Expert Tip: Always keep the bit wet. Use a steady stream of water or a spray bottle to cool the bit during the cut. This prevents heat buildup and significantly extends the tool's lifespan. Cut a template guide from scrap wood or follow the freehand method below.

The Angle Start: Do not start drilling flat. Hold the drill at a 45-degree angle to create a small "C" shaped notch or pocket.

1. Leveling Up: Once the notch is established, slowly bring the drill up to a 90-degree perpendicular position.
2. Pressure: Apply light, steady pressure. Let the vacuum-brazed diamonds do the cutting; do not force the bit.

Bathroom & Kitchen Reno: Perfect for installing shower door hardware, towel bars, robe hooks, and soap dispensers on tiled walls.

Plumbing Work: Ideal for creating precision penetrations for faucet lines and small plumbing pipes through quartz backsplashes.

Specialty Projects: Essential for DIY glass aquarium modifications or adding drainage holes to large ceramic planters.

A: Yes! The vacuum brazed diamond coating is specifically designed for hard porcelain, providing a much cleaner cut than standard electroplated bits.
