Feed and Speed Charts for Carbide Drill Bits, Routers and End Mills

Use these feed and speed charts as general starting points for carbide drill bits, routers, and end mills. Actual settings may vary depending on your CNC machine, spindle speed, material, hold-down method, tool condition, depth of cut, hole depth, and desired finish.

Important: These values are starting points only. Always test on scrap material and adjust for your machine, material, and cut quality.
