Drill bit Bosch 8 mm diameter 2608615028 for metal and wood

Bosch drill bit 8 mm diameter 2608615028 is a straight-shank twist drill designed for drilling through metal and wood. The bit produces accurate 8 mm holes and fits standard drill chucks, offering consistent drilling performance for assembly, repair and construction tasks. Its geometry and cutting edges are optimized to provide stable drilling progress and reliable centring when starting holes in a variety of common materials.

Advantages

The drill bit combines a sturdy construction with sharp cutting edges to maintain hole accuracy and resist wear during repeated use. Compatibility with standard chucks makes it suitable for most hand-held and bench drills. The bit’s balanced design helps minimise wobble and reduces the need for secondary finishing, while heat resistance in the cutting zone improves lifespan when drilling in metal.

Suitable for

• Creating 8 mm holes in mild steel, sheet metal and cast parts
• Drilling through soft and hardwoods for assembly and joinery
• General repair, maintenance and construction site tasks
• Workshop projects and DIY home improvements

Key specifications

• Diameter: 8 mm
• Shank type: straight round shank for standard chucks
• Intended materials: metal and wood
• Drill type: twist drill with ground cutting edges
• Typical use: through-holes and clearance holes

How to use

Secure the drill bit in the chuck and tighten firmly before operation. Select an appropriate drilling speed: lower RPM for metal and higher RPM for wood, following the drill and material manufacturer’s recommendations. Use cutting lubricant or coolant when drilling metal to reduce heat and prolong bit life. Start drilling with steady, moderate pressure, withdraw occasionally to clear chips when drilling deep holes, and finish by easing pressure as the bit breaks through the material to maintain hole quality.

Usage recommendations

Wear suitable personal protective equipment including eye protection and gloves. For precise positioning, centre-punch metal surfaces before drilling. Replace the bit when cutting edges become dull or when increased runout is observed to avoid poor hole quality and potential workpiece damage.
