Description
Overview:
The Addax HSS Cobalt Jobber Drill (5.5mm diameter, 93mm overall length) is a robust metal drilling bit designed for tough materials and everyday workshop use. Made from high-speed cobalt steel (HSS-Co), it offers excellent heat resistance and wear life when drilling stainless steel and chromium‐nickel alloys, where standard HSS bits struggle. Built to the DIN 338 jobber pattern and roll forged for strength, it provides reliable performance in cordless drills, mains-powered hand drills, and pillar/drill presses. The 5.5mm size is widely used for clearance holes for M5 fixings, making it a handy choice for fabrication, site work, maintenance, and repair tasks. A straight shank fits standard 3‐jaw chucks for quick, secure setup and consistent, accurate drilling.
Key Features:
- 5.5mm diameter, 93mm overall length for general-purpose jobber reach
- HSS cobalt steel construction for high heat resistance and long service life
- Roll forged for superior strength and toughness under load
- DIN 338 specification for consistent geometry and quality
- Excels in stainless steel and Cr‐Ni alloys where conventional HSS can overheat
- Suitable for mild steel, cast iron, and many non‐ferrous metals (e.g. brass, copper)
- Straight shank fits standard 3‐jaw drill chucks for easy, secure fitting
- Clean, accurate drilling with reduced risk of work hardening in difficult metals
- Reliable choice for site work, fabrication, maintenance, and metalworking tasks
- Works with cordless drills, mains hand drills, and drill presses
Typical Applications:
Precision drilling in stainless fabrications, brackets, guards, and panels; creating 5.5mm clearance holes for M5 fasteners; workshop and site repairs on machinery, frames, and fixings; drilling in Cr‐Ni alloys, mild steel, and cast iron; general metalworking where durability and heat resistance are important. Use with suitable cutting fluid for best tool life and finish.
