Drill bit Abraboro AB30005000 HSS-G stepped point Ø5 mm DIN 338

Abraboro AB30005000 HSS-G stepped point Ø5 mm DIN 338 is a 5 mm high-speed steel twist drill designed for general-purpose drilling in metal and other common workshop materials. The stepped (tiered) cutting point improves centring and reduces walking when starting a hole, while the DIN 338 geometry ensures consistent flute shape and cutting angles for reliable chip evacuation and prolonged tool life. This drill bit is suitable for use in both hand-held drills and machine tools where standard HSS performance and dimensional accuracy are required.

Advantages

The HSS-G material provides good wear resistance and toughness for intermittent and continuous drilling operations. The stepped point reduces the need for pilot holes by improving initial contact and prevents lateral slipping on workpiece surfaces. DIN 338 standardization guarantees uniform diameter tolerance and helix form, making the bit compatible with common chucks and drill holders. Its 5 mm diameter offers a versatile size for general metalworking, maintenance and fabrication tasks.

Suitable for

• Drilling through steel, iron and non-hardened metals
• General workshop and maintenance tasks
• Hand-held drill and bench/machine drill applications
• Fabrication, repair and assembly operations

Key specifications

• Material: high-speed steel (HSS-G)
• Tip type: stepped (tiered) cutting point
• Diameter: 5 mm
• Standard: DIN 338 geometry
• Shank type: straight round shank suitable for standard chucks
• Application: general-purpose drilling in metals and common workshop materials

How to use

Secure the drill bit in a properly tightened chuck and select an appropriate spindle speed and feed for the material being drilled. For ferrous metals, use moderate speeds and steady feed; for non-ferrous materials, increase speed as appropriate. Apply cutting fluid or lubricant when drilling steel to improve chip evacuation and reduce heat buildup. Start drilling with light pressure to allow the stepped point to centre, then apply steady, even force to maintain hole quality. Clear chips regularly and retract periodically on deeper holes to prevent clogging.

Usage recommendations

Use the Ø5 mm HSS-G stepped point drill for general metalworking tasks where accurate centring and reliable chip removal are needed; supplement with appropriate cutting fluid and matching drill speeds to extend tool life and ensure consistent hole quality.
