COP 32 High Performance Drilling Equipment For Mining DTH Rock Drill Button Bits
Down-the-hole (DTH) bits are used with Down-the-hole hammers for
drilling holes through a wide range of rocks types. In conjunction
with DTH hammers, drill hammer 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.
Our variety of Down the Hole drill bits is manufactured using high
quality materials to provide you with a fine balance between
penetration capability and bit life. We offer a comprehensive range
of standard and made to order drill bits on an extensive selection
of shanks with a wide variety of head designs to suit every
project.
Bit face shape selection:
1. Drop Center Bit
For high penetration rates in soft to medium hard and fissured rock
formations. Low to medium air pressures. Maximum hole deviation
control.
2. Concave Face
The all-round application bit face specifically for medium hard and
homogenerous rock formations. Good hole deviation control and good
flushing capacity.
3. Flat Face Bit
This kind of face shape is suitable for hard to very hard and
abrasive rock formations in applications with high air pressures.
Good penetration rates an resistance to steel wash.
4. Double Gauge Face
This kind of face shape is suitable for fast penetration rates in
medium to hard rock formations. Designed for high air pressures and
good resistance to steel wash step gauge bit.
5. Convex Face
For high penetration rates in soft to medium-hard with low to
medium air pressures. It is the most resistance to steel wash, and
may reduce the load and wear on the gauge buttons, but poor hole
deviation control.
