About the Carbide Inserted-Tip Fly Cutter with Straight Shaft Single Flute Insert Fly Cutter
The 7620S Single-Flute Fly Cutting tool with a straight shaft 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 3C headstock spindle. It has a 1/2″ diameter 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, and a T-15 Torx wrench. Additional inserts are available through Sherline as P/N 7622.
