I am a fan of Milwaukee products. This item meets the Milwaukee standard and performs well. I would buy this again. You should also try Milwaukee Power tools, they are some of the best.

This produces a professional finish! Get the size that matches the screws you will be using, so use this #10 countersink for #10 size screws.Instead of pre-drilling and then also using a countersink to make room for the screwhead, do both in a single action. It makes a perfect size countersink for the screw.The drill bit is also tapered, leaving a hold that the screw can grip onto along its whole length. It allows you to adjust the depth of the tapered drill bit by sliding the countersink part down the drill bit and tightening it in place. Adjusting this needs a ⅛” allen wrench (not provided). The adjustment is solid and there are tightening grubs on both sides.Note however, that since the drill bit is tapered, the adjustment of the length is limited to where the tightening screws can reach the bit shaft without harming the sharp edges. The shortest I felt was safe to go to was 1-⅜”” inches. See picture.The driving end is a standard ¼” hexagonal drive allowing quick changes if you need to use the same drill for drilling and screwing. I find that hand screwing works just as easily once countersunk.Overall length is about 4-1/2” The size (3/16”) is laser etched on the shanks for quick identification. Nice.Made in China

TIME SAVER — The Milwaukee #10 Countersink 3/16 in. High Speed Steel Drill Bit does two tasks in half the time – drill a pilot hole and countersink it. This countersink has a tapered bit which makes starting the hole easier since the bit will not walk. It makes a clean hole with a perfect countersink. See photo. The depth of the hole can be adjusted by loosening the two hex set screws on the collar, moving the bit to the desired depth, and then tightening the two set screws. It is perfect for countersinking #10 screws. All of the Milwaukee countersinks use the same collar so the maximum width of the countersink will be the same for all bits. The bits have a 1/4″ hex shank. The countersink is made is China.

I’ve gotten to like drilling pilot and/or countersink holes any time I use screws. I’ve had a number of countersink drill bits over the years, most of which have had several broken bits. This Milwaukee #10 Countersink Drill Bit is the best, by far, with features not normally seen. It has a ¼ in. quick change hex shank designed for use in drill drivers. The drill bit itself is 3/16 in., but is tapered, just like a wood screw is. The countersink base has two 1/8 in. hex set screws to secure it to the drill bit. The countersink can be adjusted on the drill bit by simply loosening the set screws and sliding it out on the bit. I found it quite cool to find a flat machined on the bit to allow securing the countersink at 1 in. out on it, without damaging the cutting edge of the flutes of the bit. Nice! The flat can (sort of) be seen in one of the photos below. It’s a bit pricier than some others, but well worth it.

I opened the package for this thing chucked it up drilled a hole and it fell apart. It has a hex base on it like so many of the insert style bits but this one is 2 piece and it is crimped to the base of the captured bit. I tried to drill a hole with it and as soon as it started to counter sink it separated. I was able to cut a clean countersink by attaching directly to the exposed bit I must say the countersink blades are very sharp and did an awesome job of giving me a precise centered clean hole.

First, the idea behind these drill bits is genius. The bit has the exact same shape or profile of the screws. Other bits would be 3/16 ths the entire depth of the hole. These Milwaukee bits are tapered so that there is the same ability for the tip to grip would at the bottom as there is at the top. Then there is the countersink at the top to allow the drill head to sit flush in the wood. Great idea.

Using Countersink bits are a must for any woodworker. You’re given the choice of counter-boring, or counter-sinking your screws with this bit.First off…It makes it rather difficult to make any adjustments to the Allen keyed set-screw when this bit didn’t come with an Allen wrench!!! Just about every Countersink bit out there comes with the proper Allen wrench. Somewhat disappointed with Milwaukee for not including this.Using this bit is very easy. You adjust the collar surrounding the bit to the desired depth, and tighten the set screw…That’s it.Overall, this is a really nice quality bit for both counter-sinking, and counter-boring in wood.Very Pleased with the quality Milwaukee consistently provides in their products.

They broke often, not any better than the Dewalts.Nothing special about these.

These MILWAUKEE COUNTERSINK HIGH SPEED STEEL DRILL BIT is an accurate #10 3/16 INCH size. The bits make it easy to choose how deep you want to make the countersink hole. The bits are tapered,so the screw is straight when you put it in. The bits are replaceable if you happen to break it. The holes are clean when drilled. These bits are nice and convenient to use.

The addition of the countersink bit definitely saves time because no additional bit change is necessary. The tapered bit appears to be a bit just as fast as a regular drill bit. The ability to adjust the countersink for depth is a good feature but it is necessary to really tighten up the screws holding the countersink in place super-tight otherwise it will be pushed along the drill. Overall this is a great addition to the toolkit that works well and saves time.

Fantastic combination drill bit for a hobbyist, production or just a few holes now and then. I have used similar tools for 35 years but this Milwaukee baby is way superior. With my old tools the drill slid in and out of the countersink and the bit shank was what went in the drill chuck. I love the hex shank that is permanently attached to the drill reducing lost time because the drill shank does not get tore up from the set screw or slipping in the chuck like my old ones did. They really designed well with 2 opposing set screws that are big enough to be useful. AND the drill is tapered to obtain the best thread strength without splitting the wood. Sized perfectly for a #10 flat head screw. This baby is really sharp and will easily go too deep so set a depth stop and pre-drill swiftly and precisely my friend.

When I was in Shop Class in school decades ago we learned how to drill the pilot hole and the clearance hole and then to countersink when using woodscrews. Seemed like a lot of trouble to me. I watched the men I knew work and they didn’t do it that way. So I’ve never been a strict follower of proper woodscrew drilling procedure. If I don’t think it will crack the wood I drill it right in. If the positioning is critical or a few other factors are present, I’ll drill a “starter hole”. I’ll enjoy using this Milwaukee #10 Countersink 3/16 in. High Speed Steel Drill Bit, that does all that proper procedure for you, in the future.
