Sealey HSS Jobber Drill Bit

The 12mm Sealey HSS Jobber Drill Bit is a popular size for M12 bolt clearances, substantial fixings and heavy-duty drilling operations. This pack of 5 fully ground bits is manufactured to DIN 338 standards for precision and consistency. The 135° split point is self-centring, which helps reduce thrust, friction and heat generation whilst ensuring easier penetration into the workpiece. Efficient swarf clearance prevents clogging during continuous drilling. These bits work excellently with both hand and pillar drills, particularly on high carbon steels and copper. Each pack includes a high-density case for safe, organised storage.
