Product description

Down-the-hole drilling is to drive the hammer which behind the drill bit by compressed air via the drill pipe. The piston strikes the bit directly, while the hammer external cylinder gives straight and stable guidance of the drill bit. This makes the impact of energy is not lost in joints and allowing for much deeper percussion drilling.

Furthermore, the impact force acts on the rock at the bottom of the hole, which is more efficient, and straighter than other methods of the drilling operation.

DHD360-165mm DTH Drill Bit overview

Product Advantages

1. 1.Five basic dth drill bit designs: Flat front, Convex, Speed, Concave. All shapes for all types of rock of hard, soft or abrasive.

2.Deliver maximum energy to dth drilling bit, fast drilling speed and low air consumption due to inner structure of HD series DTH hammer designed according to newest rock drilling theory.

3.Smooth performance and long service life of DTH drill bits due to high quality alloy steel materials and advanced processing technology adapted.

4.Low problem rate and easy to maintenance due to simple , reliable and easy assemble and disassemble inner structure of DTH drill bits.

5.Easy to depart the dth bit from hammer due to multi—head thread connecting chuck and cylinder of hammer.

Face shape Features

Concave Face

1. Capable of drilling straighter holes in medium to hard rock which is broken or less consolidated

2. Offers high penetration rate in the above stated rock conditions

3. Has excellent air flushing characteristics

4. Predominant face style for majority of drilling conditions

Flat Face

1. Have a superior performance in hard, abrasive and broken rock conditions

2. They however have a slower penetration rate in comparison to a concave face bit

Convex Face

1. This face has been designed to offer high penetration rate in soft rock such as shale, limestone etc

2. They are recognized for having excellent capability for drilling into moderately consolidated rock conditions
