WOOD magazine review

Drill countersinks & pilot holes in 5 sizes

Review Summary

Nothing exotic here: just twist bits in steel cutters sized for #4–12 screws. In our tests, every piece in the set cut clean countersinks and 3/8" or 1/2" counterbores in quick fashion. As a nice touch, the manufacturer stamps the countersinks with the size of the matching bit. The ¼" hex shanks make for quick in-and-out connection in any hex-chuck drill/driver.

Solid workhorse for many years

Review Summary

I've had and used this set of Insty bits in my shop for almost all the years I've been a woodworker( Over 20) and they have held up very well. They don't stay sharpened as long as my carbide ones but cost a whole lot less and are easily sharpened, which I've only had to do a couple of times, so all in all a very nice set of bits that do the job and hold up over many years of use.
The drill bits stay locked in position and I've never used the drill bits with the flat side on them, which don't come with this set anyway. If your countersinking your screws and plugging the holes this is the set to get. They leave a nice accurate hole for your plugs to go in. And do yourself a favor and purchase , along with this, a set of quality tapered plug cutters.

My well used countersinks

Review Summary

I have been using these countersinks for about 5 years. They perform extremely well and produce quality results. The jobber drill bits (drill bits with flat side) prevents slippage or twisting, although you can use standard drill bits if replacement is needed in a pinch. Whether you are a serious woodworker or a occasional hobbiest and want to do a quality job, I recommend investing in the Insty-bit collection.
