6. Bit Face
RazorcutTM design is ready-to-cut right out of the box and improves tracking and balance in the hole.
7. Crown
Available in an extremely wide variety of formulations, the crown is the cutting edge of the bit.
8. Throatless
Older designs had a small counterbore in the inner diameter (ID) at the start of the crown, referred to as a throat. This feature could accumulate material and accelerate ID gauge loss and has been eliminated in new designs.
9. Taper
Newer designs of bits have a taper on the outer diameter (OD) to smooth the transition of cuttings from the waterways up the hole, improving flushing.
