Product Description

43mm Diameter 7° Taper Angle High Hardness Chisel Bit For Rock Drilling

Our 43mm 7 degree tapered chisel bits are premium rock drilling tools engineered for high efficiency rock penetration in mining and quarrying projects. Manufactured by professional rock drill bit factories, this series features precise dimensional standards, sturdy structural stability and outstanding wear resistance, serving as a cost-effective drilling solution for diverse hard rock working conditions.

Core Technical Parameters

Bit Diameter : 43mm
Taper Angle : 7°
Shank Specification : H25*108mm
Overall Height : 67mm

Applications

This tapered chisel bit is versatile for various mining and stone processing operations including:

Ferrous metal mines (iron and manganese mines)
Non ferrous metal mines (gold, silver, and copper mines)
Marble and granite quarrying

For hard rock with hardness grade F8 - F14, the bit supports maximum drilling depth of 15 -18 meters. It perfectly matches light duty handheld rock drills like Y6, Y10 and Y24 models, focusing on shallow hole drilling within 5 meters depth and 20 - 45mm hole diameter.

Ideal for natural stone quarrying applications including small hole drilling, stone block trimming and secondary splitting of small rock blocks.

Compatible with hexagonal 25mm and 12mm tapered drill rods with 4°, 6°, 7°, 11° and 12° taper angles, featuring strong adaptability for conventional drilling equipment.

Performance Quality

Adopting high purity raw materials and professional precision heat treatment technology, our tapered chisel bits deliver exceptional hardness, impact resistance and durability.

The integrated carbide insert design ensures stable cutting performance, effectively avoiding edge collapse and abrasion during continuous high intensity drilling.

We maintain sufficient stock and stable production capacity, enabling flexible and fast delivery to fully meet customers' bulk order and urgent delivery demands.

With reliable quality and competitive cost performance, our drill bits have won long-term recognition from global mining and quarrying industry clients.
