Sealey HSS Jobber Drill Bit

The 1mm Sealey HSS Jobber Drill Bit is the smallest size in the professional range, ideal for precision drilling applications where fine, accurate holes are required. This pack of 10 fully ground bits is perfect for delicate work in electronics, jewellery making, or precision engineering. Manufactured to DIN 338 standards with a 135° split point that's self-centring, these bits reduce thrust and heat whilst ensuring accurate penetration. The efficient swarf clearance prevents clogging during extended use. Suitable for both hand and pillar drills, particularly effective on high carbon steels and copper.
