Sealey Worksafe HSS Twist Drill Bit

The Sealey Worksafe HSS Twist Drill Bit Ø3.5mm provides a useful intermediate diameter for specific engineering applications. Supplied as a single drill bit, the 3.5mm size is particularly valuable for creating clearance holes for small self-tapping screws, pilot holes before threading, and applications where standard 3mm or 4mm sizes don't provide the optimal fit. This size is frequently specified in furniture assembly, light fabrication, and precision engineering where exact clearances matter for proper assembly and function.
