Work well, good starter hole, flush screw head & no Slip

Different sizes for what you need. Great price, and easy to use

Rebuilding my deck and definitely putting these to the test. Did break the 1/8" bit but put in another bit and got back to work. No complaints

they are very sharp

It's nice to have the different sizes of counter sink bits. We use different gauge screws, so it makes sense to have different size bits. I like these.

works good but I constantly need to keep tightening retaining screw. If you need to countersink a ton of screws buy a better countersink. but for occasional use its ok

Easy to use and sharp

Item arrives on time and exactly what I ordered. Needed a way to connect boards of a project I’ve been working on but wanted to make sure the screws I used would be able to be hidden. This item did exactly that and now I can install screws beneath flush with the wood and then add a dowel rod to hid the screw. Would buy again.

I was working on a project when I received, they got on job site write of way, they are exactly what I was looking for, cut in melamine left a nice pattern , happy

I prefer the tapered-point style of countersink, but didn't have the sizes I needed, so I ordered these to finish the job. I was pleasantly surprised with their performance in hardwood, although I have not tried them in some of the very dense hardwoods, such as ipé, only common domestic hardwoods such as the oaks. I can't vouch for their longevity, of course, since I only received them recently. But no breakage or bending so far.

I tried to use the bits, even when totally new they cut very slowly though the (soft) wood. I don't recommend.

Merci

Works great
