Cop 34, Cop 32 DTH Hammer

Cop 34 DTH Bits, Cop 32 DTH Hammer for blast hole drilling and water well drilling projects

 

 


DTH Drill Bits are produced from premium quality nickel-alloy steel for increased durability and wear characteristics. Specific heat treatment standards and special "stress relief" processes ensure consistent performance. DTH hammer bits are designed for maximum performance and hole cleaning ability and high penetration rate.

 

"Down-the-hole" (DTH) drill bits are used with "Down-the-hole" hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill bits are designed with a splined drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes.

 

All ROSCHEN’s DTH drill bits are also CAD designed, CNC manufactured for perfect bits body, and multiple heat-treated to enhance hardness, surface-compressed for fatigue resistance, all thus to extend the product life for maximum wear and performance in the toughest of drilling conditions.



Product Description:

1. Specific heat treatment standards

2. Premium hardened steel alloy

3. High-grade cemented tungsten carbide buttons.

4. Certification: GB/T 19001-2008/ISO 9001: 2008


 

 

Application:

1. The down-the-hole drilling tool is used to drill large-diameter holes in rocks, usually in the initial stage prior to blasting, but it is also used in non-blasting application.


2. DTH drilling are used mostly in mining quarries, but can be used in a variety of other construction application.


3. The DTH drilling method is growing in popularity, with the increase in all application segments, including blast-hole, water well, foundation, oil & gas, cooling systems and drilling for heat exchange pumps.


4. Applications were later found for the underground DTH method, where the direction of drilling is generally upwards instead of downwards.
