Drill bit Abraboro HSS cylindrical 5.0 mm set 10 pcs (AB44005000)

Abraboro HSS cylindrical 5.0 mm drill bit set contains ten identical high-speed steel bits designed for drilling metal. Each bit in the set has a 5.0 mm nominal diameter and a cylindrical shank suitable for standard drill chucks. The set is intended for general metalworking tasks such as through-holes, pilot holes, and repair or fabrication work in workshops and maintenance environments.

Advantages

High-speed steel construction provides a balance of hardness and toughness for cutting metal. The cylindrical shank ensures secure clamping in standard chucks and simplifies bit changes. Supplying ten identical bits offers convenience for repetitive tasks and reduces downtime when a bit becomes worn. The uniform diameter makes the set suitable for consistent hole sizes across multiple workpieces.

Suitable for

• Drilling through-holes in steel and other ferrous metals
• Creating pilot holes before tapping or larger drilling operations
• General metal fabrication and repair tasks in workshops
• Maintenance and service work requiring consistent 5.0 mm holes

Key specifications

• Material: high-speed steel (HSS)
• Number of pieces: 10 identical drill bits
• Nominal diameter: 5.0 mm
• Shank type: cylindrical (straight) shank for standard chucks
• Intended application: drilling metal and general workshop use

How to use

Select a drill or drill press with a compatible chuck and secure the cylindrical shank of the 5.0 mm bit firmly in the chuck. Set an appropriate spindle speed for the metal being drilled (lower speeds for harder or thicker materials). Use cutting fluid or lubrication when drilling steel and other ferrous metals to reduce heat and extend bit life. Apply steady, even feed pressure and avoid excessive side loading. After use, inspect the cutting edges for wear and replace the bit from the set when performance declines.

Usage recommendations

For best results when drilling metal, use cutting oil, clamp the workpiece securely, and choose a drill speed appropriate to the material. Replace bits as soon as they show signs of bluntness to maintain hole quality and reduce the risk of workpiece damage.
