Faithfull FAIQC400C HSSE M35 Cobalt Quick-Change Impact Drill Bit 4.0mm OL91mm WL43mm

Faithfull Cobalt Quick-Change Impact Drill Bits feature a revolutionary tip design with 7 cutting edges and 3 peaks, offering super-accurate self-centering, fast cutting, and extended tool life. The protruding centre tip acts as a pilot to enable precise positioning and prevent wandering. Made from M35 HSSE steel with 5% cobalt content for increased heat resistance, these bits are impact rated and equipped with a 1/4-inch quick-change shank for use in impact drivers. They are produced to high-precision tolerances and geometric accuracy in accordance with DIN 338 and DIN 3126-E6.3, and are suitable for heavy-duty industrial work across a range of tough materials, including alloy and carbon steels, cast iron, hardened alloys, stainless steels, high-temperature alloys, titanium alloys, high-strength steels, and carbon fibre composites. The design aims to deliver high precision and a clean finish with fewer burrs compared to typical drill bits.
