Woodworking
Router Speed Calculator
Find the optimal RPM for your router bit based on bit diameter, material type, and cut type. Use it to prevent burning, tearout, and bit damage on wood, plastic, or metal workpieces.

Woodworking
Miter Angle Calculator
Compute the miter angle to cut on each end of a piece in a regular polygon frame so the joints meet flush. Useful for picture frames, hexagonal and octagonal projects, coopered cylinders, and any segmented work where pieces join at equal angles.
