Breaker Points. 3 offset aggressive power breakers. These produce a "Demolition" effect and create micro cracks in the drilled material. Up to 25% FASTER. Centering tip. Ensures immediate spot drilling with pin point accuracy. Prevents skidding on smooth surfaces. Enlarged rebar chamfers. Prevents side tip damage when hitting rebar. Reduces the risk of the drill bit jamming when hitting rebar. Tapered shoulder design. Thinner shoulder towards drill tip for less friction providing for greater speed. Ideal for cordless hammers identified from its tapered shoulder geometry. Reinforced flute. High volume flute geometry for optimum dust removal. Reinforced flute design (thicker core) gives: - Full power transfer to the tip. - Lower vibrations. - Exceptional break resistance, less breakages and best durability. Made in Germany.
