Carbide Grade Selection Choose the CPT grade specifically formulated for your application from the following list: Coated Grades
HBA
PVD triple layer coated sub-micron grade for stainless steels, cast iron, titanium, non ferrous metals and most of the high temperature alloys. Extra-fine sub-micron grade with high toughness, for optimized performance on hardened steels and cast iron up to 62HRc, titanium alloys and super alloys (hastelloy, inconel and nickel based alloys). PVD TiAlN coated sub-micrograin grade for stainless steels and exotic materials at medium to high cutting speeds. PVD TiN coated grade for treated and hard alloy steels (25 HRc & up) at medium to low cutting speeds. PVD TiN coated micrograin for free cutting untreated alloy steels (below 30 HRc), for stainless steels and cast iron.
BMA (P20-P40) (K20-K30) P25C (P15-P35) MXC (K10-K20) (P10-P25) BLU (M10-M20) (K05-K20) (N10-N20) (S10-S20) (H10-H25) (S10-S25) BXC (P30-P50) (K25-K40)
PVD TiN coated grade for low cutting speed. Works well with wide range of stainless steels.
Uncoated Grades
P30* K20* (P20-P30) (K10-K30)
Carbide grade for carbon and cast steels, works well at medium to low cutting speeds.
Carbide grade for non ferrous metals, aluminum and cast iron.

Type B - Threading Inserts A combination of ground profile, and sintered chip-breaker threading inserts. Unlike most other manufacturers inserts, this combination ensures a consistent high quality thread, with precise shape and dimensions. Two different unique styles of chip-breaker were designed to suit the different specific requirements of Internal threads and External threads. All of CPT Type B inserts are made of BMA Sub-Micrograin grade.
