Features of DTH Drill Bits:

1. Carbide Inserts: DTH drill bits are equipped with carbide inserts on the drill face, which are essential for cutting through various rock formations. These inserts are highly resistant to wear and can withstand the high impact forces encountered during drilling.

2. Bit Design: The design of DTH drill bits plays a crucial role in their performance. These bits feature a unique shape and configuration optimized for efficient drilling and maximum rock penetration. Various designs, such as convex, flat face, and concave, are available to suit different drilling requirements.

3. Shank Types: DTH drill bits come with different shank types to accommodate various drilling rigs and equipment. Common shank types include DHD, SD, and QL, each designed for specific drilling applications and rig compatibility.

4. Fluid Circulation System: DTH drill bits incorporate a fluid circulation system that helps remove cuttings from the borehole and cool the drill bit during operation. This system ensures smooth drilling performance and prevents overheating of the drill bit.

5. Diameter Range: DTH drill bits are available in a wide range of diameters to accommodate different hole sizes and drilling requirements. From small-diameter bits for precision drilling to large-diameter bits for blasting and excavation, there is a suitable option for every application.
