Tungsten Carbide Tips C21HD Auger Bullet Teeth Hard Rock Drilling Bits
JULI is mainly engaged in the production and export of tungsten carbide products focus on the production of different cutting tools such as roadheader picks, coal mining conical picks, foudation drilling teeth, construction bullet teeth, road milling teeth and etc used in mining, tunneling, foundation drilling, construction and etc.
Our tools ensure high production rates, long service life and short change-over times together with high daily production output. We offer round shank cutter bits with shank diameters ranging from 19mm to 38/30 mm.
There are many types of bullet teeth, and the general structure is to inlay a carbide tip in a low-alloy structural steel body that has been quenched and tempered. The bullet teeth are subjected to high periodic compressive stress, shear stress, and impact load during work. The main forms of failure are the tool tip falling off, chipping and tool tip and tool body wear. Under certain working conditions, the cutter body is often broken and the teeth fails. Since the mechanical properties of the teeth body directly affect the service life of the teeth, the material of the teeth body and the effective heat treatment method are selected reasonably.
2.Unique "cutting ultra wear-resistant coating" technology, improve the wear-resistant ability, make the performance life longer and shorten the changeover times.
3.Cutting efficience and working life are higher than current market cutting picks by over 30%.
