The 3052S Fly Cutting tool was designed for those who are using an ER-16 or 3C headstock. Our standard fly cutter holder (P/N 3052) has a #1 Morse tapered shaft and is held in the 3/4 x 16 headstock spindle with a drawbolt. The 3052S holder has a straight shaft and is held in the spindle using a 3/8″ collet.*
*NOTE: Sherline Products does not sell 3/8″ collets used with the ER-16 or 3C headstock spindles. Those are available through Hardinge Inc. or other tool supply sources.
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 with straight shaft comes complete with the holder and a left-hand brazed 1/4″ carbide cutting tool.
Sherline also offers a boring head with a straight shaft (P/N 3054S) for use in an ER-16 or 3C headstock spindles.
