® Tiny Tools Technical Section Carbide Grades: BXC (P30 - P50, K25 - K40) PVD TiN coated grade for low cutting speed. Works well with a wide range of stainless steels. BMK (K10 - K20) Sub-micron grade with advanced PVD triple coating. Extremely high heat resistant and smooth cutting operation, for high performance, and normal machining conditions. General purpose for all materials. K20 (K10 - K30) Uncoated Carbide grade for non ferrous metals, aluminum and cast iron. TNX New advanced carbide grade TNX for higher feeds and high performance, at medium to high cutting speed. Extra fine grain size with high hardness and toughness combined with triple layer reddish coating, provides high edge stability and better chip flow. Available only for CBR bars.
