Spiral Cutter head for Shopsmith Planer, Pro-Planer with 40 carbide cutters

Spiral Cutter Head for the Shopsmith Planer Pro-Planer Model M5990-B 505990, equipped with 40 carbide cutters.

Shopsmith machine owners are increasingly retrofitting spiral cutter heads onto their older planers and jointers for several compelling reasons:

Smooth Finish with No Tear-out: Each carbide cutter sits at a slight angle, producing a shear cut. The staggered arrangement of the cutters ensures a superior finish compared to traditional straight knives, virtually eliminating tear-out even on highly figured hardwoods.

Reduced Noise: The spiral arrangement allows fewer cutters to engage the wood at any given moment, significantly reducing noise levels during operation.

Extended Tool Life: Featuring sintered tungsten carbide inserts (15x15x2.5mm), the spiral cutter head offers more than ten times the lifespan of traditional high-speed steel knives. Each insert boasts four edges, and changing them is quick and easy.

Ease of Maintenance: The precision-ground carbide inserts are interchangeable and can be rotated 90° to expose a fresh cutting edge. This straightforward process takes only minutes, ensuring minimal downtime.

Improved Dust Extraction: The spiral cutter head generates thinner and shorter wood chips, facilitating more efficient dust collection systems.

Cost Efficiency: By delivering a smoother finish that often eliminates the need for sanding, and by eliminating the costs associated with frequent sharpening, the spiral cutter head proves economical over the long term.

Simple Installation: Includes pre-mounted Japan NSK sealed bearings for straightforward setup.

Bonus Inclusion: Comes with an additional five carbide inserts and screws for hassle-free future replacements.

Warranty Coverage: Enjoy a one-year limited warranty for the cutterblock.
