MIR Threading Bars

This product line contains solid carbide bars designed to machine profiling and boring applications. Additionally, they can also be used in general turning jobs. They differ from basic MPR/L bars by having a cutting edge made of superhard materials like cubic boron nitride (CBN), a man-made synthetic abrasive, or CVD thick-film diamond, which possesses the highest hardness and wear resistance of all known cutting materials.
Features:

Suitable for continuous or interrupted cutting
Minimum bore diameter: 3.1 mm / 0.12 inch
Both right-hand and left-hand versions available
