Oliver has been manufacturing industry leading planers and jointers for over a century. We have also been outfitting our machines with our own brand of high quality helical cutterheads and inserts for over 20 years. Our manufacturing experience and knowledge of cutterhead technology is used in our HCX cutterheads for our entire product line of planer and jointer machinery.
What is a helical cutterhead and why does it matter to your wood shop? Helical means it has teeth arranged in a spiral pattern around the cutterhead, similar to a spiral staircase. This design helps make smoother cuts, reduces noise and clears material more efficiently.
Helical cutterheads also provide a shearing action which allows the teeth (four-sided inserts) to slice through the wood fibers like scissors cutting paper at slight angles, rather than just smashing through them at a right angle.
This combination of helical and shearing action results in cleaner, more precise cuts with less tear-out, less wear and a better overall finish needing less sanding. The added benefit is the inserts themselves are four-sided, letting you easily rotate them individually as they wear or get damaged.
Our four-sided carbide inserts provide quality cuts and a long service life, reducing the frequency of blade changes. The Oliver HCX Helical cutterheads and inserts are engineered to give the smoothest finish and longest life in our machines working with the toughest hardwoods, providing consistent and superior results with each pass.
