Bit face shape selection:factory supply cheap price mining hard
rock well drilling DTH hammer drill bit set
1. Drop Center Bit For high penetration rates in soft to medium
hard and corrosive rock formations. Low to medium air pressures.
Maximum hole deviation control.
2. Concave Face
The all-round application bit face specifically for medium hard and
homo generous rock formations. Good hole deviation control and good
flushing capacity.
3. Convex Face
For high penetration rates in soft to medium-hard with low to
medium air pressures. It is the most resistance to steel wash, and
may reduce the load and wear on the gauge buttons, but poor hole
deviation control.
4. Double Gauge Face
This kind of face shape is suitable for fast penetration rates in
medium to hard rock formations. Designed for high air pressures and
good resistance to steel wash step gauge bit.
5. Flat Face Bit
This kind of face shape is suitable for hard to very hard and
abrasive rock formations in applications with high air pressures.
Good penetration rates an resistance to steel wash.

we has a comprehensive range of DTH drill bits to match all
conceivable applications. Each bit is made from quality alloy
steel, and has been precision machined to produce a perfect body,
heat treated to the required hardness, given surface compression
for fatigue resistance, and fitted with precision buttons
manufactured in-house. These are deigned for specific applications
for all rock types, hardness's and condition. Bit life and rate of
penetration are the most important criteria in selecting the right
bit for a particular application.
