1. Mainly used for medium and small-scale carbide ball tooth for
inlay system cone drill and impact drill, drilling soft and
medium-hard rock, but also can be used for other drilling alloy
sheet.
2. With excellent wear resistance and toughness, compared with
similar products with higher speed boring.
3. Teeth long ball drill head passivation cycle, it does not wear
life is about the same diameter drill bit grinding times titles
edge life of 5-6 times, will help save the auxiliary work, reduce
workers' physical and speed up the pace.
Product advantage:
1, is made of super coarse grain cemented carbide raw materials,
100% alloy after pressure sintering, bit hardness and toughness
increased by 30% at the same time.
2, unique design, drilling and digging speed increases by 20%, and
30% increased service life.
3, industry leading after-sales support, 100% return of defective
product.
4, carbide mining ball tooth mold is complete, all kinds of shapes
and sizes may be custom production.
