Montolit MiniFlexitile – Precision Cutting and Finishing

Every tile job has the cuts nobody wants: the notch around a supply line, the outlet cut on a backsplash, the edge cleanup tight against a cabinet. A 4-1/2" grinder is too much tool for that work, and dragging a cord around the room doesn't help. The Montolit MiniFlexitile is a compact 12V cordless mini grinder made for exactly those cuts, so you can work right where the tile is.

It spins up to 19,000 rpm and runs Montolit's 50 mm and 76 mm diamond accessories. That covers cutting, shaping, smoothing and rough grinding in one small tool. A 20 mm mandrel comes with it and extends the mounting point so 50 mm accessories seat correctly. Pair it with Montolit MiniFleximont Diamond Flap Discs (50mm) for detail shaping and finishing on porcelain edges.

The guards match the job. Use the metal guard with MINI and MIDI FLEXIMONT for smoothing and rough grinding, and the polymer guard for standard cutting. The included transparent double guard connects to dust extraction and adds protection when you're running 50 mm discs. Every guard reverses for right- or left-handed use.

Why Tile Pros Choose It

• Gets into tight spots: Small enough for notches, outlets, inside corners and edge work that a full-size grinder can't reach cleanly.
• Cordless 12V power: No cord to drag across fresh tile or snag on the ladder.
• 19,000 rpm: Enough speed to cut and shape dense porcelain with Montolit diamond accessories.
• Two accessory sizes: Runs 50 mm and 76 mm Montolit diamond accessories, and the 20 mm mandrel is included.
• USB-C charging: Top it off from a standard USB-C power source (5 V / 3 A) in about 2.5 hours.
• Built-in protection: The automatic brake stops the accessory after use, and the overheat sensor shuts the tool down until it cools.
• Light in the hand: At 1.4 lb, your wrist gives out long after the tile does.
• Battery indicator: Shows remaining charge so you don't run out halfway through a cut.

Pro tip: Mark a notch on both the face and the back of the tile, then plunge from the back first. You'll finish the face cut with a cleaner edge and less chipping on the glaze.
