Ideal for non-ferrous materials including green/sintered carbide, green ceramics and graphite

Extremely fine particle size for non abrasive applications requiring a fine cutting edge

QRD03

Larger particle size for highly abrasive materials, also for sintered carbide up to about 18% binder levels

QRD02

Excellent all around PCD grade, medium particle size

QRD01

Higher ceramic content and fine CBN particle size make this grade especially fracture resistant, especially good for severe interrupted cutting

QRL11

Generally interchangeable with QRL02, but made in America

QRL07

Low content CBN, higher ceramic component increases toughness - general hard turning, interrupted cut in tool steels, can be excellent in some iron applications

QRL07

Extremely wear resistant, good for powdered metals, including high cobalt sintered carbide, tool steels, hard facing materials, flame spray materials, cast iron

QRH06

Tool steels, baienetic iron, excellent general hard turning grade, some prefer QRL11, QRL02, or QRL07 for interrupted cut

QRH08

Excellent for cast iron, can be used for continuous cut hardened steel
