Product Description
Tapered Chisel Bit is a precision drilling tool with a flat, chisel-shaped cutting edge, designed for rock breaking and hole drilling in construction and mining. It features a tapered shank for tight connection with drill rods, delivering strong impact transmission, stable operation, and precise hole formation in medium to hard rock.

Material
Made of high-quality high-speed steel (HSS) or tungsten carbide-tipped alloy, Tapered Chisel Bit undergoes professional heat treatment. This process enhances hardness and toughness, enabling it to withstand high-impact drilling without edge chipping.
Product Advantages
Efficient Rock Breaking:
The flat chisel-edge design helps to focus the impact energy. This boosts drilling speed in hard rock by thirty percent compared to standard drill bits.
Long-Lasting Performance:
These drill bits are made from a special alloy steel that resists wear. A single bit can drill over three hundred meters. This means you do not need to replace the bit often.
Universal Compatibility:
The tapered shank fits with drill rod sizes. For example it works with Φ22 and Φ25. You can replace existing bits directly without changing your equipment.
Stable Precision:
The cutting edge is ground precisely. This ensures that the drilling diameter is accurate to, within half a millimeter. As a result you do not need to ream the hole.
Applications
- Mining industry: Tapered Chisel Bit is used for drilling blast holes in coal, iron, and non-ferrous metal mines.
- Construction engineering: Hole drilling for foundation reinforcement, slope stabilization, and road construction.
- Quarry operations: Breaking granite, limestone, and other stone materials for building aggregates.
- Municipal projects: Drilling for pipeline laying and tunnel excavation in urban infrastructure.
Packaging & Logistics
For the overseas market, we utilize export-grade reinforced wooden crates or steel cases for packaging. The interiors feature anti-rust and shock-absorbing treatments to withstand the rigors of long-distance sea and land transport. Additionally, we provide a complete set of customs clearance documentation-including commercial invoices and certificates of origin-and facilitate various trade terms such as FOB and CIF. We ensure that the entire order process, from production to shipment, is completed within 7 working days, guaranteeing safe delivery to the client's designated destination port.
Frequently Asked Questions (FAQ)
Q: Which strata is the Tapered Chisel Bit suitable for?
A: It is mainly suitable for medium to hard rock, limestone, granite, and compacted soil, and not applicable to extremely soft or loose sand formations.
Q: How to select the appropriate model of Tapered Chisel Bit?
A: Based on the drilling diameter (10mm-25mm), drill rod taper (6°-12°), and engineering requirements, match the corresponding model (e.g., TC-25 to TC-50).
Q: What is the service life of the Tapered Chisel Bit under normal use conditions?
A: For medium-hard rock, a single bit can complete over 1200 drilling cycles; the specific service life depends on the stratum hardness and operational standards.
Q: Can non-standard specifications of Tapered Chisel Bit be customized?
A: Customization of cutting edge width, overall length (within the range of 150mm-400mm), and taper angle is supported, and specific engineering parameters need to be provided.
