Description
Overview:
The Sealey HSS Cobalt Fully Ground Drill Bit 3mm Pack of 10 (part no. DB030CB) is a set of precision metal drill bits designed for clean, accurate holes in tough materials. Each bit is made from high-speed steel with 5% cobalt for improved heat resistance and long service life when drilling high carbon steel and stainless steel. The 3.0 mm diameter (approx. 0.12 in) suits fine holes, pilot drilling, and detailed work. A 135° split point helps self-centre the bit and reduces wander for faster starts. Manufactured to DIN 338, they are jobber length with a straight shank for standard three‐jaw chucks. Supplied in a durable high-density case to keep the ten pieces organised in the van, toolbox, or workshop.
Key Features:
- 3.0 mm diameter (approx. 0.12 in) bits supplied in a pack of 10 for consistent results across multiple holes
- High-speed steel with 5% cobalt for excellent wear resistance and hot hardness on tough alloys
- Fully ground flutes for accurate sizing and smooth cutting performance
- 135° split point for self-centering starts and reduced walking on curved or hard surfaces
- Efficient swarf clearance to help prevent clogging and overheating during deeper cuts
- Straight shank fits common three‐jaw chucks on cordless drills, corded drills, and drill presses
- Built to DIN 338 for reliable dimensions and jobber-length versatility
- Suitable for stainless steel and high carbon steel; also performs well on mild steel and many non-ferrous metals
- Robust high-density storage case for easy identification and safe transport
- Professional quality suited to workshop, site, and DIY use
Typical Applications:
General metal fabrication, sheet metal work, machinery maintenance and repair, automotive and agricultural tasks, drilling holes for fasteners and rivets, pilot holes before tapping, and panel work on stainless and high carbon steel.
