WkretMet - WK-FT - Nylon cutter for polystyrene
What is Wkręt‑met WK‑FT?
The Wkręt‑met WK‑FT is a professional plastic cutter designed for creating recessed holes in polystyrene insulation, enabling the installation of fasteners in a concealed, thermally efficient way. It is used together with polystyrene discs (KS/KSG) to minimise thermal bridging and prepare the façade for a smooth, flush finish.
The tool features a thrust collar that ensures a controlled cutting depth of 20mm, allowing installers to recess fixings safely and consistently. This significantly reduces point thermal conductivity and speeds up façade finishing work.
Key Features
Controlled cutting depth – built‑in thrust collar ensures precise 20mm recessing
Designed for concealed installation – ideal for immersed mounting of façade fixings
Reduces thermal bridging – enables use of polystyrene discs to minimise point heat loss
Fast and clean cutting – optimised for EPS and graphite polystyrene boards
Compatible with Wkręt‑met KS/KSG discs – perfect fit for 66.7mm polystyrene plugs
Improves façade finish quality – creates a flush surface ready for basecoat and mesh
Durable plastic construction – lightweight, impact‑resistant, and long‑lasting

Application Checklist
Mark fixing points on the insulation board.
Use WK‑FT to cut a 20mm recess into the polystyrene — the thrust collar ensures correct depth.
Install the façade fastener (e.g., WKTHERM S‑8) into the recessed hole.
Insert a KS/KSG polystyrene disc to cover the fixing head and eliminate thermal bridging.
Apply basecoat and mesh over the prepared surface for a smooth, even façade.
Where to Use Wkręt‑met WK‑FT
External Thermal Insulation Composite Systems (ETICS)
EPS and graphite EPS insulation boards
Recessed installation of façade fixings
Thermal bridge reduction in EWI systems
Preparation for high‑quality façade finishing
Why Installers Choose WK‑FT
The WK‑FT is a must‑have tool for professional EWI installers who want:
cleaner façade finishes
reduced thermal bridging
faster installation
consistent recess depth
compatibility with Wkręt‑met fixing systems
It’s a small tool that makes a big difference in the quality and performance of an insulation system.
