Product Introduction

Down-the-Hole drilling is one of the fastest, most dominant methods of geotechnical drilling. DTH drilling has many applications, including water well, oil and gas, blast hole and foundation drilling. This is an energy efficient form of wide-hole drilling (in the hole range of 100-254 mm) that can be performed in both a downward and an upward direction.

DTH (Down to Hole) drill bit, also called spline connected drill bit, is mainly used in large scale mine (open and underground), open quarry and construction. The hammer is situated down the hole in direct connected with the drill bit with splines in the bit. The hammer piston strikes the drill bit resulting in an efficient transmission of the impact energy and insignificant power losses with the hole depth.




Product Features

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.
