45 degree inside and outside positive and negative chamfering cutter upper and lower bore reverse pull chamfering cutter bar

1. Preferred steel materials, anti-vibration and durable
The whole tool is made of 42CrMoTi alloy steel with obvious anti-vibration effect, which can effectively inhibit vibration and improve the anti-vibration strength.
2.Hardened shank Easy cutting
The toolholder is hardened by quenching and hardening process with high hardness coating, high hardness and no deformation, which can be used for strong cutting and more than general milling cutter feed, effectively saving time and improving efficiency.
3.Tight fit without chipping the inserts.
Screw off-set fastening design, so that the insert groove and inserts close fit rigidity, processing efficiency is good without chipping, improve the life of the cutter bar, safe continuous machining
