Drill bit Abraboro AB30009000 HSS-G DIN 338 stepped tip Ø9.0 mm

The Abraboro AB30009000 is a 9.0 mm solid high-speed steel (HSS‑G) twist drill manufactured to DIN 338 geometry with a stepped tip. Designed for general-purpose drilling in metals and other materials compatible with HSS drills, this 9 mm drill bit provides a consistent hole size for workshop, maintenance and industrial tasks. The stepped tip profile improves centering and penetration, while the DIN 338 geometry ensures standard helix and point angles for reliable cutting performance in hand-held and machine drills.

Advantages

This HSS‑G drill bit combines the hardness and heat resistance of high-speed steel with a stepped tip that aids initial bite and reduces walking on the workpiece. Manufactured to DIN 338 dimensional and geometric standards, it delivers predictable hole accuracy and repeatability. Its solid construction provides durability under typical workshop and maintenance loads and compatibility with a wide range of drilling setups.

Suitable for

• Drilling through mild and alloy steels
• General metalworking and fabrication tasks
• Workshop and maintenance drilling with hand-held or machine drills
• Creating 9 mm holes for fastening and assembly

Key specifications

• Material: Solid high-speed steel (HSS‑G)
• Nominal diameter: 9.0 mm
• Tip type: Stepped/graded tip
• Geometry: DIN 338 standard geometry
• Tool type: Twist drill bit
• Intended use: Metal drilling and other materials suitable for HSS

How to use

Select an appropriate cutting speed and feed for the workpiece material and secure the drill in a suitable chuck. Mark the drilling position and, if required, use a center punch to improve start accuracy. Begin drilling at a low speed to allow the stepped tip to engage, then increase speed to the recommended range for HSS in the specific material. Use cutting fluid when drilling steels to reduce heat and extend tool life. Withdraw the drill periodically to clear chips in deeper holes.

Usage recommendations

For best results when drilling steels and harder alloys, use appropriate cutting lubricants, moderate drilling speeds, and steady feed pressure. Inspect the bit for wear or damage before use and replace when the tip becomes rounded or produces poor hole quality.
