Button Bit Regrinding System

DKI brings grinding technology to the rock face, offering a high quality, low cost comprehensive re-sharpening system enabling operator’s ease of use and maintenance whilst maximizing the efficiency of the drill bits. To obtain the optimum performance from your rock drilling equipment, it is essential that the profile of your cemented carbide drill bit inserts is maintained to the correct standard.

Failure to regrind your rock drill at regular intervals can result in dramatic loss of penetration rate and tendency for hole deviation or, at worse, irreparable damage to the drill.


DKI’s Stabilizers are designed to keep the drill string centered in the hole, by reducing sidetracking and vibrations. Available in a variety of options such as Smooth & Straight/Spiral Blade body.

Fishing Tools

DKI offers a full range of high-quality fishing tools such as taper taps, overshots & magnets, that are used to retrieve lost, damaged and/or stuck in the hole tooling.

Rock Drill Oil

DKI’s Eco-Lube is a high-performance rock drill lubricant, designed to maximize lubricity and wear protection under extreme pressures, when used in automatic oiling systems. The LOW-VISCOSITY FORMULA ensures that the lubricant is efficiently atomized into the air stream to coat and protect moving parts and seals.

ECO-LUBE is Environmentally Safe, Petroleum Free and readily biodegradable.
