Fein Hook Blade Steel 1 Inch PK2

The Fein 63903207012 hook blade is made from steel for cutting urethane in automotive tasks and caulking in commercial or residential work. It is supplied as a pack of two blades for use with compatible oscillating or rotary tools.

Compatibility With FSC 1.6 FSC 1.6Q AFSC 18

The single specification that decides fit is the tool interface. These blades are designed for use with manufacturer numbers FSC 1.6, FSC 1.6Q and AFSC 18, so they will not fit oscillating tools that use a different mounting system.

Build Integration Two Blades Ready For Urethane

The pack provides two blades so one can be kept as a spare while the other is in use. No additional adapters are mentioned, so the blades mount directly onto the listed Fein multi-tools, freeing the operator from sourcing separate cutting accessories for these materials.
