YBG202 Nano structure nc-TiAlN Coating Grade












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.  

It's a combination of 2-4 um nc-TiAlN coating and ultra-fine carbide substrate to yield high strength and toughness.  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

EM Chip Breaker


preferred choice chip breaker on M category material Medium

EM chip breaker is designed with sharp cutting edge which is required for machining highly adhesive material such as stainless steel while reinforced the impact resistance on the edge, which makes it suitable for semi-finishing and intermittent machining of adhesive materials, such as austenitic stainless steel.
