Grizzly

Welcome to Sheartak’s Grizzly woodworking tools collection, focused on high-performance spiral cutterhead upgrades designed especially for Grizzly machines. These precision mechanical components bring professional-level cutting quality, durability, and efficiency to your workshop.

Each cutter head in this range uses multiple rows of indexable carbide inserts arranged in a spiral pattern, delivering a shear-cutting action that reduces tear-out and produces a consistently smooth surface. This makes them an ideal choice among woodworking tools for both planers and jointers.

The spiral design not only improves finish, but also helps minimize noise: because only a few inserts make contact at a time, your machine runs more quietly and with less vibration. And thanks to the indexable inserts, you can rotate to a fresh cutting edge when one side dulls — meaning lower maintenance costs.

Furthermore, the helical arrangement generates fine wood chips that are easily evacuated by dust-collection systems, helping keep your workspace clean. For those using a spiral cutterhead jointer, this collection offers a robust, high-efficiency upgrade that extends tool life and boosts performance.
