My shop

Tell the calculators about your routers and CNC once: the slowest and top speed, the speed dial, the collets, the power and, for a CNC, the fastest cutting feed. The router speed and feed wizard then caps every setup to the machine you pick and names the dial setting.

Your machines

Your bits

No bits saved. Save one from the bit step of the setup wizard and pick it next time.

Routers you can fill from the maker

Pick one of these and its figures come from the maker's own manual and product page; anything the maker doesn't print is left blank for you to fill, never guessed. Any other router or a CNC spindle can be typed in from its manual or nameplate.
