17 Bar 105mm 4 1/2'' DTH Bit Shank Cop32 Black For DTH Drilling
Product description
Each High Air Pressure DTH Drill Bit is made from quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the required hardness, given surface compression for fatigue resistance, and fitted with precision buttons manufactured in-house. These are deigned for specific applications for all rock types, hardness's and condition. Bit life and rate of penetration are the most important criteria in selecting the right bit for a particular application.

Product Advantages
1. 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 SOLLROC 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.
Face shape Features
Concave Face
1. Capable of drilling straighter holes in medium to hard rock which is broken or less consolidated
2. Offers high penetration rate in the above stated rock conditions
3. Has excellent air flushing characteristics
4. Predominant face style for majority of drilling conditions
Flat Face
1. Have a superior performance in hard, abrasive and broken rock conditions
2. They however have a slower penetration rate in comparison to a concave face bit
Convex Face
1. This face has been designed to offer high penetration rate in soft rock such as shale, limestone etc
2. They are recognized for having excellent capability for drilling into moderately consolidated rock conditions
Structure picture
Product application
At present, DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering.
DTH is one of the most efficient ways of drilling rock, using a rapid hammer action to break the rock into sizeable chips which are then evacuated from the bore hole by the air exhausted from the DTH Hammer. The technique provides fast drilling of accurately aligned, straight and clean holes in most ground conditions.
