Long Life Span Oil / Mining Drilling Tools , Alloy Steel Borewell Drilling Hammers

Description

Down the hole rock tools (drilling tools) are rock drilling equipment which takes compressed air as power source to partially transfer impact power into drilling holes. An air distributing device in a top hammer controls a piston to move back and forth. An impact device arranged in the front of the top hammer transfers the impact powderto a down-the-hole bit to crush rocks.

1. Based on previous experience of ordinary hammers, combined with the features of reverse circulation hammer, optimized internal structure and ideal energy transfer, thus ensuring the series of hammers drilling with fast, smooth and continuous sampling.

2. The internal structure is very simple with components of high rigidity, thus ensuring long life and easy maintenance of the hammer.

3. The collection tube adopts an integrative design and can be replaced without disassembling the hammer. With carburizing treatment, it has good abrasive resistance.

4. Equipped with bits designed with patent. Simply by replacing the drill bit, the same hammer
can drill holes of different sizes ensuring that the sample is not contaminated.

5. In difficult conditions such as loose soil, hard rock and plenty of water exists, sampling can be done well.

Applications

All our products, which passed ISO9001 quality management system, are widely used in open pit mining,tunneling, quarrying, transportation construction,engineering, earth-rock excavation, water wells, pile foundation, and civil engineering project etc. We are one of the companies which have the most complete product lines, the most abundant species and the most widely used products in drilling industry.

Specifications

1. Using the latest rock drilling theory,optimizing the inside structure and the size of the air distrbution,to make the DTH hammer obtain the optimal energy transfer and make it achieve faster drilling speed and lower air consumption.

2. For such projects as the drill bit break,retrieving very difficult,we specially designed a safe and reliable anti-shedding device for the bit.

3. The check valve can be replaced to replaced to the one with bigger air controlling hole to provide more efficient cutting discharge.

4. The top sub and the drive chuck have special thread,which can achieve an easier disassemble.

Feature Advantage

1. Fast drilling speed and low air consumption due to the special inner structure.
2. Smooth performance and long service due to high quality alloy steel materials and advanced processing.

Technology adapted

1. Low problem rate and easy to maintenance due to simple, reliable and easy assemble and disassemble inner.

Structure of hammer

1. Easy to depart bit from hammer due to multi—head thread connecting chuck and cylinder of hammer.
2. Interchangeable with DTH bit and drill pipe.

The appearance of the picture is different from that of the actual product, and the actual product is the standard.
