Bosch Expert 2 608 902 356 spiralbor 1 stk.

The Bosch Expert 2 608 902 356 8 mm diameter twist drill bit is a single-piece high-precision drilling tool designed for general-purpose use. Engineered for clean, accurate holes, this 8 mm bit delivers consistent performance in a range of common materials. The compact design and robust construction make it suitable for both professional tradespeople and DIY enthusiasts who need reliable, repeatable drilling results.

Advantages

This 8 mm twist drill bit offers precise centring and stable cutting action for accurate hole geometry. Its hardened cutting edges retain sharpness for extended use and contribute to efficient material removal. The single-piece design reduces the risk of breakage at joints and provides straightforward handling in standard chucks. Compatibility with standard drill holders and the bit's balanced construction help to minimise vibration and improve user control.

Suitable for

• Drilling holes in wood for fittings and joinery
• Creating holes in plastics and composite panels
• Light to medium metal drilling where an 8 mm diameter is required
• General repair, installation and DIY projects

Key specifications

• Type: Twist (spiral) drill bit
• Diameter: 8 mm
• Material compatibility: wood, plastics, light to medium metals
• Design: single-piece construction for increased durability
• Intended use: general-purpose drilling in handheld or bench drills

How to use

Select an appropriate drill speed for the material: lower speeds for metals and higher speeds for wood and plastics. Secure the workpiece and fit the 8 mm twist drill bit into a compatible drill chuck. Apply steady pressure and allow the bit to cut without forcing; withdraw periodically to clear chips when drilling deeper holes. Use cutting lubricant when drilling metals to reduce heat and prolong bit life. After use, clean the flutes of debris and store the bit in a dry place to prevent corrosion.

Recommendations

For best results, match drill speed and feed rate to the material being drilled, use appropriate clamping and safety equipment, and consider pre-drilling pilot holes for precise positioning. Regular inspection of the cutting edges will help determine when re-sharpening or replacement is necessary to maintain hole quality.
