This is a drywall grooving system designed for cutting precise 90-degree V-grooves in plasterboard and drywall on a Festool TS 55 or TSC 55 track saw.\u003c\/p\u003e\n\u003cp\u003eA 90-degree V-groove lets a single sheet of board fold into a crisp outside corner, box out a column, or wrap a soffit without a seam on the corner. Cutting that groove by hand is slow and inconsistent. On a track saw running along a rail, the groove is straight, the depth is consistent, and the fold lines up every time.\u003c\/p\u003e\n\u003cp\u003eThe Pro set replaces the saw blade with a machined cutter disc that holds square and triangular inserts. Byrne rates the blade depth at 17mm (about 11\/16 in). When the inserts wear, you rotate them to a fresh edge instead of replacing the whole disc. Replacement inserts are sold as the BE-DT20 set.\u003c\/p\u003e\n\u003cp\u003eThe kit includes an aluminum alloy housing (case cover) that encloses the cutter on the saw, a locker, and the Torx T15, Torx T20, and 5mm hex drivers needed for installation and insert changes. That keeps everything needed to swap from a wood blade to V-grooving in one package.\u003c\/p\u003e\n\u003cp\u003eWho should buy this: drywall finishers, interior fit-out crews, and dry-lining contractors who already run a Festool TS 55 and want clean folded corners without a dedicated machine.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails id=\"product-benefits\"
