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

EF Chip Breaker

preferred choice chip breaker on M category material finish

M Class tolerance double sided chip breaker.  With a specially design rake angle and an inclined edge angle aimed at machining material that is highly adhesive and plasticity, such as stainless steel, EF chip breaker has a sharp edge making the cutting light and smooth, stability control chip flows and maintain surface finish, making it suitable for ultra fine and fine machining of stainless steel.
