Drill bit Bosch 8 mm HSS 2608680278 for metal drilling

Bosch 8 mm HSS drill bit is a high-speed steel twist bit designed specifically for drilling metal. With an 8 mm cutting diameter and HSS material construction, this drill bit provides consistent cutting performance for steel and other ferrous and non‑ferrous metals. It is intended for use with hand-held drills and drill presses in workshop and industrial environments, offering straightforward, reliable metal‑drilling capability for general repair, fabrication, and maintenance tasks.

Advantages

The HSS material ensures good hardness and heat resistance during metal drilling, reducing wear under typical operating conditions. The 8 mm diameter offers a balance between hole size and rigidity for precise holes in sheet metal, plate, and structural components. The twist‑flute geometry helps evacuate chips efficiently, improving cutting stability and extending tool life when used with appropriate speeds and lubrication.

Suitable for

• Drilling holes in mild and stainless steel
• Work on non‑ferrous metals such as aluminium and brass
• General metalwork in workshops and maintenance tasks
• Use with corded or cordless hand drills and drill presses

Key specifications

• Material: High‑speed steel (HSS)
• Diameter: 8 mm
• Flute type: Spiral twist flute for chip removal
• Intended application: Metal drilling (ferrous and non‑ferrous)
• Shank type: Straight cylindrical shank for standard drill chucks

How to use

Secure the drill bit in the drill chuck so it is straight and firmly held. Select a drilling speed appropriate for the metal being drilled—lower speeds for stainless steel and harder alloys, higher speeds for aluminium and softer metals. If drilling thick or hard materials, use cutting fluid or lubricant to reduce heat and improve chip evacuation. Start with a center punch for accurate hole location when necessary, apply steady pressure without forcing the bit, and back out periodically to clear chips and prevent clogging.

Usage recommendations

For best results and extended bit life, match drill speed and feed to the material: use lower RPM and cutting oil on stainless and hardened steels, and higher RPM with less pressure on softer metals. Maintain a sharp cutting edge and replace the bit if excessive wear or chipping occurs. Always follow appropriate safety practices including eye protection and secure workholding.
