KINGDRILLING DTH taper drill bit description:
Tapered chisel drill bits have different tapers and are used for different rock formations and rock drilling. Tapers of 11° and 12° are common on modern drill rigs. The narrow taper of 7° is used for low impact rock drills and softer rock formations.
Widely used for drilling large diameter holes in rocks for water well drilling. Oil fields, coal mines, tunnels, mineral exploration, geothermal drilling, subway engineering drilling. Quarrying and construction projects such as roads and power stations. Suitable for extremely hard, abrasive rock formations, medium hard, homogeneous formations. Soft rock, fissure rock formation, etc.
All tapered chisel drill bits are made of high-quality raw materials and undergo special heat treatment. They have extremely strong conveying capacity and can fully meet customers' requirements for conveying design.

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.
