Drill bit Bosch 2.5 mm HSS 2608900132 — high-speed steel twist bit for metal

Bosch 2.5 mm HSS drill bit is a high-speed steel twist bit engineered for drilling metal and other hard materials. With a 2.5 mm diameter and a conventional spiral flute, this bit is intended to produce accurate, clean holes in thin sheet metal, plates and components used in mechanical, maintenance and workshop applications. The HSS material provides improved edge retention and resistance to heat compared with carbon-steel bits, supporting repetitive drilling operations and consistent hole quality.

Advantages

The high-speed steel construction ensures durability and thermal stability during continuous use. The twist flute geometry enables efficient chip evacuation and stable drilling, minimizing burring and reducing the need for secondary finishing. Its 2.5 mm diameter delivers precise hole sizing for mechanical assemblies and fastener preparation. The bit is compatible with common handheld drills and drill presses, offering straightforward installation in standard chucks and reliable concentricity for accurate results.

Suitable for

• Drilling holes in thin and medium-thickness metal sheets (steel, stainless steel, aluminum)
• Preparation of pilot holes for screws and rivets in metal components
• Workshop maintenance, machinery repair and fabrication tasks
• Use with handheld drills and drill presses for production or repair work

Key specifications

• Material: high-speed steel (HSS) designed for metalworking
• Diameter: 2.5 mm for precise hole sizing
• Type: twist drill with spiral flutes for chip removal
• Typical application: drilling metal and other hard materials
• Compatibility: standard drill chucks on handheld drills and drill presses

How to use

Secure the workpiece and use appropriate clamping to prevent movement. Select the Bosch 2.5 mm HSS drill bit and mount it in a properly tightened chuck. For metal drilling, use a suitable cutting fluid or lubricant to reduce heat and prolong tool life. Start at low to moderate speed appropriate for material thickness, apply steady feed pressure, and allow the bit to cut without excessive force. Withdraw the bit periodically to clear chips when drilling deeper holes. After use, clean chips from the flutes and store the bit dry to avoid corrosion.

Usage recommendations

For best results when drilling metal, use cutting fluid and moderate spindle speeds; use a center punch to mark the start point and clamp the work securely to ensure accuracy and safety.
