Whiteside RU5125RN Ball Nose Up Cut Spiral - 1/2″ CD x 1 1/4″ CL x 1/2″ Shank

The Whiteside RU5125RN Ball Nose up cut spiral router bit delivers precision performance for your professional woodworking projects.

Materials: Natural woods, composites, and Hard plastic. Recommended RPM: 16,000-18,000 (max 24,000) for safety.

This Ball Nose tool leaves a rounded bottom during cutting. It provides a better shear cutting angle like standard spiral bits.

These are popular with small CNC's. You can also use this Router Bit in a standard handheld router or a quality router table.

The up cut flute design pulls chips up and away from the work piece. This keeps the cut path clear and prevents any heat buildup.
