Description
Overview:
The Addax HSS Cobalt Jobber Drill, 4.5mm diameter and 80mm overall length, is a robust bit for precision drilling in hard and abrasive metals. Manufactured from cobalt-alloy high-speed steel and made to DIN 338, it delivers reliable performance under heat and load. Its jobber-length design suits everyday drilling tasks on construction and garden machinery, whether you're working with stainless steel or chromium-nickel alloys. The straight shank fits standard 3‐jaw chucks on cordless drills, corded drills, and pillar drills, making it a practical choice for workshop and site use. Roll-forged construction provides consistent geometry and strength. This bit offers a clean cut with reduced wear, helping maintain accuracy and surface finish over repeated jobs. Manufacturer Part Number: 902 0620.
Key Features:
- Cobalt-alloy HSS for high heat resistance and long tool life in tough metals
- Roll forged for strength, concentricity, and consistent drilling performance
- DIN 338 compliant for jobber-length sizing and reliable quality control
- 4.5mm diameter for clearance and pilot holes common in steel fabrication and maintenance
- 80mm overall length for good reach while staying stable in handheld drills
- Straight shank compatible with standard 3‐jaw chucks across most drills
- Suitable for stainless steel and Cr-Ni alloys where ordinary HSS struggles
- Resists edge softening at elevated temperatures to reduce premature dulling
- Smooth cutting action helps produce accurate holes with minimal burring
- Works well with cutting fluid to improve finish and extend service life
Typical Applications:
General metalworking, fabrication, and maintenance on machinery frames, brackets, guards, and fixings. Ideal for drilling stainless fasteners, panels, and box section in construction and agricultural equipment. Useful for workshop repair tasks, site installations, and manufacturing jobs where reliable hole sizing and durability are required in hard steels and alloys.
