Review on π οΈ Anytime Tools Precision Countersink Tool Set by Shane Loredo
They do their work, but that work is limited.
Ideal if you want to place your work in the dead/live center (hence the 60 degrees). I've only used them on brass and aluminum so far, but they seem to cut well. However, I prefer spot drilling when I start making holes. A spot drill with a larger angle than the drill will keep the drill more centered. Most drills have an angle greater than 60 degrees. So when using these center drill bits to start holes, you may have trouble deflecting your drill bit.
Pros
- Very good value for money
Cons
- Problems
