ABRASIV Diamond Needle File 140 mm Half-Round D126 12437

With a D126 medium-coarse diamond grit electroplated onto a half-round profile, this 140 mm needle file delivers aggressive material removal on hardened steels, carbide, glass, and ceramics while leaving a controlled finish.

Overview

The ABRASIV 12437 is a half-round diamond needle file with an overall length of 140 mm and a working length of approximately 70 mm. The 3 mm bare metal shank allows direct use or fitting into a handle. The electroplated industrial diamond coating provides high wear resistance and corrosion resistance for extended tool life in precision applications.

What stands out

• Half-round shape handles both flat surfaces and concave radii
• D126 grit (medium-coarse) balances stock removal and surface finish
• Electroplated diamond coating on a 3 mm shank for rigidity
• Suited for hardened steel, carbide, glass, ceramics, stone, composites, ferrite, and graphite
