Alpha® PT Cutter — Porcelain Paver Tile Turbo Blade
Alpha® engineered the PT Cutter specifically for porcelain paver tile, delivering clean, minimal-chip cuts in the most demanding hardscape applications. A sintered turbo-rim diamond layer bonded directly to the steel core enables fast dry cutting and curved step cuts on angle grinders, gas-powered demolition saws, and electric cut-off saws.
Features
- Purpose-built for porcelain paver tile and demanding hardscape work
- Sintered turbo-rim diamond layer bonded directly to a tough steel core
- 8 mm tall diamond layer for extended blade life
- Cuts wet or dry — ideal where water is impractical
- 9" model fits angle grinders; 12" and 14" fit gas-powered demolition saws and electric cut-off saws
- Curved cutting via step-cutting technique
- Includes arbor adapters (20 mm and 7/8" on 12" and 14")
| Part No. | Diameter | Thickness | Max RPM | Arbor(s) | Saw Type | UPC |
|---|---|---|---|---|---|---|
| LT09A+ | 9" | 2.5 mm | 6,600 | 7/8", 5/8", Quad-W5 | Angle Grinders | 749173472978 |
| LT12A+ | 12" | 2.6 mm | 6,200 | 1", 7/8", 20 mm | Gas Demolition / Electric Cut-Off Saws | 749173472862 |

- Match the blade size and arbor to your saw — 9" (LT09A+) for angle grinders, 12" (LT12A+) or 14" (LT14A+) for gas demolition or electric cut-off saws.
- Mount the blade with the correct flange and arbor adapter; verify the arrow on the blade matches the saw rotation.
- Score the porcelain paver tile lightly along the cut line first — this guides the blade and prevents overheating and edge break-out.
- Run the saw at 3/4 of maximum spindle speed; let the blade do the work without forcing it into the tile.
- For curves and box cut-outs use step cutting — multiple shallow passes that nibble the curve.
- If the blade starts to wobble from heat, lift it out and free-spin it in air for several seconds to cool.
- Wet cutting always extends blade life; use water whenever the saw and jobsite allow.

Is a 16" diameter PT Cutter available?
No. Only 9", 12", and 14" diameters are manufactured. The 12" and 14" ship with 20 mm and 7/8" arbor adapters.
Why should I score the porcelain paver before cutting?
Scoring creates a guide path that keeps the blade tracking straight and prevents overheating and breakage of the tile.
Why does the blade become wobbly during a cut?
The softer steel body absorbs cutting impact, so it can wobble when overheated. Run the saw at 3/4 max spindle speed and free-spin the blade in air to cool whenever wobble appears.
Can the PT Cutter be used on other paver tiles?
Yes, but Alpha® recommends staying within porcelain paver applications — that is where the blade truly excels.
Does the PT Cutter work on walk-behind floor cutters?
No. The blade does not include the pin hole required by walk-behind floor cutters.
How do I cut internal corners and box cut-outs?
Use the Alpha® Katana on an angle grinder or stone cutter for small straight cuts, and the Alpha® Contour blade for curves and openings.
Can the 12" PT Cutter run on a 14" saw?
Yes, provided you keep the saw at 3/4 of maximum speed and free-spin the blade between cuts to cool it.
Is the PT Cutter compatible with electric cut-off saws?
Yes — the 12" model is rated for electric cut-off saws.
