This is a kind of fine quality CNC arbor, made of fine toughness and hardness material, can provides long service life. Fine low temperature impact toughness, improved the surface gloss of the cutting pieces. It can reduce the tool grinding cost and improve the cutting efficiency. You can have a try. Features: High grip strength, impact resistance and strong, clear speed advantage in cutting off a large margin and processing. Fine toughness and hardness, long service life. It can reduce the tool grinding cost and improve the cutting efficiency. Fine low temperature impact toughness, improved the surface gloss of the cutting pieces. To maintain tight tolerances unmatched performance. User clamping and convenient way to replace, only a wrench to complete the replacement of the insert and pad. Warning: Use safety precaution such as guards and eye-protections device before using the tool. Exchange a tool when it occurs problem such as a noise, vibrations and a flame.
