DTH Bits
Torquato Drilling Accessories' down-hole hammer bits are designed for quarry, mining, construction and water well projects. A full line of bits ranging in size from 3 5¿inches thru 42 inches for use with most of the popular hammers is available. In addition to precision manufacturing, the bits are subjected to several processes to help ensure consistent performance. These processes include thru-hardened/double tempered heat treatment for strength throughout. In addition, all bits are "shot-peened" (a stress-relieving process) on both inside and outside services to add further durability. Torquato Drilling Accessories
