The solid carbide head of this bit has been specifically designed for engraving signs.
The three-flute design allows the bit to "park" without enlarging the groove. Cut widths from 0.5mm to 13mm are achievable through adjusting the height of the 60° head. The cutting action is very clean.
Our professional/industrial grade bits have tungsten carbide inserts ground on CNC (Computer Numeric Control) machines using 600x diamond wheels. Tungsten carbide maintains its hardness at high temperatures and holds an edge far longer than high-carbon or high-speed steels. The bit bodies have a non-stick coating for easy resin removal.
This bit can also be used in high-speed flex-shaft machines. 1/4" or 8mm shank.
Each bit includes an advanced polymer friction-fit holder that can be mounted horizontally or upright.
