Small tools built for the manual shop. No fluff, no signup — just the numbers you need at the machine.
Enter your tool diameter, material speed, and spindle range — get back the RPM to set and the seconds you have to cross the cut. Stop rubbing, start cutting.
Pick a thread standard and get the correct drill size, with clearance options for through-holes and blind holes.
Lathe equivalent of the mill calculator. Set your insert grade, material, and depth of cut to get spindle speed and feed rate.
