Product Description

The DHD340A-115 DTH drill bit features a hybrid cutting structure that combines premium tungsten carbide buttons with strategically embedded PDC cutters. Unlike conventional DTH drill bits, the embedded PDC cutters reinforce the gauge area, reducing peripheral wear and helping maintain accurate hole diameter throughout long drilling cycles.

The concave face design improves drilling stability while the dome and front semi-ballistic carbide buttons deliver efficient impact energy for fast and reliable rock breaking. This optimized structure provides consistent penetration, minimizes bit wear, and enhances overall drilling efficiency in demanding quarrying and mining environments.

Designed for medium-hard to hard and abrasive formations, the DHD340A-115 offers reliable performance, lower operating costs, and extended service life for contractors requiring dependable production drilling solutions.
