Drill bit Abraboro AB30012000 HSS-G stepped point Ø12.0 mm DIN 338

Abraboro HSS-G stepped point drill bit AB30012000 with a nominal diameter of Ø12.0 mm manufactured to DIN 338 is a general-purpose cutting tool for drilling metal and common workshop materials. Constructed from high-speed steel (HSS-G), the bit combines wear resistance with toughness for routine drilling operations. The stepped point geometry improves centring on workpieces and promotes efficient chip evacuation, making it suitable for use in both hand-held drills and drill presses in industrial and workshop environments.

Advantages

The stepped point design reduces walking and ensures precise hole starts without the need for an additional centre punch in many cases. High-speed steel construction offers a balance of hardness and toughness for steady performance when drilling mild steel, cast iron, non-ferrous metals and other standard materials. Conforming to DIN 338 provides consistent dimensions and shank fit for common drill chucks, and the geometry supports effective chip removal to maintain cutting efficiency over extended runs.

Suitable for

• Drilling through mild and medium-hard steels
• General metalworking and fabrication tasks
• Use with hand drills and bench or pillar drills
• Workshop maintenance and industrial production setups

Key specifications

• Material: High-speed steel (HSS-G)
• Nominal diameter: 12.0 mm
• Point type: Stepped point for improved centring and chip control
• Standard: Manufactured to DIN 338 dimensions
• Recommended use: Cutting of metals and common workshop materials
• Intended mounting: Compatible with standard drill chucks used on hand drills and drill presses

How to use

Select appropriate spindle speed and feed for the material being drilled; lower speeds and steady feed are recommended for harder metals. Secure the workpiece to prevent movement and, where necessary, mark the start point or use a centre punch for very accurate positioning. Use cutting fluid or coolant when drilling steel to reduce heat and extend tool life. Start drilling with light pressure until the stepped point locates, then apply uniform pressure to advance through the material.

Usage recommendations

For longer tool life and better hole quality, use appropriate cutting lubricant, avoid excessive feed rates that can cause chipping, and re-sharpen the bit when wear affects centring or cutting performance. Inspect the shank for secure mounting and remove swarf frequently to prevent clogging.
