Introduction

Three straight holes rod is a kind of round rod and the center of holes are the center of equilateral triangle, which with high T.R.S. and good impact toughness. The circular bar has a spiral look uneven structure. Contract with existing technology, the utility model is a solid tool holder made not only more reliable, but also the use of high strength and good impact toughness.

Application

Tungsten carbide three straight holes rod are widely used in drills, end mills and reamers, also use as cutting, punching and measuring tools. It is widely used in papermaking, packaging, printing, non-ferrous metal processing industry. In addition, it is widely used in high speed steel cutting tools, carbide cutters, carbide cutting tools, NAS cutting tools, air tools, carbide drill bits, cutter core drill HSS, taperd cutter, Metric cutter, micro end milling cutters, reamers pilot, electronic tools, step drills, metal cutting saws, double guarantee diamond, guns, angle cutters, carbide burrs, carbide cutting tools.

Processing

The main processing of tungsten carbide three straight holes rod is powder→ burden→ wet milling→ mixing→ smash→ dry→ sieved→ added forming agent→ dry again→ after sieving prepared mixes→ granulation→ suppress→ forming→ low pressure sintering→ forming(blank) →drilling→ polishing→ checking→ package→ warehousing
