Metal Master HD - Additional Details
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. So, now you don't have to make the tradeoff between weak, free cutting, high shear positive rake inserts, and strong, horsepower gobbling negative rake geometries. Now you can have the best of both, and it only gets better from here.
Rigid body
Built for maximum rigidity. Minimizes deflection, which might result in poor surface finish.
Deep Pocket Design
Rigid support for entire circumference of the insert.
Solid Shield
Surrounds insert and directs cutting forces into solid body. Much safer in operation.
Positive location
Precision-machined insert seats assure accurate location and improved surface finishes.
