Description
Overview:
The Addax HSS Cobalt Jobber Drill is a 10.5mm diameter, 133mm long twist drill designed for accurate drilling in tough metals. Made from high‐speed cobalt steel (HSS‐Co), it offers strong heat resistance and edge retention, so it keeps cutting when temperatures rise. The roll‐forged construction provides toughness for demanding work on site or in the workshop. Built to DIN 338 standards, it delivers consistent size and dependable performance. The standard round shank fits most corded and cordless drills, drill presses, and pillar drills with three‐jaw chucks. Well suited to stainless steel and Cr‐Ni alloys, it is a reliable choice for maintenance, fabrication, and installation tasks. Manufacturer Part Number: 902 0635.
Key Features:
- 10.5mm diameter and 133mm overall length for general‐purpose, jobber‐length reach
- HSS‐Cobalt material for excellent heat resistance and long tool life in hard metals
- Roll‐forged for superior toughness and reduced risk of breakage under load
- Conforms to DIN 338 for reliable sizing, concentricity, and quality control
- Optimised for stainless steel and Cr‐Ni alloys; also suitable for many engineering steels
- Cylindrical shank fits standard three‐jaw chucks on hand drills and pillar drills
- Smooth cutting action helps maintain hole accuracy and clean finish
- Can be re‐sharpened to extend service life when used and maintained correctly
- Durable bronze‐coloured HSS‐Co body for easy identification in the toolbox
- Performs best at steady speeds with appropriate cutting fluid on stainless steel
Typical Applications:
Drilling stainless steel worktops, brackets, flanges, and panels; fabricating railings and frames; maintenance of plant, HVAC, and machinery; site installation of fixings and conduit. The 10.5mm size is commonly used for close‐clearance holes on M10 fixings and general fabrication where a precise 10.5mm hole is specified.
