Choosing bits

when choosing a bit that is not in the stock set of bits how do you enter the bit size? do you enter the cutting diam for the bit? any help appreciated thanks

Enter the bit cutting diameter. If a vbit, and it has a flat tip, enter that ie. .015

Yes as Phil explained for V-Bits. And for the standard bits with flat bottoms, yes you enter the exact cutting diameter after clicking on the “other” box in bit selection. Enjoy !

thank you guys for the responses
