Single Flute Insert Fly Cutter with Straight Shaft

About the Straight Shaft Single Flute Insert Fly Cutter

The 7620S Fly Cutting tool was originally designed for full-sized machines, like Bridgeport-type mills. It is also perfect for use with either our 1/2” end mill holder or ER-16 spindle. It has a 1/2″ straight shaft and is held in the spindle. It has a 1/2″ straight shaft and is held in the spindle. We have added a flat to the 1/2″ shank so our customers can use this in a 1/2″ end mill holder.

Our standard carbide insert fly cutter holder (P/N 7620) has a #1 Morse tapered shaft and is held in the 3/4 x 16 headstock spindle with a drawbolt.

This fly cutter offers several advantages over the standard high-speed steel fly cutter. Inserted carbide tips will last much longer without sharpening, plus they provide an excellent finish on hard-to-machine materials like cold-rolled and stainless steel. The cutter path is 1-1/8″ (28.6mm) wide. The cutter shape allows it to cut a straight shoulder on a part, something that cannot be done with the standard fly cutter. Once you use this tool, you will understand why 80% or more of the metal removed in modern machine shops is removed with carbide insert tools.

The cutter comes with one 2-edged carbide insert, a Torx attachment screw, a drawbolt and washer, plus a T-15 Torx wrench. Additional inserts are available through Sherline as P/N 7622.
