Sigma 14A Scoring Wheel — A Fresh Edge for Clean Pulls A worn scoring wheel is the most common reason a good cutter starts giving bad breaks — the score goes shallow and ragged, and the snap follows it. The Sigma 14A puts a precision-ground tungsten-carbide edge back on your pull-style cutter, so you're back to uniform score lines, reliable snapping, and reduced edge chipping. It's a 12 mm tungsten-carbide wheel for Sigma pull-style manual cutters, including the 2-series and Technica models. Precision-ground for durability and a clean cut, it's the simplest, cheapest upgrade you can make to a cutter that's started to struggle. Fits cutters like the Sigma 2G and other pull-style machines. Why Tile Pros Choose It Clean, uniform scores: Precision-ground tungsten carbide for reliable snapping Less chipping: A sharp wheel protects the cut edge Right fit: 12 mm wheel for Sigma pull-style cutters (2-series, Technica) Durable: Tungsten carbide holds its edge through heavy use Cheap fix, big difference: The most overlooked cause of bad breaks Pro tip: Don't wait for total failure — if you're pressing harder or scoring twice, the wheel is done. Make sure the carriage and holder are clean when you install the new wheel so it tracks a single straight line.
