Router Bit Speed & Feed Calculator
Calculate a practical starting spindle speed and feed rate from tool diameter, cutting speed, flute count, chip load, and your machine’s maximum RPM. Results are mathematical starting values — confirm final parameters for the exact tool, material, machine, and workholding.
YINGBA Technical Tool
Actual cutting diameter of the router bit.
Number of effective cutting edges.
Machine limit — result is automatically clamped.
Spindle speed
– RPM
Feed rate
– mm/min
Machine limit reached: the calculated spindle speed exceeds your maximum RPM and has been clamped. Increase tool diameter, reduce cutting speed, or use a machine with higher RPM.
Results are mathematical starting values. Confirm the final spindle speed, feed rate and depth of cut for your exact tool, material and machine with the YINGBA team before production.
