Drill Bit Abraboro HSS Conical 23.5 mm AB44523500 for Metal

Abraboro HSS Conical 23.5 mm AB44523500 for Metal is a high-speed steel conical drill bit designed specifically for drilling and enlarging holes in metal. The conical geometry allows progressive cutting and controlled material removal, while the HSS material offers wear resistance and heat tolerance during extended use. This tool is suitable for use with both hand-held drills and drill presses in metalworking, repair and fabrication environments.

Advantages

The conical profile enables gradual hole enlargement and effective deburring in a single operation, reducing the need for multiple tools. Made from high-speed steel, the bit maintains cutting performance and edge stability under elevated temperatures and friction typical of metal drilling. Its geometry promotes stable centring and consistent chip evacuation for cleaner holes and longer tool life.

Suitable for

• Enlarging and deburring holes in steel and non-ferrous metals
• Metal fabrication and repair work
• Use with hand drills and bench drill presses
• Progressive hole sizing without switching cutters

Key specifications

• Material: High-speed steel (HSS)
• Shape: Conical / step-style profile for gradual enlargement
• Working diameter: 23.5 mm
• Intended material: Metal (ferrous and selected non-ferrous alloys)
• Typical applications: Drilling, hole enlargement, deburring

How to use

Secure the workpiece firmly in a vise or clamping fixture to prevent movement. Select an appropriate rotational speed for metal drilling—moderate speeds reduce heat buildup with HSS tools. Apply cutting fluid or lubricant to improve chip evacuation and reduce wear. Start the hole using a pilot or existing hole if available, then feed the conical bit steadily into the workpiece with consistent pressure until the required diameter is reached. Retract periodically to clear chips and reapply lubricant if necessary.

Usage recommendations

For best results, use steady feed rates and appropriate cutting fluid when working with steel; reduce speed for harder alloys and increase speed slightly for softer non-ferrous metals. Inspect the bit for wear before use and replace if the cutting edges show significant bluntness to maintain hole quality and safety.
