Product Description

Product Description

Because of economy and powerful drilling capacity, down the hole hammer become an advanced drilling tool for drilling and mining industries. Down the hole hammers and drill bits are designed together to work in perfect unison, giving high penetration rates, long service life and low costs.

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

2. Smooth performance and long service life of HD series DTH hammer due to high quality alloy steel materials and advanced processing technology adapted.

3. Low problem rate and easy to maintenance due to simple , reliable and easy assemble and disassemble inner structure of hammer.

4. Easy to depart bit from hammer due to multihead thread connecting chuck and cylinder of hammer.

5. Interchangeable with DTH bit and drill pipe

Low pressure and high pressure hammers are available in our company.

Technical parameters:

Length(Less bit)	Weight	Outer diameter	Connection Thread	Bit Shank	Hole Range
928mm	25Kg	¢82mm	API2 3/8"REG	DHD3.5	¢90-¢110mm
Work Pressure		Recommended rotation speed		Air Consumption 1.0Mpa	Air Consumption 1.5Mpa
1.0-31.7 Mpa		30-60 r/min		4.5m³/min	8.5m³/min

Valveless air distribution.More reliable.

Simple design of the piston.long life span.

More effcient energy transfer,faster drilling speed,lower air consumption and lower oil consumption.

Fewer intemal parts,simple structure,long life span,less failure and easier to maintain because all the parts are heat trated.

Easy to disassemble because the top sub,the drive chuck and the extemal cyinder are connected by muitiple steps thread.
