TRUSCO CBN File for Metalworking, Set of 5, Semi-round, CBNK-5-HA, 1 piece

Catalog number: CBNK-5-HA Features: ● Good compatibility with heat-resistant superalloys, high-speed steels (HSS), die steels, and other high-hardness, difficult-to-cut metals (sintered alloys), and mainly metals containing iron. ● Abrasive grains with hardness second only to diamond. ● The sharpness of the abrasive grains is maintained until the end. ● The heat resistance of diamond abrasive grains oxidizes at about 600°C in air, but CBN abrasive grains oxidize at about 1000°C. ● Abrasive grains with better heat resistance. ● The base metal is elastic and fits the workpiece. ● The file base metal is firmly held in a stable state by our proprietary electroplating technology, so the initial sharpness is maintained until the end. Applications: ● Ideal for rough cutting of burrs and rigid workpieces. ● Finishing, correction, and R-removal of various molds, grinding of various blades, grinding of glass, ceramics, and all hard materials. Specifications: ● Grit (#): 140 ● Type: Set of 5 ● Shape: Semi-round (width) 12.0 x (thickness) 3.75 ● Total length (mm): 215 ● Blade length (mm): 80 ● Handle shape: Flat ● Metalworking type (#140) Note: ● Set of 8 and set of 10 are common names that describe the size of the files, and do not mean a set of 5, 8, 10, or 12.
