Sheartak Spiral Cutterhead for FELDER Jointer Model 310 comes with a total 78 carbide inserts on 5 spirals. 5 extra carbide inserts and 5 screws are provided as spare parts. We ship by Canada Post, USPS, and UPS. Sheartak spiral cutterhead leaves a superior surface finish over straight-edge cutterheads. The round-edged inserts are angled for a shear-cut that leaves a glassy smooth cut even on highly figured woods or very soft wood. Each insert has four cutting edges and can be rotated up to 3 times to reveal a fresh sharp edge. No more sharpening and resetting when an insert gets dull or nicked. Carbide inserts stay sharp 50 times longer than HSS blades. Dust extraction is much easier with the shorter and thinner chips cut by Sheartak spiral cutterheads.
