Product Description

Product Introduction
DTH is a reliable method that drills stable holes with exceptional straightness. The method is also excellent both environmentally and socially because it produces far less noise and vibration than many other drilling methods, making it a widely useddrilling method in cities and other populated areas
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.
Sollroc DTH bits are interchangeable with these famous bits with CIR, Bulroc, Mission,  DHD, SD, QL, etc. series shank.

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.
