Faithfull Cobalt Quick-Change Impact Drill Bits are designed to deliver superior performance and durability for various heavy-duty industrial applications. These drill bits feature a revolutionary tip design with seven cutting edges and 3 peaks, providing super-accurate self-centring. They allow you to make a hole in a round pipe with one hand. They are twice as fast as split-point drill bits and offer up to 10 times longer life in mild steel, making them a cost-effective choice for professionals.Manufactured from M35 HSSE grade steel with a 5% cobalt content, these drill bits offer increased heat resistance and exceptional cutting performance, leaving fewer defects (burr) than other drill bits. The protruding centre tip acts like a pilot drill, ensuring precise positioning and preventing the drill from wandering. These impact-rated bits feature a 1/4in quick-change shank for use with impact drivers and are manufactured to DIN 338 & DIN3126-E6.3 standards for high precision tolerances and geometric accuracy.Ideal for use on alloy steels, carbon steels, cast iron, hardened alloy steels, stainless steels, high-temperature alloys, titanium alloy, high-strength steel, and carbon fibre composite materials, these drill bits are perfect for professionals seeking reliability and efficiency on the job.Included Sizes: 2,2.5,3,3.5,4,5,6 & 8mm
