Drill bit Bosch 8 mm HSS model 2608833893 for metal and general drilling

Bosch drill bit 8 mm HSS model 2608833893 is a single high-speed steel cutting tool engineered for drilling metal and general-purpose materials. The 8 mm diameter provides a standard size for pilot holes, clearance holes and through-holes in steel, iron, non-hardened metals and common workshop materials. The HSS material and precision-ground flutes deliver consistent cutting performance and wear resistance suitable for handheld drills and drill presses.

Advantages

The HSS construction ensures good hardness and heat resistance during intermittent and continuous drilling. Precision-ground geometry gives straight, accurate holes with reduced wobble and consistent chip evacuation. The compact 8 mm diameter balances rigidity and cutting speed, making the bit suitable for a wide range of metalworking and general drilling tasks. The bit is compatible with standard drill chucks and can be used with variable-speed drilling equipment.

Suitable for

• Drilling holes in mild steel, iron and non-hardened metal sheets
• Creating pilot or clearance holes for bolts and fasteners
• Workshop repairs and maintenance with hand drills
• Drill press operations requiring an 8 mm hole
• General-purpose drilling in softer construction materials

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 8 mm
• Tip and flute: Precision-ground geometry for accurate drilling
• Suitable for: Metal and general-purpose materials
• Compatibility: Standard drill chucks and drill presses

How to use

Secure the workpiece and choose an appropriate clamp or vice to prevent movement. Install the 8 mm HSS bit into a compatible drill chuck and tighten securely. Select the correct rotational speed for the material — lower speeds for harder metals, moderate speeds for mild steel — and apply steady, even pressure while drilling. Use cutting fluid or lubricant when drilling thicker or tougher metals to reduce heat and improve tool life. Withdraw the bit periodically to clear chips if necessary.

Usage recommendations

For best results when drilling metal, use a suitable cutting lubricant, maintain steady feed speed, and avoid excessive pressure that can cause overheating. Inspect the drill bit regularly and replace it when worn to maintain hole quality and safety.
