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.
