## Summary description

Conical Abraboro HSS drill bit for metal with a 21.0 mm diameter, designed for cutting and enlarging holes in steel and other ferrous and non-ferrous metals.

## Long description

The Abraboro HSS conical metal drill bit 21.0 mm is a high-speed steel cutting tool designed for enlarging and countersinking holes in ferrous and non-ferrous metals. Its conical geometry provides progressive cutting action that reduces chatter and helps maintain concentricity when drilling with drill presses and handheld drills. Manufactured from high-speed steel, the bit offers wear resistance and sustained cutting performance under typical metalworking conditions.
Advantages
The conical shape enables smooth stepwise material removal and precise hole enlargement without the need for multiple straight bits. High-speed steel construction ensures thermal stability and resistance to abrasive wear during repeated use. The bit is compatible with standard drill chucks and can be used in both stationary and portable drilling equipment, offering versatility across fabrication, repair, and maintenance tasks.
Suitable for
Enlarging pre-drilled holes in steel and other metals
Countersinking and deburring metal edges
General metal fabrication and maintenance work
Use with drill presses and handheld drills
Key specifications
Diameter: 21.0 mm
Material: High-speed steel (HSS)
Geometry: Conical/step drill profile for progressive cutting
Intended materials: Ferrous and non-ferrous metals
Compatibility: Standard drill chucks, drill presses, handheld drills
How to use
Secure the workpiece to prevent movement and select a suitable pilot hole if progressive enlargement is required. Fit the conical drill bit into the drill chuck and tighten securely. Use appropriate cutting speed and moderate feed pressure; reduce speed for thicker or harder materials to avoid overheating. Apply cutting fluid or lubricant as needed to improve chip evacuation and extend tool life. Withdraw the bit periodically to clear chips and allow cooling.
Usage recommendations
For best results, start with a smaller pilot hole and increase diameter gradually using the conical profile. Use cutting oil when drilling steel and maintain steady speeds to preserve edge life. Inspect the bit for wear and resharpen or replace when performance declines.
