Drill bit Abraboro VULCANO HSS-G DIN 338 with stepped tip Ø6.5 mm

Abraboro VULCANO HSS-G DIN 338 drill bit with a stepped tip and 6.5 mm diameter is a solid high-speed steel tool designed for general metalworking and workshop tasks. The DIN 338 geometry provides a robust conical profile with a stepped (tiered) point that helps to improve centering on the workpiece and facilitates chip evacuation during drilling. The HSS-G material offers wear resistance and heat tolerance appropriate for drilling through a range of ferrous and non-ferrous metals using hand-held drills and drill presses.

Advantages

The stepped tip improves initial centering and reduces walking on flat or round surfaces, while the DIN 338 geometry ensures a stable cutting profile and consistent hole quality. Made from solid high-speed steel, the bit provides resistance to abrasion and thermal softening under normal workshop drilling conditions. The 6.5 mm diameter is a common size for mechanical and maintenance applications, offering a balance between rigidity and cutting efficiency.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminium and other common metals
• Use in hand-held drills and bench or pillar drill presses
• General maintenance, fabrication and workshop repair tasks
• Pre-drilling for tapping or fastening operations

Key specifications

• Material: solid high-speed steel (HSS-G)
• Geometry: DIN 338 with stepped (tiered) point
• Diameter: 6.5 mm
• Cutting tip: stepped for improved centering and chip control
• Suitable machine types: hand drills, bench/pillar drill presses

How to use

Secure the workpiece and select an appropriate drilling speed for the material being worked—lower speeds for harder steels and higher speeds for softer metals such as aluminium. Clamp the drill bit firmly in the chuck and align the stepped tip with the marked drill point. Apply steady, moderate pressure and allow the bit to cut without excessive force; withdraw periodically for chip clearance when drilling deeper holes. Use cutting fluid for improved tool life and cooling when working with steel or stainless steel.

Usage recommendations

To extend tool life and achieve accurate holes, use appropriate cutting speeds and lubricants, ensure correct clamping of both bit and workpiece, and replace the bit if signs of wear or chipping appear on the cutting edges.
