DTH Drill Bits:
Down-the-hole (DTH) hammer 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 spline 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 (DTH) 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.
Characteristics
Faetures of High Air Pressure DTH Drill Bits
1.Five basic dth drill bit designs: Flat front, Convex, Speed, Concave. All shapes for all types of rock of hard, soft or abrasive.
2.Deliver maximum energy to dth drilling bit, fast drilling speed and low air consumption due to inner structure of HD series DTH hammer designed according to newest rock drilling theory.
3.Smooth performance and long service life of DTH drill bits due to high quality alloy steel materials and advanced processing technology adapted.
4.Low problem rate and easy to maintenance due to simple , reliable and easy assemble and disassemble inner structure of DTH drill bits.
5.Easy to depart the dth bit from hammer due to multi-head thread connecting chuck and cylinder of hammer.
