Alpha® Trim Master — Dry Cutting Diamond Blade for Miter SawsThe Alpha® Trim Master is a specialty dry-cutting diamond blade engineered for sliding miter saws — the go-to blade for countertop fabricators cutting backsplashes, end caps, baseboards and molding from granite and engineered stone. An 8 mm tall diamond layer delivers long life, and the blade's consistent feed and finish make it the preferred dry blade for back-splash work. Two sizes are available: the TM10A+ (10", 2.2 mm kerf, 5,900 max RPM, 5/8" arbor) for typical miter saws, and the TM12A+ (12", 2.5 mm kerf, 6,200 max RPM, 1" with 5/8" reducer) for larger sliding miter saws.Features 8 mm tall diamond layer — built for long service life Engineered for dry cutting on sliding miter saws — best-in-class for back-splashes Perfect for granite and engineered stone fabrication Consistent performance, easy operation, clean finish Can also be used as a wet-cutting blade when water is available Available in 10" (TM10A+) and 12" (TM12A+) configurations Standard miter-saw arbors (5/8" for 10"; 1" with 5/8" reducer for 12") .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. Size Thickness Max RPM Arbor UPC TM10A+ 10" 2.2mm 5,900 5/8" 749173461408 TM12A+ 12" 2.5mm 6,200 1", 5/8" 749173461545 How to Use Mount the Trim Master on a sliding miter saw rated for the blade's max RPM (5,900 for TM10A+; 6,200 for TM12A+). Confirm the rotation direction — the arrow is printed on the front and embossed on the back; diamond bond tails should trail the rotation. Lock the workpiece securely and align the cut. Use the sliding method — lower the blade, then slide through the workpiece for the cleanest cut. Run dry for typical back-splash and trim work; water may be added for extra heat control on long cuts. Recommended saws: Bosch 4410L, Bosch 3915, Milwaukee 6497-6, Metabo KGS303 or equivalent sliding miter saw. If cutting speed slows, the diamonds may be glazing — re-dress the blade with a dressing stone or concrete block. Cut granite and engineered stone primarily; marble can be cut but with higher chipping risk — reduce feed pressure. Inspect the blade between cuts and confirm it is true and undamaged.

The bond tails behind the diamonds should point opposite the rotation direction.Which saws are recommended?Higher-RPM sliding miter saws — for example Bosch 4410L, Bosch 3915, Milwaukee 6497-6, Metabo KGS303 or equivalent.What can I cut with the Trim Master?Primarily granite and engineered stone. Marble can be cut but with a higher risk of chipping — reduce feed pressure and use the sliding method.Can I use it as a wet blade?Yes. The Alpha® Trim Master is a dry blade by design, but it can be used with water for heat control on demanding cuts.What is the recommended cutting method?The sliding method — lower the blade, then slide through the work — produces the cleanest cuts on a sliding miter saw.What if the blade slows down or stops cutting cleanly?The diamonds are likely glazing. Re-dress the blade using a soft abrasive — an Alpha dressing stone or a piece of concrete block works well.What are the maximum RPMs and arbor sizes?TM10A+ is 10" with a 2.2 mm kerf, 5,900 max RPM and 5/8" arbor. TM12A+ is 12" with a 2.5 mm kerf, 6,200 max RPM and 1" arbor (5/8" reducer included).
