Alpha® PT Cutter — Porcelain Paver Tile Turbo BladeAlpha® 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") .dst-accordion { margin-top: 25px; border: 1px solid #FDDCC5; border-radius: 6px; overflow: hidden; } .dst-accordion-item { border-bottom: 1px solid #FDDCC5; } .dst-accordion-item:last-child { border-bottom: none; } .dst-accordion-toggle { display: none; } .dst-accordion-label { display: flex; justify-content: space-between; align-items: center; padding: 14px 20px; cursor: pointer; font-size: 17px; font-weight: 700; color: #231F20; background: #fff; transition: background 0.2s; } .dst-accordion-label:hover { background: #FFF3EB; } .dst-accordion-label::after { content: '+'; font-size: 22px; font-weight: 700; color: #F15C22; transition: transform 0.3s; } .dst-accordion-toggle:checked + .dst-accordion-label { background: #FFF3EB; } .dst-accordion-toggle:checked + .dst-accordion-label::after { content: '\2212'; } .dst-accordion-content { max-height: 0; overflow: hidden; transition: max-height 0.4s ease; padding: 0 20px; background: #fff; } .dst-accordion-toggle:checked ~ .dst-accordion-content { max-height: 5000px; padding: 15px 20px 20px; } Models / Part Numbers 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 LT14A+ 14" 2.8 mm 5,360 1", 7/8", 20 mm Gas Demolition / Electric Cut-Off Saws 749173472855 How to Use 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.

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.
