Fly Cutter

About the Fly Cutter

Fly cutters are used primarily on a milling machine for machining large, flat surface areas. The fly cutter is a single-point cutting tool similar to a lathe tool mounted in a special holder. The cutter can be adjusted to cut up to a 2.00″ (51 mm) diameter and is easily capable of taking a .010″ (.25 mm) deep cut in aluminum at this diameter.

The Sherline fly cutter comes complete with the holder, a drawbolt, thrust washer, and a left-hand brazed 1/4″ carbide cutting tool. It is a worthwhile addition to any shop.

Sherline also offers an inserted tip fly cutter (P/N 7620) for those who prefer to work with inserted tip carbide tools.

This Model 5400 mill has been converted to 8-direction capacity with a P/N 5650 column upgrade. The adapter base can be seen in the background. A fly-cutting operation is underway.
