One Tool, Three Sizes
Drill or enlarge crisp, round openings with a single stepped design—20mm (0.79in), 35mm (1.38in), and 50mm (1.97in). Each step features approx. 12mm (0.47in) cutting height for stable guidance and low chip breakout.
Heavy-Duty Diamond Performance
Multi-layer diamond abrasive bites smoothly into tough materials for fast penetration, cool grinding, and extended lifespan—ideal for repeated, professional use.
M10 Universal Mount
Compatible with angle grinders and electric hand drills (drills require an adapter). Quick to install, no special skills needed—perfect for contractors and DIYers alike.
For Hard Surfaces
Designed for ceramic tile, porcelain, slate, marble, granite, quartz, concrete, and more. Achieve smooth edges and accurate holes for faucets, cable pass-throughs, countertops, and renovation tasks.
Imagine This…
Mark your center, engage the first step, and feel the tool glide with a solid, low-vibration touch. Step down as needed to reach 35mm or 50mm—no bit changes, no guesswork, just clean, round holes in minutes.

FAQ
Q1: Does it fit my drill?
A: The bit uses an M10 thread. Angle grinders with M10 mount fit directly. Electric drills need an M10-to-3/8" adapter (select the bundle option).
Q2: Can I drill through porcelain tile and granite?
A: Yes. Use low to moderate speed with light feed pressure. For very hard porcelain or granite, apply water cooling to reduce heat and extend tool life.
Q3: How do I get clean edges?
A: Start perpendicular, let the first step establish the circle, then progress to larger steps. Avoid excessive force; allow the diamond to cut. Taping the surface and using water helps minimize chipping.
Q4: Is this for making new holes or enlarging existing ones?
A: Both. The stepped shape is excellent for enlarging pre-drilled holes and for new holes in stone and tile.
Q5: What if I only need one size?
A: Choose a single-size listing or use the 3-in-1 stepped bit to cover future tasks—often more cost-effective over time.
