Equipment and spare partsBrowse manufacturers Search by manufacturerFounded in 1923 in Switzerland, OERTLI Werkzeuge AG is a globally recognized pioneer in high-precision cutting tools for industrial wood processing, timber window manufacturing, and CNC joinery. We supply genuine OERTLI CAT knife systems, SINUS cutterheads, HPC+ window tooling, and HYDRO-GRIP clamping chucks worldwide.
The patented Swiss OERTLI CAT knife clamping system guarantees micron-precise, clearance-free seat positioning of indexable turnover knives without manual adjustment. Carbide inserts are clamped into high-accuracy wedge pockets with positive mechanical stops, ensuring identical cutting diameters across insert replacements. The modular CAT-Flex concept enables mounting multiple different profile knives into one standardized cutterhead body.
OERTLI SINUS planer heads feature a wave-like spiral arrangement of micrograin tungsten carbide (HW) and high-speed steel (HSST) knives. The uninterrupted peeling cut eliminates shock impacts, reduces acoustic emissions by 10–15 dB, and delivers flawless planer surfaces without ripples even on cross-grained timber. Cutter bodies are fully engineered for high feed velocities on four-sided moulders.
OERTLI HPC (High Performance Cutting) and HPC+ tooling systems are engineered for industrial manufacturing of modern timber and wood-aluminum window frames on angle processing centers and CNC machinery. They perform tenoning, slotting, glazing bead rebating, and outer contouring in minimum cycles, combining extreme stock removal rates with zero tear-out on visible surfaces.
OERTLI CNC shank tooling solutions for 3-, 4- and 5-axis machining centers comprise solid tungsten carbide (VHM) spiral end mills, polycrystalline diamond (DP/PCD) cutters, and indexable turnover knife shanks with integral HSK-F63 and HSK-E63 taper clamping. High-precision balancing ensures completely smooth operation at spindle speeds up to 24,000 RPM without harmonic vibration.
TURBEX 3rd generation modular tooling systems are multi-stage stacked cutterhead assemblies designed for comprehensive profiling of sashes, frames, and mullions. The system guarantees exact seal groove dimensions and hardware rebates in minimum cutting cycles. Lightweight alloy cutter bodies minimize rotational inertia on machine spindles during frequent start-stop sequences.
Cutterheads in the CASTOR, CASTOR-Finish, CASTOR-Classic and CASTOR SPRINT series are designed for high-feed calibration and planing of glulam, solid timber and furniture panels. The centrifugal self-locking mechanism of CASTOR SPRINT minimizes knife replacement time to seconds, guaranteeing dependable insert seating and equalized chip loading under heavy machining cuts.
The OERTLI circular saw blade portfolio comprises over 1,600 specialized configurations for rip sawing, cross-cutting solid hardwood/softwood, laminated panels (MDF, HDF, particleboard, plywood), as well as aluminum and composite extrusions. Thermally tensioned saw plates featuring laser expansion slots prevent lateral wobble during intensive continuous production.
OERTLI HYDRO-GRIP hydraulic chucks and sleeves (Types A, B, C, D, G, GPW-25, GS-25) deliver concentric, zero-backlash clamping for cutterheads on machine spindles. The internal hydraulic pressure chamber generates uniform radial pressure along the entire seating bore, eliminating micro-eccentricity and extending knife service life by 50% to 100%.
Based on unique customer drawings and architectural specifications, OERTLI engineers custom-tailored multi-profile cutter combinations for specialized timber facades, historic window renovations, structural glulam components, and complex furniture elements, providing kinematic cutting analysis and CAD/CAM collision verification.
All supplied OERTLI Werkzeuge AG tooling products are manufactured at Swiss and German facilities adhering strictly to European industrial safety regulations. Every tool undergoes dynamic spin balancing and permanent laser marking of operational limits, guaranteeing absolute reliability in heavy-duty manufacturing environments.
Our tooling engineers calculate cutting geometry and kinematic force distributions based on window, door, and joinery architectural blueprints. We design multi-stage cutterhead segmentations, selecting optimal shear angles and sub-micron carbide grades tailored precisely to your timber species (pine, oak, larch, beech, accoya) to ensure chip-free, ultra-smooth surfaces.
We engineer and deliver turnkey OERTLI tooling configurations for high-capacity automated window processing centers and CNC machines from leading global builders: Weinig (Conturex, Unicontrol), Biesse (Rover), Homag (Centateq), SCM (Accord, Windor), and IMA.
All OERTLI cutter bodies and knife seats are machined in Switzerland and Germany to stringent radial and axial runout tolerances. Every assembled tool undergoes 100% dynamic balancing to ISO 1940 Grade G2.5 and strictly meets the European DIN EN 847-1 safety mandate.
All genuine OERTLI tooling products are supplied directly from European manufacturing facilities in heavy-duty protective cases, accompanied by comprehensive CAD technical drawings, dynamic balance inspection certificates, and quality control reports, supported by reliable international logistics.
