Tempered alloy steel for proper boring rigidity. Chipbreaker breaks chips into small, tight rolls and eliminates long, stringy chips winding around tool and clogging work area. Clamp screw under bar also prevents chips from clogging screw head.Cartridges hardened to 60-64 Rockwell, and ground to .0005 accuracy to ensure proper cutting insert seating. Inserts can be indexed or replaced without loss of hole size or depth. This saves operator downtime in grinding and resetting bore size and depth when cutting edge gets dull.Flat sides on bar can be mounted in square lathe turrets or in round holes to provide three-point suspension for maximum rigidity. Adequate clearance is provided behind cutting edge to eliminate chip interference between tool and its side.All bars come with one each cartridge, clamp, chipbreaker, cartridge shim, and cutting insert. All use 3/8-inch inner circle triangle inserts.
