K40 Carbide Drill Blanks H6 Wear Resistance Carbide Engraving Tool
Cemented Carbide Engraving Needle With One Tip K40 Carbide Pins
Cemented carbide has very high hardness and wears resistance, and the products are widely used in metal cutting, mechanical wear-resistant accessories, etc. High-quality carbide round rods have very high fracture toughness, so they are very suitable for making alloy needles for puncture, engraving application, etc.
Advantages of OUQI carbide products:
With high hardness and wear/corrosion resistance, suitable for the manufacturing of various kinds of solid cemented carbide tools for the machining of heat-resistant alloy and Ti alloy.
--Dimensions: diameter from 1.6-20mm, length from 15-100mm;
--High fracture toughness up to 11 Kic;
--Finished ground with circularity 0.02;
