If a planer/jointer (felder AD 741) is currently struggling with depth of cut more than 1/32-1/16" with the stock 2 edge replaceable straight knife setup, would it struggle more or less with a sheartak head? Its really a dog in planer mode for such a large machine in its price range.
It would struggle more according to the video. The AD741 is a good machine, but the motor must be undersized. Maybe you could upgrade the motor. I think they offer 4, 5.5, 7.5 and 10hp motors for them.
Thank you for your comment! Spiral cutter heads, featuring individual carbide inserts, are highly effective at shear cutting and minimizing tear-out. The precise placement of each carbide insert enables a slicing motion, leading to smoother cuts and a reduction in tear-out. If you're interested, we have another video that provides a visual comparison of these cutter heads. You can check it out here: ua-cam.com/video/Y4r_H1RwE7k/v-deo.html
Helical heads and spiral heads are different. Helical - inserts are rotated around the cutterhead block, but seated square to the material edge. Spiral - inserts are rotated around the cutter head, but seated at an angle to the material edge creating a shear cut on the material, which is much better.
@TurdFerguson149 nope, straight from Sheartak's info... Spiral cutterheads utilize carbide inserts with round edges at varying radii, such as R150 and R100, with the most common size being 15x15x2.5mm (as shown in Fig. 3). The inserts are angled to the board's feeding direction, allowing for a shear-cut. In contrast, helical cutterheads use straight-edged carbide inserts that are square (90°) to the feeding direction. Popular sizes for this type of cutterhead include 14x14x2mm or 15x15x2.5mm. The helical cutterhead directly cuts materials without a shear cut.
Thank you very much👍

How does this compare to a helical cutter head?

What they are calling a spiral cutterhead is the same thing as a helical cutter head. The blades are angled to shear cut.

@@the-wooden-beard I think you got that backwards
