Step-by-Step Guide to a Flawless Cut

 

  1. Preparation is Key: Mark the exact center of your desired hole on the countertop. Ensure the surface is clean and level.

  2. Secure the Guide: Place the guide with the integrated water cup on your countertop, aligning the center with your mark. You can hold it firmly in place or use clamps for added stability.

  3. Add Water: Fill the water cup with water. The guide is designed to hold the water around the drill bit, providing continuous lubrication.

  4. Begin Drilling: Insert the diamond hole saw into your standard drill and position it inside the guide. Begin drilling at a slow speed, applying gentle, steady pressure.

  5. Let the Kit Do the Work: As you drill, the guide will keep the saw secure and the water cup will keep the cutting edge cool. Let the diamonds do the grinding—there’s no need to apply excessive force.

  6. Drill Through: Continue until you break through the countertop. The result will be a perfectly smooth, clean-edged hole, ready for your new faucet, soap dispenser, or other installation.
