CS-K21r

CS-K21r is a single edge blade for professional digital cutting environments. A 6mm diameter cylindrical shank providing high rigidity for oscillate cutting of denser materials. Cutting of intricate detail and small radii with low overcut. Same cutting parameters as the CS-K21. It is made for shops running Gerber, Kongsberg and Summa cutting systems, making it a practical replacement choice when you need predictable fit and familiar cutting behavior across established digital cutting workflows.

The blade is designed for knife – oscillate work and supports material thicknesses up to 20.75 mm with a 63 degrees + 84 degrees cut angle and a 6o mm blade thickness. The round stock profile gives the blade a familiar handling style for operators who already work with comparable tools.

In day-to-day production, CS-K21r is especially relevant for board – soft such as Corrugated Plastic, Foam Board, Fome-Cor(R), Insite(R) Foam Board and Reboard(R), flexible material such as Carpet, Cork, Ejection Rubber, Foam and Insulation, textile such as Felt, corrugated single such as A Flute, B Flute, C Flute, D Flute and E Flute and corrugated double wall such as A/B Flute, B/C Flute, B/E Flute, E/B Flute and E/C Flute. These material matches make it useful for operators who need one blade option that can be selected confidently for common production boards, films, textiles, composites, packaging stock or flexible sheet materials shown in the product data.

The listed overcut values include a 0 mm start overcut and a 1.6 + 0.11 mm end overcut, which helps operators compare this blade against nearby alternatives when fine tuning corners, lead-ins and small details.

CS-K21r is also listed with compatible or alternative reference terms including 42441642, 6303, 9039, BLD-SR6303, G42441642, Kongsberg BLD-SR6303 (42441642), Oscillate, round stock, S21R, SE21R and SR6303. These references are helpful when replacing an existing blade, comparing supplier part numbers, or confirming that the product matches the naming used in older job sheets and machine setups.
