This metric drill guide is the perfect helper for accurate drilling with bit sizes ranging from 4 mm to 10 mm.

The guide is designed as a sturdy bar with clearly labeled holes, making it quick and easy to select the right size for your project.

What makes this tool special is the V-shaped groove on the underside, allowing it to:

• sit securely on round pipes,
• rest firmly on corners and edges,
• and lie flat on smooth surfaces.

Whether you're working in the workshop, on-site, or at home, this guide offers a reliable and precise way to drill straight holes without slipping.
