KINGDRILLING DTH taper drill bit description:
The tapered cross drill bit has strong impact resistance and can be used in any rock drilling conditions. Full adaptability. Compared to tapered chisel drill bits, tapered cross drill bits have better drilling performance because the carbide tip on the cross drill bit is doubled, which means the carbide shape on the drill bit is cross-shaped. Taper cross drill bits are mainly used in hard or very hard rock formations.
The tapered cross drill bits produced by our company are made of high-quality carbide and processed by heat treatment. They are connected to the air-leg tapered drill pipe well or hand-held rock drill. They are suitable for gold mines, coal mines, marble, and granite quarries. , drilling in stone engineering, tunnels, water conservancy and other fields.

How to order
Tapered Drill Bits: Bit Diameter + Taper Degree + Socket Diameter.
Function:
1. The tapered drill bit has high technical content, long drilling time and high drilling efficiency. According to carbide blades, tapered button drill bits can be divided into hemispherical, conical, parabolic and other types.
2. Hemispherical button drill bits have high load-bearing capacity and wear resistance, while tapered button and parabolic button drill bits have high drilling speed and low wear resistance.
3. Made of high-quality raw materials with special heat treatment, especially tungsten carbide taper drill bits, which are widely used in handheld (short hole) drilling systems for large-size quarrying.
Kingdrilling tapered drill button bits application:
1. Mineral
2. Tunneling & Underground Project
3. Construction Drill And Blast
4. Quarrying & Aggregate
5. Hydropower Project

FAQ:
1.What is the general delivery time?
15 working days for DTH bits.
20-25 working days for DTH hammer
3-5 working days for ex stock items.
2. Competitive pricing:
A: Since KINGDRILLING factory sells directly to consumers without the need of a distributor, it can provide you the best price.
3. How do I select the DTH drill bit's appropriate head face?
Concave: Excellent for perpendicularity of the hole and appropriate for drilling deep wells in a variety of formations.
Convex: Good drilling efficiency, moderate borehole perpendicularity, and appropriate for the development of strata with a moderate degree of hardness.
Flat: This type of drilling is well suited for tough strata, particularly those with fractures, adequate fracture spacing, and a well-perpendicular borehole.
4. A feature of the product
Innovative electron-hydraulic forging hammers are used to forge kingdrilling DTH tools, and multipurpose furnace heat treatment controls the harness process.
