Drill bit Abraboro HSS cylindrical for metal 10.5 mm, 5 pcs (AB00011050)

Abraboro HSS cylindrical drill bits for metal, diameter 10.5 mm, set of 5 pieces. Manufactured from high-speed steel (HSS), these drill bits are designed for cutting and drilling in ferrous and non-ferrous metals. The cylindrical shank fits standard chucks and is suitable for workshop and industrial applications including metal fabrication, maintenance and repair tasks.

Advantages

High-speed steel construction provides good wear resistance and heat tolerance for repeated drilling operations in metal. The cylindrical shank ensures secure clamping in standard drill chucks and straightforward bit changes. Supplied as a set of five, the pack offers quick replacement of worn tips or multiple bits for production tasks. Geometry and material are chosen to deliver consistent hole quality in both ferrous and non-ferrous materials when used with appropriate speeds and lubrication.

Suitable for

• Drilling holes in steel and cast iron
• Working with aluminium and non-ferrous alloys
• General workshop maintenance and repair
• Metal fabrication and assembly tasks
• Production environments requiring multiple spare bits

Key specifications

• Material: high-speed steel (HSS)
• Drill diameter: 10.5 mm
• Shank type: cylindrical (straight shank)
• Quantity in set: 5 pieces
• Suitable for: ferrous and non-ferrous metals

How to use

Secure the drill bit in a compatible drill chuck, ensuring the shank is clamped firmly and the bit runs true. Select an appropriate spindle speed and feed rate for the workpiece material — lower speeds for harder steels, higher speeds for aluminium — and apply cutting fluid or lubricant when drilling ferrous metals to reduce heat and extend tool life. Start with a center punch or pilot hole if precise positioning is required, and back the bit out periodically to clear chips and avoid jamming. After use, clean chips and residue from the flutes and store the bits in a dry place.

Usage recommendations

Use recommended cutting speeds, steady feed, and lubrication appropriate to the material being machined. For hardened steels or interrupted cuts, consider pre-drilling with smaller diameters and inspect bits for wear; replace when edges become rounded or chipping appears to maintain hole quality and operator safety.
