Whiteside RU1600 1/8-inch upcut spiral

When to choose it

The RU1600 suits a fine guided groove where a nominal 1/8-inch width is needed and an upcut spiral helps draw chips out toward the router. The larger shank still requires a quarter-inch collet.

The narrow cutting section and half-inch flute length distinguish it from the quarter-inch RU2100. Check the router side of a fragile surface on a test piece and use the model instructions for the actual pass.
