Drill bit Bosch 8 mm diameter 2608833811 for metal and wood drilling

Bosch drill bit 8 mm diameter 2608833811 is a straight-shank twist bit designed for drilling precise 8 mm holes in common materials such as metal and wood. Compatible with standard power drills, this bit is intended for general-purpose fastening and assembly tasks where a consistent hole diameter and straight drilling are required. The bit’s geometry provides reliable chip removal and stable cutting action for routine workshop and on-site applications.

Advantages

The drill bit offers a consistent 8 mm hole size with accurate centering for repeatable results. Its twist-flute design supports efficient chip evacuation and reduces binding during drilling in both metal and wood. The straight shank fits most standard drill chucks for quick installation and secure grip. The material and heat treatment provide sufficient hardness for everyday DIY and professional use, delivering predictable performance across a range of common drilling tasks.

Suitable for

• Drilling 8 mm holes in mild steel and sheet metal
• Creating 8 mm holes in soft and hardwoods for dowels or fasteners
• General fastening and assembly work in workshops and construction sites
• Routine maintenance and DIY projects requiring a precise 8 mm hole

Key specifications

• Diameter: 8 mm
• Type: twist drill bit with straight shank
• Compatible tool: standard power drills with matching chuck
• Materials for use: metal (including mild steel) and wood
• Cutting geometry: two-flute twist for chip evacuation

How to use

Select a drill with a chuck that securely grips an 8 mm straight shank. Mark the drilling position on the workpiece and, for metal, use a center punch to prevent wandering. Set the drill at the appropriate speed: lower speeds for metal, moderate to higher speeds for wood, and apply steady, moderate pressure. Start drilling perpendicular to the surface, keeping the bit aligned to maintain a straight hole. Withdraw the bit periodically when drilling deeper holes to clear chips and reduce heat buildup. After drilling, remove burrs or sharp edges from the hole as needed.

Usage recommendations

Use cutting fluid or lubricant when drilling metal to extend bit life and improve cutting performance. Secure the workpiece with clamps or a vise before drilling to ensure safety and accuracy. Inspect the bit for wear or damage and replace when the tip becomes dull or chipped to maintain clean, precise holes.
