—MAXDRILL Down The Hole Hammer

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.

How much compressed air power is delivered to the bit is essential to DTH drilling efficiency. And our DTH equipment’s precision engineering and high standards can ensure the drilling efficiency，the hammers and bits feature solutions, which optimize impact-energy transmission into the rock. Combining advanced materials technology with skillful design focusing on performance, simplicity and endurance, our DTH tools give high productivity, great reliability and low operating 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

—MAXDRILL Drill pipes

Drill pipe is hollow, thick-walled, steel piping that is used on drilling rigs to facilitate the drilling of a wellbore and comes in a variety of sizes, strengths, and weights but are typically 30 to 33 feet in length. They are hollow to allow drilling fluid to be pumped through them, down the hole, and back up the annulus.

It is designed to support its own weight for combined lengths that often exceed 1 mile down into the Earth's crust. Used drill stem is often sent to a yard for inspection, sorted, and stored until new drill sites can be explored.

1) OD: 2 3/8” TO 5 1/2” of label 1 or 60.32mm to 139.7mm

2) Wall thickness: 6.45 to 12.7mm

3) Grade: E75, X95, G105, S135

4) Length: R1:6.1-7.01mm, R2:8.84-9.75mm, R3:12.19-13.72mm
