Durability in Concrete - The SDS plus-3 Drill Bit offers durability when drilling in concrete. To prevent heat development, the 4-flute dura design provides effective dust removal for increased endura more→nce. It is made of high-alloy steel, which is produced with an optimised hardening technology to withstand wear. For additional resistance, indented cutting edges are made from an ideal Bosch-controlled carbide blend. The bit is intended for work on concrete and masonry and is to be used with rotary hammers with SDS plus holders. As proof of quality, the drill bit bears the test mark of the PGM Masonry Drill Bit Association Board, guaranteeing compliance with tight tolerances, exact drilling and …

Maximum Precision - The HSS Twist Drill Bit Ground is for drilling through metal with maximum precision. The bit's exposed 135-degree self-centring split-point tip combines active cutting and perfect more→centring without wandering, delivering maximum precision. The split-point tip also eliminates any need to pre-punch or pilot drill for up to 10 mm. This precision-ground bit made of HSS (high-speed steel) enables up to 40% faster drilling rate and up to 50% lower feed pressure than standard-ground HSS drill bits with chisel edges. This bit is designed for drilling holes in alloyed and non-alloyed steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals and hard plastics.…
