Metal Master: Fly Cutters

The cutting edge is on the inside! The secret of Metal Master's performance is a patented insert geometry that puts the cutting edge on the inside of the round insert.

This revolutionary design puts the mass where it's needed most, in support of the cutting edge, while keeping it out of the way during the cut.

Indexing is done quickly and easily on the machine. Simply loosen the screw, rotate the insert, and tighten the screw. Minimizes non-productive downtime.

The result is a positive shear angle of 60 degrees, in an insert that's inherently stronger than any conventional round insert of comparable size, positive or negative.
