How to use

Select the appropriate hole saw diameter for the intended pipe or conduit size and secure it to the adapter along with the pilot drill. Insert the assembly into a compatible drill chuck and tighten firmly. Position the pilot drill against the marked center point of the material and begin drilling at a moderate speed, maintaining steady and even pressure. Avoid excessive force to prevent overheating and ensure a clean cut, clearing away debris from the teeth periodically during extended cutting operations.

What to consider before purchase

• Verify that your power drill is compatible with the included adapter and pilot drill shank
• Check the required hole diameters for your specific plumbing or installation project
• Confirm that the target materials fall within the recommended metal, wood, and plastic categories

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and gloves, when operating power tools and cutting metal or plastic. Use cutting fluid when drilling through metal to extend the lifespan of the bi-metal teeth and prevent overheating.
