The Dormer A147 HSS-E Cobalt High Speed Steel Drill Bit is engineered for superior performance and durability. Constructed from HSS-E cobalt, this drill bit offers enhanced heat resistance and wear pr more→otection, ensuring extended tool life even under the most demanding conditions. Featuring a 130° split point, the A147 ensures precise and rapid starts, reducing bit walking and enhancing drilling accuracy. The cobalt content provides excellent performance when drilling through hard and abrasive materials such as stainless steel, cast iron, and titanium. Its optimised geometry facilitates efficient chip evacuation, minimising heat buildup and friction for smoother, faster drilling. Features …

Very Robust for Formwork - The Installation Drill Bit is very robust for formwork. Its drill bit and shank end are screw-connected, which ensures a low risk of breakage and improves smooth-running ope more→rations. Furthermore, its tapered flute, offset drill bit and shank ends prevent jamming even in moist wood, while maintaining enough power to cut through embedded nails. Equipped with an extra-long shank, the bit delivers versatile drilling in multilayer building materials or sandwich materials, e.g. for building trade (formwork) and for interior fitting work, plumbing, heating and electrical installation. It is suitable for use on formwork, boards, planks, beams, plasterboard, light building materials,…
