Description
Overview:
The Addax HSS Cobalt Jobber Drill is a heavy-duty metal drilling bit designed for reliable performance in tough materials. With a 12.0 mm diameter and an overall length of 151 mm, it is a standard jobber-length drill suitable for hand-held drill drivers, corded drills, drill presses, and pillar drills used around construction sites and workshops. Made from high-speed cobalt steel (HSS-Co), it offers strong heat resistance and durability under sustained load. Roll-forged construction delivers toughness for everyday maintenance work on machinery, fixtures, and fabrications. Built to DIN 338 standards, it provides consistent quality and fit. Ideal for stainless steel and chromium-nickel alloys, it also performs well in mild steel, cast iron, and harder ferrous materials when used with the correct speed and cutting fluid.
Key Features:
- 12.0 mm diameter x 151 mm overall length for versatile, general-purpose metal drilling
- HSS cobalt steel for high heat resistance and long service life in difficult alloys
- Roll-forged for strength and durability under heavy use
- DIN 338 compliant for consistent geometry and performance
- Two-flute twist design for steady chip evacuation and smoother holes
- Straight, cylindrical shank compatible with standard 13 mm capacity chucks
- Suitable for cordless and corded drills, drill presses, and magnetic bases
- Performs well on stainless steel and Cr-Ni alloys when run at slower speeds
- Works on mild steel, cast iron, and other ferrous metals with appropriate technique
- Re-sharpenable tip for extended tool life when maintained correctly
- Reliable choice for on-site repairs, fabrication, and machinery maintenance
- Balanced design helps reduce wandering when starting holes on flat surfaces
Typical Applications:
Drilling bolt holes, mounting points, and clearance holes in stainless guards, brackets, frames, and plate. Repair and fabrication tasks on construction and garden machinery, including mower decks, excavator brackets, conveyor covers, and site railings. Suitable for workshop projects in mild steel and cast iron, as well as stainless kitchen, HVAC, and handrail installations when used with cutting lubricant and correct speeds.
