Drill Bit Abraboro VULCANO HSS-G DIN 338 with Step Blade Ø10.5 mm

Abraboro VULCANO HSS-G DIN 338 drill bit with step blade and a diameter of 10.5 mm is designed for general metalworking where a straight-shank, durable drill is required. Manufactured from high-speed steel (HSS-G) and produced to DIN 338 geometry, this drill bit suits both hand-held drills and drill presses. The step-blade profile supports effective chip evacuation and consistent hole quality when drilling into a variety of ferrous and non-ferrous metals in professional and workshop environments.

Advantages

The HSS-G material provides wear resistance and heat tolerance for typical metal drilling operations. DIN 338 geometry ensures a stable straight shank and precise centring for reliable hole accuracy. The step-blade design improves chip removal, reducing clogging and allowing more consistent cutting action. This combination yields a practical balance of durability and drilling performance for routine metal fabrication and maintenance tasks.

Suitable for

• Drilling holes in mild steel, cast iron, non-ferrous metals and common alloys
• Use in hand drills and drill presses in workshops and industrial settings
• Maintenance, fabrication and general metalworking tasks requiring a 10.5 mm hole

When it may not be suitable

This HSS-G drill bit is not optimized for high-performance operations such as deep-hole drilling at high feed rates or continuous production on hard tool steels where more advanced coatings or carbide grades are required. For materials with extreme hardness, abrasive composites, or ceramic substrates, a specialized carbide or coated drill would be more appropriate.

Key specifications

• Material: High-speed steel (HSS-G)
• Geometry: DIN 338 straight-shank geometry
• Tip: Step-blade (stepped flute) design for improved chip evacuation
• Diameter: 10.5 mm
• Shank type: Straight shank suitable for standard chucks
• Typical use: General metal drilling in hand and machine tools

How to use

Mark and centre-punch the drilling location before starting. Secure the workpiece and select an appropriate cutting speed for the material being drilled; use lower speeds for harder metals and higher speeds for softer non-ferrous metals. Apply steady feed pressure while keeping the drill perpendicular to the surface. Use cutting fluid or coolant for improved tool life and chip evacuation when drilling metals, and withdraw the drill periodically in deeper holes to clear chips.

What to consider before purchase

• Confirm that 10.5 mm diameter meets your hole size requirement
• Check material compatibility—HSS-G is suitable for general metalworking but not for very hard or abrasive materials
• Ensure your drill or chuck accepts straight-shank bits and secures a 10.5 mm diameter

Usage recommendations

For best results, use cutting fluid when drilling ferrous metals, choose appropriate speeds for the material, and clamp workpieces securely. Regularly inspect the cutting edge and replace the bit when wear or chipping degrades hole quality.
