T1 HSS 1-1/2″ × 1/4″ Corrugated-Back Knife Bar — 25″

Description

The CB102T6 is a 25-inch T1 tungsten high-speed steel corrugated-back knife bar, 1-1/2 wide and 1/4 thick, for corrugated-back (CB) moulding and planing heads with 60° corrugation. The 60° corrugated back interlocks with the matching corrugations machined into the head body, providing positive mechanical knife retention that prevents the knife from shifting radially during operation — the standard retention system on Schmidt corrugated-back heads and the most widely used knife-locking geometry in moulder and shaper knife-head design. Bar-length stock is cut to the required knife length for the profile and head configuration in-shop, then ground to the finished moulding profile on a surface grinder. The 1/4 thickness must match the head’s knife slot specification; the 1-1/2 width determines the maximum profile height achievable from this bar. T1 HSS is the standard knife material for corrugated-back moulding heads — reliable, consistent edge quality, and resharpened on standard HSS surface grinding equipment. A solid choice for general architectural moulding and furniture profiling in softwood and mixed species. Confirm the head slot accepts 1/4-thick knife stock at 1-1/2 knife height. 60° corrugated back; 25-inch bar length.
