Various non-standard carbide rotary files can be produced according to customer customization          
MATERIAL Tungsten Carbide, high hardness and good toughness, machining hardness reach to HRC65.
Rotary files have more cutting edges and will remove material much faster and leave a smoother finish than single cut due to producing smaller chips as they cut away the material.
SIZE - Shaft -1/4 inch or(6mm) Outer diameter of the tip1/8inch(3.175mm) - 31/32 inch(25mm) Total length 38 - 81mm, Suit for (6mm)or 1/4 Inch electric die grinder.

* The burr's steel shaft up to 17" (431.8 mm) long and the spring shaft up to 36" (914.4 mm) long give your workpiece more maneuverability and accessibility, while allowing you to grind hard-to-reach Location.
