Why Tile Pros Use the Sigma 17D3

Large format and plank tiles are standard on many jobs now, and the stock measurement range on a compact cutter can feel limiting. The Sigma 17D3 Calibrated Extension lets you keep using your trusted 2A3 or 2B3 while gaining extra reach for wider rips and repeat cuts. Instead of eyeballing or juggling a tape, you set the calibrated bar, lock it in, and make consistent cuts run after run.

Because it’s built specifically for Sigma’s Series 2 cutters, the extension sits square, tracks true with the fence, and keeps your measurements aligned with the cutter’s scoring wheel. For installers who rely on Sigma for clean, accurate scoring on porcelain and ceramic, the 17D3 is a practical upgrade that pays off quickly on jobs with repetitive cuts.
