thereby improving the finish and removing hazardous edges.

Try to keep the drill vertical while drilling, so as not to be uneven.

About The Ram-Pro Countersink Drill Bits Kit

OUR SOLUTION:
The Ram-Pro Professional 3-in-1 Counter-sinking Drill Bits lets you Pre-drill & cone-shape the hole where the screw heads will countersunk & sit comfortably below the surface of the surroundings.

Kit also includes stop collars for controlling drill bit depth to a precise setting.
