Features Adapted for SDS-PLUS Rotary Hammers. Premium range. Best in its class For more productivity and accuracy. Solid Type TCT For maximum impact and torsion forces as well as prolonged service life. Shorter Entrance The drilling dust travels quickly from the drill head into the spiral flute. Rebar Chamfer This leads to an increased lifetime and optimum drilling behavior in reinforcement strikes. Shoulder Two elevations on the cutting edge, provide improved braking performance in concrete and optimal reinforcement strength. Innovated Flute Geometry the drilling dust is removed faster, while at the same time ensuring low-vibration drilling and a high degree of fracture safety. Wearing Mark Wearing mark serves as an indication of the life of the drill bit. and a high degree of fracture safety.
