High Strength DHD340 DTH Button Bits 110mm Bit Dia High Air Pressure

High Strength DHD340 DTH Button Bits 110mm Bit Dia High Air Pressure

DHD340 110mm (4 1/2 Inch) Button Bit DTH Bit

Shanks: DHD340, Mission40, SD4

Application: Mining Drilling Hole Blasting

Bit Face Shape Selection:

1. Flat Face

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.

2. 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 theload and wear on the gauge buttons, but poor hole deviation control.

3. Concave Face

The all-around application bit face specifically for medium hard and homogeneous rock formations.
