The cutting edge is sharp and wear-resistant, it is not easy to break the edge, the surface is clean and free of burrs, and the finished workpiece has high smoothness.
The high-frequency welding process is adopted at the connection between the cutter head and the cutter body, which is durable and not easy to break the knife, which greatly improves the practical life of the cutter.
The concave surface of the measuring edge reduces the friction between the end surface and the groove. The secondary declination makes the tool more wear-resistant, the tool is hardened and the strength is higher.
Uses: Used To Process T-Shaped Grooves On Various Mechanical Tables Or Other Structures.
8 tooth head design, cutting efficiency is higher.
