Drill bit Abraboro HSS conical 24.0 mm AB44524000

Abraboro HSS conical drill bit 24.0 mm (AB44524000) is a precision tool designed to create or enlarge tapered and conical holes in a range of materials. Manufactured from high-speed steel (HSS), this conical bit combines hardness and toughness for cutting performance on metal and general-purpose materials. The conical profile enables controlled step drilling, deburring and chamfering in one operation when used with an appropriate drill or drill press.

Advantages

The HSS construction provides heat resistance and durability under typical drilling conditions, while the conical geometry allows progressive material removal and precise control of hole diameter. The single-piece design reduces vibration and improves runout accuracy compared with multi-component tooling. The bit is suitable for repeated use with cutting fluid to extend tool life and maintain cutting performance.

Suitable for

• Creating tapered or stepped holes in metal and general-purpose materials
• Enlarging existing holes to a conical profile
• Deburring and chamfering hole entries and exits
• Use in handheld drills and drill presses with appropriate fixture or support

Key specifications

• Tip diameter: conical profile up to 24.0 mm
• Material: high-speed steel (HSS)
• Geometry: conical/tapered cutting profile for progressive drilling
• Intended use: metalworking and general-purpose drilling tasks
• Compatibility: suitable for standard drill chucks and drill presses

How to use

Secure the workpiece with a clamp or vice and align the drill axis with the intended hole center. Mount the conical bit in a suitable drill chuck ensuring minimal runout. Select an appropriate cutting speed for the workpiece material and apply cutting fluid as needed to reduce heat and improve chip evacuation. Advance the bit steadily, allowing the conical geometry to remove material progressively; withdraw occasionally to clear chips when drilling deep or when cutting softer metals. After completing the hole, deburr edges if necessary.

Usage recommendations

For best results use moderate speeds for steel and higher speeds for softer non-ferrous metals; always use appropriate cutting fluid for ferrous materials and inspect the bit for wear before repeated use. Ensure the drill is rigidly supported to minimise runout and achieve accurate conical holes.
