the multi flute bits would leave chatter in all materials. It got me t thinking - if the flutes were staggered unevenly so that they couldn't fall into a valley formed by the flute before it. There would be no "resonance" because the oddly positioned flutes wouldn.t allow hills or valleys to begin to form. I wonder of anyone has tried that?

I have used the single flute style counter sink on wood, aluminum, brass and mild steel it worked fine. I didn’t notice any issues with the cutter after using on these materials.

@TheSnekkerShow 3 года назад

I haven't really had any trouble with my five-flute ones either. Good steel should be able to take a little abuse, especially if slower speeds are used for cutting harder materials.

@minimonkaloyd 3 года назад

If I'm not mistaken, you can't over-drill with the zero-flute countersinks. Self determined by when the cutting edge passes the surface. The different sizes allow for differing screw head sizes (#6, 8, 10 etc) with consistent results every time.

@LBCAndrew Год назад

Those new ones with the angled hole work fine on metal as long as there is a hole drilled. I have used mine for aluminum, copper, brass, low carbon steel, stainless, and even high carbon (annealed obviously)

@ngandong1 3 года назад

I think people should learn how "direction" works in woodworking, in this case, reverse drilling. Starting with a few pulses of reverse drilling will give you a better result than going straight with normal drilling, given any drill bit. Pretty much everything in woodworking the end result will be depended on how well you understand direction works.

@djnugz2511 3 года назад

They're called flutes. Different countersinks for different applications

@timeconstrained2400 Год назад

as a general question - how do I know whether I'm buying a wood or metal countersink? how do they differ in design. What do I look for in the store. Like a lot of DIY stuff it seems most is trial and error with very few instructions available.

@TheSnekkerShow Год назад

Most countersinks you'll find in the store are intended for use with wood, metal, or plastic, and it will usually say that on the packaging. You're right though, finding the one that's best suited for a specific material seems to be more challenging. Good saw blades normally explain that on the packaging or website, but not everything.

@jimwiskus8862 Год назад

You might try a catalog for machine shops or even swing by a local machine shop to see what they recommend for a countersink for metal. Grainger’s or MSC might be a good place to start.

I just tried it on a piece of PVC and it worked well, but you have to pull out while the bit is still moving to avoid leaving a shaving connected at the end. The fluted bit was a little rougher, but still adequate.

Flute countersinks chatter because they are blunt, ( even if they are straight out of the packet ) and are also dependent on the speed of cut

@aries6776 2 года назад

I think he covered it with his point about the different material conditions present in wood. I've had good results with the fluted bits in metal and not wood but now I know why. Metal is an isotropic material, wood definitely isn't.

@boots7859 9 месяцев назад

You can put a chamfer on an edge, and your screw can still be above the surface. If you are countersinking, you are chamfering the edge, but you are also widening it enough for the screw/bolt to be flush or lower than the surface.

@bc1014 2 года назад

I'm a newbie to woodworking so was practicing my 'learn before buy' rule re countersinking. Came across vid by an old American Co on this topic, don't know if info is reliable as they sell tools after all.. . It showed countersink angle different for metric vs imperial for how much contact the screw-head makes as it could work itself out if not seated properly? and that in general more flutes better for hard materials while none/less flutes are for softer? and the countersinks with one or no flutes at all are best used in a machine bcuz they're eccentric with only one cutting edge. . . can any of you experienced folks confirm if true? thanks on behalf of 'newbies'!

@TheSnekkerShow 2 года назад

I have found that the zero-flute countersinks tend to get off-centered on harder materials, like acrylic, when drilling freehand. I haven't noticed it in wood yet, at least not enough to catch my attention.

Couldn’t the tear-out be just due to dull or old bits…

@TheSnekkerShow Год назад

I don't do enough countersinking for my bits to get dull.

@whats-the-tea-thomas 8 месяцев назад

I have recently discovered that any cutting edge (countersink, router bits, saw blades, etc) I’ve used on pine boards in the past, when inspected closely, has a build up of sap/resin on it. Taking the time to clean that buildup off has restored what I thought was a dull edge back to like new quality. I’m not saying this is the case in this video but if a cutting edge made of a hardened metal seems dull from cutting wood - it’s probably not actually dull - give it a good cleaning (I like hot water, dish soap, and a stiff bristle brush - oil after if needed to prevent rust) and try again before you buy a replacement.

@whats-the-tea-thomas 8 месяцев назад

This especially applies to tear out from a circular or miter saw blade. The tips of those blades get hot from friction and they get such a uniform coating of sap after repeated use that you can hardly see how dirty the blade actually is.
