They are FLAT on the bottom

They are not "self centering". If the outside diameter matches the hole, good. But what I usually want is a cone shaped bottom centered in a hole of about the right size. Not this one.

Pros
  • Hex Shank Drill
Cons
  • They could have chosen a newer model

Center Drill Bit Sets save a lot of time

I use these drill bit sets to install hinges, cornices, etc. The self-centering properties of each drill bit provide an effective method of drilling a group of holes right in the middle.

Pros
  • Power Tools and Hand Tools
Cons
  • New Competitors Have Popped Up

What a time saver! in Electric Drill Parts and Accessories

Used to drill mounting holes for new cabinet hinges. The bit does exactly what it says on the tin and it gave me a perfectly centered hole. It was nice not having to worry about the bit going around and then having to turn the screw in. Time will tell how long they last, I have many more doors to make and hopefully these will hold up.

Pros
  • Electric Drill Parts and Accessories
Cons
  • I don't remember
