Grade Property & Recommendation
|
Ultrafine grain
K180 ：
Ultrafine grade for HSC machining of tempered steel (HRC>60), abrasive aluminium, or CFRP.
UF25 ：
Ultrafine grade for HSC machining of tempered steel (HRC≤60) and stainless steel. Even more concentrated grain distribution enhances tool life and work performance.
WF25 ：
Appropriate for machining tempered steel (HRC<45) and stainless steel. It is a well-balanced high performance grade.
|
Submicron grain
 KS09 ：
Appropriate for machining stainless steels, heat-resistant alloys, & difficult-to-machine materials (Ti-based, Ni-based Alloy). Excellent performance especially under unfavorable conditions.
WF15 ：
Well balanced physical properties, very good at universal machining of alloyed / non-alloyed steel.Well balanced physical properties, very good at universal machining of alloyed / non-alloyed steel.
K200 ：
For stainless steel & heat-resistant alloys machining under work-condition of low cutting speed & high feed rate. Selective submicron carbide grade for optimum tool toughness. |
Fine
 K100L ：
Certified fine carbide grade for diamond coating tool. For machining graphite, composite material, and high-silicon aluminium alloy.
KR10 ：
Fine grain grade specially design for machining Non-ferrous metal, Cast Iron, and Plastic.
