Drill bit Abraboro HSS conical 13.5 mm AB44513500

Abraboro HSS conical 13.5 mm AB44513500 is a conical high-speed steel drill bit engineered for general metalworking. With a 13.5 mm diameter and a tapered conical profile, this HSS bit is intended for drilling holes in mild steel, sheet metal and many common metal materials. Its high-speed steel construction offers increased wear resistance and elevated heat tolerance during continuous cutting, making it suitable for workshop and maintenance tasks. The shank is compatible with standard drill chucks and portable or bench drilling machines.

Advantages

The drill bit’s HSS material provides consistent hardness and toughness at elevated cutting temperatures, reducing premature wear. The conical geometry ensures gradual material engagement, improving centring and chip evacuation for cleaner holes. Its 13.5 mm diameter fills a common size range for metal fabrication and repair, offering a balance between hole size and drilling effort. Designed for compatibility with standard chucks, the bit is easy to install and replace.

Suitable for

• Drilling through mild steel and alloy steels
• Sheet metal fabrication and repair
• Workshop maintenance and mechanical repairs
• Portable drilling with hand-held drills and bench drills

Key specifications

• Material: High-speed steel (HSS)
• Tip profile: Conical / tapered
• Diameter: 13.5 mm
• Intended use: Metal drilling (mild and hardened steels, sheet metal)
• Compatibility: Standard drill chucks and general-purpose drilling machines

How to use

Secure the drill bit in a compatible chuck and ensure it is tightened to prevent slippage. Mark the drilling location and, where appropriate, centre-punch to improve accuracy. Use suitable cutting speed and feed for HSS in metal—moderate speeds for harder steels and higher speeds for softer metals—while applying steady pressure. Use cutting fluid or coolant on thicker or harder materials to reduce heat and extend tool life. After drilling, clear chips from the hole and inspect the bit for wear before subsequent use.

Usage recommendations

For best results, select cutting speeds and feed rates appropriate to the material being drilled and use a suitable lubricant when working with hardened steels or prolonged drilling operations; periodically check the bit for wear and replace if the cutting edges become rounded.
