Ways to improve the service life of ball tooth bits
Release time:2025-08-05
View volume:
Ball tooth bits are increasingly used in mining, railway, hydropower, and geological industries due to their high rock breaking efficiency, effective elimination of blind zones at the bottom of rock holes, avoidance of repeated crushing of rock debris, coarse crushed rock powder particle size, and improvement of worker safety conditions. The service life of ball tooth bits is directly related not only to their structure, material, and processing quality, but also to rock properties, rock drill type, oil pressure, sharpening, and the skill level of the rock drill operator. This paper briefly discusses methods for improving the service life of ball tooth bits from the aspects of material selection, product design, processing technology and quality control, and product use.
