Invicta
Welcome to Sheartak’s Invicta tools collection, where we offer high-quality upgrade options for vintage and industrial Invicta woodworking machinery. This collection features precision mechanical components like spiral cutterhead systems that significantly enhance the performance of Invicta planers and jointers.
Each cutter head employs a helical arrangement of carbide inserts to deliver a smooth, shear-cutting action, minimizing tear-out and producing a refined surface finish. As essential woodworking tools, these heads turn your Invicta machines into high-precision equipment.
The spiral configuration also reduces noise and vibration: because only a few inserts engage at once, your machine runs quieter and more steadily. When a cutting edge dulls, simply rotate the insert to expose a fresh edge — making maintenance efficient and cost-effective.
Additionally, the spiral layout creates fine chips instead of bulky shavings, improving dust-extraction efficiency and keeping your workspace cleaner. For those using a spiral cutterhead jointer or planer in the Invicta lineup, this collection offers a durable, high-value upgrade that enhances both precision and longevity.
