This Amana 1/4" shank extra long router bit was specially designed for 2D and 3D CNC cutting operations. The extra long shank allows for deeper reach and better chip clearance. With the 1/4" diameter 1/8" radius ball end, you can remove bulk material faster before you switch to a smaller bit for greater detail. The gold ZrN coating acts as a lubricant and greatly extends the tools life. Â
