Draper Expert HSS Cobalt Drill Bit

The 7.5mm Draper Expert HSS Cobalt Drill Bit provides reliable performance for medium-duty drilling across metalworking and engineering applications. This popular size is commonly specified for bolt clearance holes and mechanical fastening applications, whilst the 180mm overall length delivers the perfect balance between control and reach. The compact format makes it particularly suitable for work in confined spaces where longer bits would prove unwieldy. Enhanced with 5% cobalt content, this high-speed steel drill bit offers superior wear resistance compared to standard HSS alternatives. The cobalt addition transforms the bit's ability to maintain its cutting edge when drilling harder materials, including stainless steel and heat-treated alloys. This translates to longer intervals between bit changes, improved productivity, and more consistent hole quality throughout the bit's extended service life.
