Frequently Asked Questions

What materials can Bosch Professional flat drill bits cut through?

Bosch Professional flat bits are specifically designed for wood, chipboard, MDF, plywood, and softwood timber. They're not suitable for metal, masonry, or plastic materials. For best results, use them at appropriate speeds—typically slower for larger diameter bits and hardwoods.

How do I maintain my Bosch Professional flat bits?

Keep bits clean and free from resin build-up by wiping after use. Store in a dry environment to prevent rust. Sharpen cutting edges periodically with a fine file, maintaining the original bevel angles. Avoid excessive heat during drilling which can compromise the hardened edges.

Are Bosch Professional flat bits compatible with impact drivers?

Yes, the hexagonal shank design works perfectly with both standard drill chucks and impact driver quick-release holders. However, for best control and cleaner holes, a standard drill/driver in drilling mode is recommended for most applications.
