Sealey Worksafe HSS Twist Drill Bit

The Sealey Worksafe HSS Twist Drill Bit Ø4.5mm offers a specialist intermediate diameter for precision engineering work. Supplied as a single drill bit, the 4.5mm size is commonly required for pilot holes before tapping M6 threads, creating clearance for specific screw types, and applications where standard sizes provide insufficient precision. Engineers and fabricators value this size for tolerance-critical assembly work, particularly in automotive repair, machinery maintenance, and bespoke metalworking projects where exact specifications must be met.
