Drill Bit Abraboro AB30010000 HSS-G DIN 338 step drill 10.0 mm

Abraboro AB30010000 is a 10.0 mm HSS‑G straight‑shank drill produced to DIN 338 with a stepped cutting tip. Made from high‑speed steel, this drill bit features standard geometry suitable for drilling holes in steel and similar ferrous materials. The stepped tip improves centring and chip evacuation during through‑drilling operations, making it appropriate for use in drill presses and stationary drilling machines in workshops and industrial environments.

Advantages

The HSS‑G material provides hardness and heat resistance appropriate for general metalworking. DIN 338 straight‑shank construction ensures accurate runout and compatibility with standard chucks and holders. The stepped cutting tip supports reliable centring and reduces walking on the workpiece, while the 10.0 mm diameter offers a common size for through‑holes and clearance holes. Overall, the design balances durability, machining stability, and ease of use for routine drilling tasks in steel and similar materials.

Suitable for

• Drilling through mild and medium‑hard steel
• General metalworking and maintenance tasks in workshops
• Use in drill presses and stationary drilling machines
• Creating clearance and through‑holes for fastening and assembly

Key specifications

• Material: high‑speed steel (HSS‑G)
• Shank type: straight shank, DIN 338 geometry
• Tip type: stepped cutting tip for improved centring
• Diameter: 10.0 mm
• Intended use: metalworking / drilling in steel and similar materials

How to use

Secure the workpiece and select appropriate clamping to prevent movement. Install the 10.0 mm HSS drill in a compatible chuck, ensuring correct alignment and tight clamping. Use cutting fluid or coolant when drilling into steel to reduce heat and extend tool life. Start drilling at a moderate speed suitable for the material hardness, apply steady feed pressure, and allow the drill to clear chips periodically. Retract the drill occasionally on deep holes to improve chip evacuation.

Usage recommendations

For best results when drilling steel, use recommended cutting speeds and lubrication for HSS drills, maintain a stable machine setup, and replace the drill once wear affects centring or cutting performance.
