Description
Overview:
The Addax HSS Cobalt Jobber Drill (10.2mm diameter, 133mm overall length) is a heavy‐duty metal drill bit for accurate holes in hard and abrasive materials. Made from high‐speed cobalt steel, it offers high strength and excellent heat resistance for demanding work. Built to DIN 338 jobber specifications with a straight shank, it suits most handheld drill drivers, corded drills, pillar drills, and magnetic drills. The 10.2mm size is commonly used as the tapping drill for M12 x 1.75 threads, making it useful in fabrication and maintenance. Roll‐forged construction supports consistent performance and durability when cutting stainless steel and chromium‐nickel (Cr‐Ni) alloys, as well as other tough steels, when used with suitable speeds and cutting fluid.
Key Features:
- 10.2mm diameter for precise pre‐tapping holes (ideal for M12 x 1.75) - 133mm overall length, jobber pattern for good reach and rigidity - High‐speed cobalt steel for strength and long life in tough metals - Excellent heat resistance for sustained cutting at appropriate speeds - Roll‐forged for robust geometry and reduced breakage risk - DIN 338 compliant for consistent size and shank accuracy - Straight shank fits standard drill chucks and collets - Optimised for stainless steel and Cr‐Ni alloys; also suitable for other alloyed steels - Clean hole quality when used with correct feed, speed, and coolant - Suitable for trade, workshop, site, and demanding DIY use
Typical Applications:
Drilling pilot and clearance holes in stainless fabrications, guards, brackets, and fixings; preparing tapping holes for M12 threads; workshop maintenance on plant, agricultural and garden machinery; site fitting of railings, balustrades, sheet, and plate; fabrication of exhausts, frames, and enclosures; electrical and plumbing containment work in steel trunking and cabinets.
