Product Description

Introduction

The tungsten carbide rods with two coolant ducts is mainly used to make the solid carbide drill. It plays a good heat dissipation role when the coolant flows through the spiral hole in the high-speed processing, and ensures the cutting performance of drill and prolongs the service life of the tool. According to the Angle of the spiral hole, we make rods with two coolant ducts with helix 30°& 40°.

Miller Carbide aims to supply the first -class level tungsten carbide rods for cutting tool industry as well as the machining industry. Miller Carbide stands for more than 15 years of expertise in tungsten carbide. Patented extrusion technology, innovative grade developments, cylindrical grinding services along with our well trained employee enable us to offer you substantial price-performance advantages for high performance carbides.

Product Features

1. The use of spray drying tower to granulate, make low oxygen content in the raw material, low dirt, the apparent density and the particle fluidity and size are uniform.

2. Use high-precision extruder to mold, make the rod density uniform, size accurate , roundness and straightness high.

3. Use advanced vacuum furnace to sinter, effectively eliminate internal holes and defects, make the rod have good compactness, high strength, and good polishing performance.

4. Use special stress-relieving process to eliminate internal stress of the product and further improve the product strength and improve the microstructure.

5. Processed by the precision grinding machine, the diameter tolerance can reach H6.
