Drill Bit Abraboro HSS cylindrical 2.8 mm set of 10 (AB00010280)

Abraboro HSS cylindrical 2.8 mm drill bit set of 10 provides a compact collection of straight-shank high-speed steel bits designed for drilling small, precise holes in metal. Each bit in this set measures 2.8 mm in diameter and is intended for use in hand drills and drill presses. The bits are manufactured from HSS material to maintain hardness and cutting performance when working with various ferrous and non-ferrous metals, making them suitable for routine metalworking, maintenance, and light fabrication tasks.

Advantages

The HSS composition ensures good wear resistance and heat resistance compared with standard carbon steel bits, enabling stable drilling at moderate speeds. The cylindrical (straight) shank design allows secure clamping in common drill chucks without the need for adapters. Supplied as a set of ten identical diameter bits, this pack reduces downtime by providing multiple replacements and supports consistent hole size across repetitive tasks.

Suitable for

• Drilling precision small-diameter holes in sheet metal and thin plates
• Repair and maintenance tasks that require repeatable 2.8 mm holes
• Light fabrication, model making, and assembly work involving metal components
• Use with hand drills and bench drill presses

Key specifications

• Bit diameter: 2.8 mm
• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight) shank for standard drill chucks
• Quantity in set: 10 identical bits
• Intended application: metal drilling (ferrous and non-ferrous)

How to use

Select an appropriate drilling speed for the metal type and thickness, secure the workpiece, and clamp the 2.8 mm HSS bit firmly in the drill chuck. Use gradual feed pressure and allow the bit to cut without forcing; apply cutting fluid or lubricant when drilling harder metals to reduce heat and improve chip evacuation. For repeated holes, check bit condition regularly and replace bits from the set as they wear to maintain hole quality.

Usage recommendations

Use medium to high spindle speeds for non-ferrous metals and moderate speeds for hardened or thicker steel. Apply cutting fluid for stainless steel and other hard alloys. Inspect bits for wear or chipping before precision work and keep spare bits from the set readily available to maintain consistent results.
