product feature

Our chisel bithave good wear-resistant and a longer service life.

1. drill bits have long service life: with the unique proprietary technology,our cemented carbide

drill bits strength ≥2800N,hardness(HRA)≥92.

2. drill bit botton do not break easily: using high strength chise tool stell, and strict technology for

heating processing, our drill bit botton have higher strength.

3. full type, our drill bit can meet the request of mining with different hardness of rock

Application:

our bore is widely using in mines, tunnels, quarries and other bore tips and drill tips needed exploitation projectstype ofchisel bit:

Q: Which grades are useful in earth drilling or boring applications?

A: In many respects the characteristics of the grades employed for earth drilling and boring represent a

compromise between the characteristics that are important for metalcutting and those that are important

for metalforming applications. Grades for earth drilling and boring must possess the highest toughness

levels for any given abrasion resistance level, while simultaneously possessing adequate strength levels.

The best compromise is usually arrived at by using grades that are based on coarse grain sizes (3 to 8 mm)

and relatively low Co levels (6 to 16 wt. %).
