Spiral cutting drill bit Bosch 2 608 576 181

The Bosch 2 608 576 181 spiral cutting drill bit is an 8 mm precision tool designed for clean, accurate drilling. Engineered for consistent chip removal and smooth hole walls, this drill bit suits a range of common materials encountered in general construction and workshop tasks. Its spiral cutting geometry supports stable drilling with reduced walking and improved guidance at the start of the hole.

Advantages

This 8 mm spiral cutting drill bit delivers precise hole diameters and minimal burr formation thanks to its cutting profile. The bit’s durable material and heat-resistant treatment increase wear resistance and service life under typical drilling loads. Its spiral flute design promotes efficient chip evacuation, reducing clogging and allowing higher feed rates without sacrificing finish quality.

Suitable for

• Drilling precise 8 mm holes in wood and engineered wood products
• Creating pilot holes in light metals and non-ferrous alloys
• General workshop and construction tasks requiring clean, accurate holes
• Use with handheld drills and drill presses for repetitive drilling

Key specifications

• Diameter: 8 mm
• Tip geometry: spiral cutting flute for chip evacuation
• Intended use: precision drilling
• Material treatment: wear-resistant coating/heat treatment for extended life
• Compatible with: standard drill chucks for common electric and cordless drills

How to use

Secure the drill bit in the chuck and tighten according to the drill manufacturer's instructions. Select an appropriate rotational speed for the material being drilled — lower speeds for metals and higher speeds for wood — and apply steady, even pressure without forcing the bit. For deeper holes, withdraw the bit periodically to clear chips and maintain cooling. Use appropriate personal protective equipment and clamp workpieces to prevent movement during drilling.

Usage recommendations

To maximize service life and maintain hole quality, match rotational speed and feed rate to the material, avoid excessive side loads, and keep the bit clean of accumulated debris. For repeated precision holes, use a drill press or guide to maintain alignment and consistent depth.
