Mitsubishi Diaedge Button Bits | Cross Bits | DTH Bits | For Mining, Quarrying & Infrastructure
Drilift is the authorized GCC distributor for Mitsubishi Diaedge rock drilling tools — supplying rock drilling bits for Top Hammer and DTH (Down-The-Hole) drilling in mining, quarrying, and construction projects across the GCC, Middle East, Africa, and Southeast Asia. Mitsubishi Diaedge carbide is engineered for superior hardness and wear resistance, delivering longer bit life and faster penetration rates in hard and abrasive rock conditions.


Spherical carbide button inserts pressed into a steel bit body. The most widely used bit type for production drilling in mining, quarrying, and infrastructure. Available in multiple button configurations (flat, ballistic, semi-ballistic) matched to different rock types.
Chisel-style carbide cutters arranged in a cross pattern. Used in softer rock and for smaller hole diameters.
Drill bits for DTH hammer systems, where the hammer is positioned directly behind the bit in the hole. Used for larger diameter holes and deeper drilling in hard rock where Top Hammer energy loss becomes significant.


Carbide grade is the most critical factor in drill bit performance. Mitsubishi Diaedge’s proprietary carbide grades are engineered for optimal hardness-to-toughness balance for specific rock types — delivering longer bit life, more metres per bit, and lower cost-per-metre in hard rock mining and quarrying compared to standard carbide alternatives.
Button bits use spherical or ballistic carbide inserts for penetrating hard rock — they are the most common choice for production drilling in mining. Cross bits use chisel-style cutting edges and are typically used in softer formations or smaller hole sizes.
Top Hammer is more efficient for shallower holes (typically up to 20-30m) in moderate rock. DTH is preferred for deeper holes and very hard rock, as the hammer is at the bottom of the hole and energy loss through the drill string is minimized.
Yes. Drilift is the authorized GCC distributor for Mitsubishi Diaedge. We supply button bits, cross bits, and DTH bits from UAE stock. Contact us with your hole diameter, thread type, and rock conditions.
