Description

Tapered cross bits from rock drill bits, suitable for mining of black metal mines(such as iron mines, manganese, etc), nonferrous metal mine(such as gold, silver, copper, etc), marble and granite, etc. Its drilling depth usually is 15m-18m in case of hardness grade F8-14.

Widely used in light handheld drills with a depth of fewer than 5 meters and a diameter range of 20-45 mm, such as Y24 、YT27, and other handheld rock drills, mainly used for drilling small holes, trimming blocks, and secondary division of small blocks in natural three-dimensional stone quarries. Matched with hexagonal H22 mm drill rods.
The tapered cross bits are all made of high-quality raw materials with special treatment, which have strong conveying capacity and can fully meet the customer’s requirements for conveying design capacity.
