Hole Drilling Bits

Down the hole bits advantage

1. The longer life of the drill : longer using life

2. High Drilling Efficiency : the drill button is wear -resistant ,so that the drill can always keep sharp ,thus greatly improving the speed of the drilling

3.The drilling speed is stable : the bit is scraped and cut to break the rock

4.Good perforemance

5.The use of a wide range : 9-grade drillability of rock,hard rock drilling

Bit face shape selection:China high air pressure mining button hard rock dth hammer drilling bits water well

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.

Our factory manufactures drill bits of various sizes, and also produces impactors and drill rods, please contact us if you need anything.

Application:

The application of DTH hammer

There are four types of end face design for high wind pressure DTH bits: end face convex type

,End face plane type, end face concave type and end face deep concave center type. Cemented carbide

mostly adopts ball teeth, spring teeth or tooth distribution mode shared by ball teeth and spring teeth

The DTH drill bit mainly used in geological exploration,coal mine,water conservancy and hydropower

,highway ,bridge,construction etc.
