Geetech
Explore our expertly engineered collection of Geetech woodworking tools, featuring precision spiral cutterheads designed to transform your planing and jointing experience. Whether you're working with a 6-inch jointer or a 20-inch planer, Sheartak's custom-designed cutter heads eliminate common woodworking challenges like tear-out, washboard marks, and excessive noise.
Our spiral cutterhead technology represents a significant advancement in woodworking efficiency. Each mechanical component is precision-crafted with premium carbide inserts arranged in a helical pattern, delivering a superior shear cut that leaves a glassy-smooth finish on even the most challenging figured hardwoods and softwoods. The staggered cutting action ensures your woodworking tools operate significantly quieter while producing exceptional results.
Woodworkers worldwide are retrofitting their Geetech machines with Sheartak spiral cutterheads to experience transformative benefits. The carbide inserts stay sharp up to 50 times longer than traditional high-speed steel blades, with each insert featuring four usable cutting edges. This innovative cutter head design means no more time-consuming blade sharpening—simply rotate to a fresh edge in minutes.
Available for Geetech CT-15, CT-200, CT-204L, CT-344, CT-345, CT-508G, G6, G8, G20 models and more, each spiral cutterhead jointer and planer upgrade includes premium Japan-made NSK bearings, spare carbide inserts, installation hardware, and comprehensive warranty coverage. The precision-ground inserts maintain a tolerance of +/-0.0004" for perfect interchangeability and consistent performance.
Transform your workshop with professional-grade woodworking tools that deliver smoother finishes, dramatically reduced noise levels, easier dust extraction, and maintenance-free operation. Each spiral cutter head is dynamically balanced and ready to install, bringing commercial-quality results to your Geetech equipment. Proudly family-operated, Sheartak offers free consultations to help you select the perfect upgrade for your specific machine model.
