Drill bit Abraboro HSS-R 2.2 x 53 mm, metal drilling, pack of 10

Abraboro HSS-R 2.2 x 53 mm drill bit is a general-purpose high-speed steel cutting tool designed for drilling small, precise holes in metal. Supplied as a pack of 10, this set targets routine workshop and maintenance tasks where repeatable, accurate hole sizes are required. The bit’s dimensions (2.2 mm diameter, 53 mm overall length) make it suitable for thin to medium-thickness steel, cast iron and a range of non-ferrous metals; it is intended for use with hand-held and benchtop drills at appropriate speeds for HSS-R tooling.

Advantages

The HSS-R material provides good hardness and wear resistance for general metalworking, enabling consistent cutting performance on ferrous and non-ferrous materials. The small 2.2 mm diameter delivers fine, accurate holes with minimal burr when used with correct pilot and clamping, while the 53 mm length gives sufficient reach for shallow to moderate-depth drilling. Supplied in a pack of 10, the set offers multiple replacements for production runs or maintenance schedules and is compatible with standard drill chucks.

Suitable for

• Drilling small-diameter holes in thin and medium-thickness steel
• Workshop maintenance and light fabrication
• Preparing holes in cast iron and non-ferrous metals such as aluminium and brass
• Repeated small-batch production or repair jobs requiring identical hole sizes

Key specifications

• Material: high-speed steel (HSS-R)
• Diameter: 2.2 mm
• Overall length: 53 mm
• Pack quantity: 10 pieces
• Suitable tool: handheld and bench drills with standard chucks
• Typical application: metal drilling (ferrous and non-ferrous)

How to use

Secure the workpiece firmly in a vise or using clamps to prevent movement. Select an appropriate drill speed for HSS-R and the workpiece material — higher speeds for non-ferrous metals and lower speeds for harder steels. Centre-punch the drilling location for accuracy, then start drilling with moderate, steady feed pressure. Use cutting fluid or coolant when drilling tougher steels to extend tool life and reduce heat. Withdraw the drill occasionally to clear chips and avoid clogging; replace the bit when wear visibly affects hole quality.

Usage recommendations

For best results, use the Abraboro HSS-R 2.2 x 53 mm drill bit with correct clamping, appropriate speed settings and cutting fluid when working with harder ferrous metals. Store the spare bits in a dry place to prevent corrosion and inspect tips before use to ensure clean cutting edges.
