Drill bit for metal Abraboro HSS cylindrical 9 mm, 10 pcs (AB00010901)

Abraboro HSS cylindrical drill bits for metal, diameter 9 mm, set of 10 pieces are designed for drilling precise, repeatable holes in ferrous and non-ferrous metals. Constructed from high-speed steel (HSS), these drills combine hardness and toughness appropriate for general metalworking tasks. The cylindrical shank fits standard chucks and many drill presses, enabling stable clamping and consistent concentricity when producing 9 mm holes in sheet, plate or machined components.

Advantages

These 9 mm HSS drill bits offer a balance of wear resistance and edge retention suitable for a variety of metalworking applications. The cylindrical shank simplifies mounting in standard handheld drills and bench drills without the need for special adapters. Supplied as a set of 10, the pack supports repeated use and quick replacement in workshop, repair or production environments. The geometry and material selection reduce the risk of premature dulling when used at recommended speeds and with appropriate cutting fluid.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminum and non-ferrous alloys
• Workshop repairs and maintenance tasks
• Prototype and light production runs requiring consistent 9 mm holes
• Use in handheld drills and drill presses with standard chucks

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 9 mm
• Shank type: Cylindrical shank for standard chucks
• Quantity: 10 pieces per set
• Intended use: Drilling metal (ferrous and non-ferrous)

How to use

Secure the drill bit in a properly tightened chuck and ensure the workpiece is clamped to prevent movement. Select a drill speed appropriate to the metal being drilled (lower speeds for harder materials) and apply steady, even feed pressure. Use cutting lubricant or coolant when drilling steels to extend tool life and improve hole finish. Withdraw the bit periodically to clear chips when drilling deeper holes.

Usage recommendations

For best results, match drilling speed to material hardness and use an appropriate cutting fluid. Replace worn bits from the 10-piece set as needed to maintain hole accuracy and surface quality. Always wear suitable eye and hand protection and follow safety guidelines for machine use.
