Drill bit Abraboro HSS cylindrical for metal 14 mm (AB00011402)

Abraboro HSS cylindrical drill bit for metal, 14 mm diameter, is designed for drilling clean through-holes and general metalworking tasks. Made from high-speed steel (HSS), the straight-shank geometry fits hand drills and drill presses and provides consistent cutting performance when working with ferrous and non-ferrous metals. The bit is intended for workshop use, maintenance, and fabrication where precise, reliable holes are required.

Advantages

The HSS material offers good hardness and heat resistance for prolonged cutting life under moderate drilling speeds. A straight cylindrical shank ensures secure clamping in standard chucks, while the 14 mm diameter provides a common size for structural and assembly holes. The geometry is optimised for through-holes, delivering accurate hole diameter and a smooth surface finish when used with appropriate cutting speeds and lubrication.

Suitable for

• Drilling through ferrous metals such as steel and cast iron
• Drilling non-ferrous metals including aluminium, brass, and copper
• Hand drills and drill press applications in workshops
• Maintenance, repair, and fabrication tasks requiring 14 mm holes

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight shank)
• Tip: standard twist point designed for through-holes
• Diameter: 14 mm
• Typical applications: metal drilling for ferrous and non-ferrous materials

How to use

Secure the drill bit in the chuck of a hand drill or drill press, ensuring the shank is fully seated and tightened. Select an appropriate spindle speed and feed rate for the workpiece material; lower speeds are recommended for harder ferrous metals. Use cutting fluid or lubricant when drilling metals to reduce heat, improve chip evacuation, and prolong tool life. For precise through-holes, clamp the workpiece firmly, pilot-drill if needed, and back the bit out periodically to clear chips.

Usage recommendations

For best results, match cutting speed to the specific metal being drilled, apply cutting lubricant for improved finish and tool life, and ensure stable clamping. Inspect the bit before use for damage or wear and replace it when edges become dull to maintain hole accuracy and safety.
