Grade
Application
CBN Grades
PCD Grades
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
QRH04
