  • DM Chipbreaker

    Preferred choice chip breaker on P category material semi-finish M Class tolerance double sided chip breaker with their light cutting force with wide chipping range can achieve beter results on high adhesive alloy steels.

  • YBG202 Coating

    It's suitable for milling from light to medium load and bore machining of all kinds of materials, turning of stainless steel from finishing to semi-finishing and rough turning of high temperature alloy. It's a combination of 2-4 um nc-TiAlN coating and ultra-fine carbide substrate to yield high strength and toughness. Nano structure nc-TiAln coating process ensures higher tenacity and hardness. This coating grade results in smooth surface finish on the insert, which reduce friction and increase chip flows. TiAlN (Titaninum Aluminum Nitride) has the characteristic of excellent thermal resistance and wear resistance and offers effective protection on the cutting edge of the chip breaker.
