The EZE-LAP Diamond Needle Files are ideal for engineering, woodworking, and DIY sharpening jobs thanks to the high quality diamond surface. They are 1/4 thick, with the diamond surface on a solid stainless steel substrate. The ergonomic soft grip handles are colour coded to show which grit the file is. Red handles are fine grits, and purple handles are coarse. The files are supplied in a pouch. Gunsmiths, tool and die makers, jewellers, stockmakers, rely on EZE-LAP needle files to get the job done. EZE-LAP offers twelve different shapes of diamond needle files. Two durable efficient grits are available Fine (600 Grit) and Coarse (250 Grit). 5.5 inches (14 cm) overall length (O.A.L.) and shank diameter of 0.118 inches (3 mm). By using an EZE-LAP product, high quality and consistent finishes can be achieved on your tools. No oil or water is necessary, the surface will remain true and flat.
