Low-pressure down-the-hole drill bits are rock drilling tools designed for use with low-pressure down-the-hole drilling rigs. They are primarily used for efficient and stable drilling in low to medium hardness rock formations and are widely applied in various engineering fields such as mining and quarrying.

HENGLONG Low Air Pressure DTH Bits Features:

Fabricated with high-strength alloy for durability and wear resistance

Main body made of high-strength alloy steel with special heat treatment

Teeth made of cemented carbide material for high durability

Excellent diameter protection maintains drilling size after wear

Longer service life than ordinary general-purpose drill bits

Easy to install and maintain, reducing overall costs

HENGLONG Low Air Pressure DTH Bits Face Shape Selection:

Face Shape	Use Condition
Concave Face	The all-round application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good flushing capacity.
Convex Face	For high penetration rates in soft to medium-hard with low to medium air pressures. Most resistant to steel wash, may reduce load and wear on gauge buttons, but poor hole deviation control.
Flat Face	Suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates and resistance to steel wash.

HENGLONG Low Air Pressure DTH Bits Button Shape Selection:

Button Shape	Use Condition
Domed/Round Button	Usually used as gauge buttons of DTH Bits, suitable for very abrasive and very hard formations.
Parabolic/Semi-Ballistic Button	Usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.
Ballistic Button	Usually used as front buttons of DTH Bits, suitable for medium abrasive and medium hard formations. Can also be used as gauge buttons if the rock is soft.
Sharp Button	Usually used as front buttons of DTH Bits for soft formations where fast penetration rates are possible and button breakage is minimal.
Flat Button	Usually used as protection buttons to reduce wear on rubbing surfaces of DTH Bits.
