Our cemented carbide slitters are excellent cutters for magnetic tape, capacitors, paper, plastics and metals and offer good durability 10 times greater than that of steel.
Cemented carbide slitter knife units are also manufactured.
Metal-slitting saws are used for metal-slitting of magnetic heads, frames of glasses, etc.

※Designed and manufactured according to your requirements.
