Carbide Tipped Drill Bits “MR.TWISTER™”

Note in the picture, the cross section of the spiral shank has nearly as much “meat” as our straight flute bit and therefore achieves the desired results in strength and heat dissipation. Also notice the cutting edge.

By sharpening the bit in a notched fashion, we end up with more cutting surface as compared to common straight-edge sharpening techniques.
