Blades and cutting sets for the cordless insulation saw, in 240 and 350 mm. The letter in the code is the material: one pattern for soft mineral and natural fibre, another for rigid board. The wrong one either tears the batt or packs solid within a metre. Cutting sets supply a matched pair, since these saws run two blades against each other. The angle stop keeps the cut square — which decides whether the next piece sits tight or leaves a thermal bridge.
