43mm Diameter 7° Tapered Cross Bit With Hexagonal Shank For Mining And Quarry Drilling

Henglong high performance tapered cross bits are professionally engineered for rock drilling operations, widely applicable to ferrous and non ferrous metal mines, as well as natural stone quarrying projects. Adaptable to iron, manganese, gold, silver, copper mines and granite, marble and other stone materials, these drill bits deliver stable and efficient drilling performance for diverse geological conditions.

Optimized for medium and high hardness rock layers with a hardness grade of F8 - F14, the bits support a conventional drilling depth of 15m to 18m for deep mining operations. Meanwhile, they are perfectly suited for shallow drilling work within 5 meters deep with a drilling diameter ranging from 20mm to 45mm. Compatible with light duty handheld rock drills including Y6, Y10 and Y24 models, they are ideal for stone quarry hole drilling, block trimming and secondary splitting of small stone blocks.

This series of cross bits adopts a standard hexagonal shank design of 25×108mm, with a 7° taper degree and optional overall heights of 67mm or 78mm (including carbide inserts). It can perfectly match 25mm and 12mm hexagonal tapered drill rods with 4°, 6°, 7°, 11° and 12° taper angles, featuring strong compatibility and flexible assembly.

Manufactured with premium raw materials and precision special heat treatment technology, our tapered cross bits boast excellent wear resistance, impact resistance and long service life. Supported by sufficient factory inventory and reliable production capacity, we can fully meet customers' bulk order and urgent delivery demands, providing cost effective and durable rock drilling consumables for global mining and quarrying clients.
