1. The arc is smooth, the surface is smooth, not easy to block, and reduces heat generation 2. Use high-quality alloy materials as the rod body to increase the service life and increase the finish 3. Not easy to wear, high-quality materials, high strength, eliminating the trouble of frequent replacement Recommended Usage YG10X Use widely, with good hot hardness. Suitable for milling and drilling general steel under 45 HRC and Aluminum, etc at a low cutting speed. Recommend use this grade to make the twist drills, end mills, etc. ZK30UF Suitable for milling and drilling general steel under HRC 55, cast iron, stainless steel, aluminum alloy, etc. Recommend to make the drills, milling cutters, reamers and taps. GU25UF Suitble for milling titanium alloy, hardened steel, refractory alloy under HRC 62. Recommend to make end mills with high cutting speed and reamer.1.Using over 99.95% high purity tungsten carbide powder, it has a better strength and hardness combined with a longer service life than the normal one. 2. Using ultrafine grain size of tungsten carbide powder to produce,Hardness can reach to HRA93.6, Bending strength can reach to 4000N/mm² 3.Tolerance can reach to ±0.001mm, straightness can reach to ±0.02mmWhy choose us: 1.High Quality carbide Rods ISO9001 certified 2.Automatic pressing, HIP sintering technology 3.Good abrasion resistance and high hardness 4.Prompt aftersales service within 24 hours 5.OEM  and  customzied  order  accepted 6.Diameter from 3-25mm, overal length 20mm to 330mm 7.Suitable for making drill bits,end mills,reamers and PCB tools etc.
