Drill bit Abraboro VULCANO HSS-G DIN 338 with stepped point Ø3.2 mm

Solid high-speed steel (HSS-G) drill bit Abraboro VULCANO with stepped point, nominal diameter 3.2 mm, manufactured to DIN 338. The stepped/centering point improves initial positioning and reduces walking on the workpiece, making this drill bit suitable for general metalworking tasks. It is intended for drilling steel and non-ferrous metals and can be used in hand drills and drill presses for pilot holes and through holes where accurate alignment and consistent chip evacuation are required.

Advantages

The Abraboro VULCANO HSS-G drill bit combines a hard, wear-resistant HSS material with a stepped point geometry for improved centering and reduced walking. Its conformity to DIN 338 assures standardised shank and flute geometry for compatibility with common drill chucks and holders. The 3.2 mm diameter offers a balance between rigidity and precision for small to medium metal-drilling operations.

Suitable for

• Drilling pilot holes in steel and non-ferrous metals
• Through holes where accurate alignment is required
• Use in portable hand drills and bench drill presses
• General metal fabrication, repair and maintenance tasks

When it may not be suitable

This HSS-G solid drill bit is not intended for drilling hardened steels above typical HSS capabilities, high-alloy heat-treated materials or abrasive composites where carbide or coated drills would perform better. It is also not designed specifically for masonry, wood-optimised drilling or plastic-specific geometries.

Key specifications

• Material: High-speed steel (HSS-G)
• Point type: Stepped / centering point
• Standard: DIN 338
• Nominal diameter: 3.2 mm
• Intended use: Metal drilling (steel, non-ferrous metals)
• Suitable machine types: Hand drill, drill press

How to use

Secure the workpiece and mark the drilling position. Fit the HSS-G drill bit with the DIN 338 shank into the chuck and tighten securely. Start at low speed to use the stepped point for precise centering, then increase speed as appropriate for the material being drilled. Use cutting lubricant when drilling steel to extend tool life and improve chip evacuation. Clear chips periodically and cool the bit as needed to avoid overheating.

What to consider before purchase

• Confirm the 3.2 mm diameter fits the required hole size or pilot-hole specification
• Verify compatibility of your drill chuck with a DIN 338 shank
• Consider material hardness of the workpiece; use carbide or coated drills for very hard or abrasive materials
• Plan for appropriate speeds and cutting fluid for metal drilling

Usage recommendations

For best results when drilling steel, use a suitable cutting lubricant, moderate feed, and start at low rpm to benefit from the stepped point's centering action. Replace the bit when wear degrades cutting performance or centering accuracy.
