Products Description
Engineered with cross-shaped carbide cutting heads, tapered cross bits deliver fast, aggressive penetration in hard rock. Their optimized design ensures efficient chip removal and strong wear resistance, making them a top pick for mining, quarrying, and construction blast hole drilling tasks.
KATDRILLS taper Cross bits
With the top quality of alloy steels and the best carbides
The tapered cross bit uses a brazing process to make the carbide installation more secure.
Vacuum heat treatment process increases wear resistance and extends service life.
Brazing technology allows hard alloys to be bonded more firmly.
Parameters
| Tapered degree | 4°46′, 6°, 7°, 11°, 12° |
| Bit diameter | 30mm - 57mm |
| Shank sizes | Hex. 19mm, Hex. 22mm, and Hex. 25mm |
Tapered cross bits are engineered for high-intensity rock drilling tasks, with key applications including:
Mining & Quarrying: Drilling precision blast holes to fragment hard rock for mineral and aggregate extraction
Tunneling: Supporting safe, efficient excavation of highway, railway and hydroelectric tunnels
Construction & Civil Engineering: Drilling anchor and foundation holes in tough rocky ground, enabling smooth site preparation
Features
Aggressive Drilling Power: Cross-configured carbide cutting heads deliver fast penetration in hard rock.
Efficient Chip Removal: Streamlined design clears rock debris quickly to prevent bit jamming.
Superior Durability: Wear-resistant carbide construction extends service life in abrasive conditions.
Precision Drilling: Excellent centering performance ensures straight, accurate blast holes.
Cost-Effective Compatibility: Works seamlessly with standard taper drill rods, reducing equipment costs.
