Drill Bit for Metal Abraboro HSS cylindrical 3.4 mm, pack of 10 (AB00010341)

Abraboro HSS cylindrical drill bits with a 3.4 mm diameter, supplied as a pack of 10, are designed for drilling precise holes in ferrous and non-ferrous metals. Manufactured from high-speed steel (HSS), these drill bits are suitable for both hand-held and stationary drills. They are intended for tasks that require wear resistance and dimensional accuracy, such as work on sheet metal, profiles and mechanical parts.

Advantages

The HSS construction provides a balance of hardness and toughness for reliable cutting performance in a variety of metals. The cylindrical shank ensures stable clamping in drill chucks, while the consistent 3.4 mm diameter supports accurate, repeatable hole sizes. Supplied as a pack of 10, the set allows for multiple operations without frequent reordering and is convenient for workshop and maintenance environments.

Suitable for

• Drilling holes in sheet metal and thin steel plates
• Creating precise bores in aluminium profiles and non-ferrous metals
• Mechanical assembly and maintenance tasks where dimensional accuracy is required
• Use with hand-held drills and drill presses for general metalworking

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 3.4 mm
• Shank type: cylindrical
• Pack quantity: 10 pieces
• Intended materials: ferrous and non-ferrous metals

How to use

Select the appropriate drill speed and feed for the material being drilled; lower speeds and light feed are recommended for harder steels, while higher speeds can be used for aluminium and softer alloys. Secure the workpiece firmly and clamp the drill bit in the chuck so the cylindrical shank is held straight. Apply steady pressure and allow the HSS cutting edges to remove material; withdraw occasionally to clear chips and reduce heat buildup. Use cutting fluid or lubricant where appropriate to extend tool life and improve hole quality.

Usage recommendations

For best results, match drilling speed to the workpiece material, keep the bit well-lubricated during prolonged use, and replace bits when wear affects hole accuracy or increases cutting forces.
