Spiral Cutterheads Deliver Superior Performance


Spiral cutterheads are quieter, require less energy to operate and leave a smoother finish, with no tear-out, especially when it comes to figured woods. Each knife is staggered on the cutterhead and sits at a slight angle to produce a shearing cut. This combined shear and staggered cut eliminates tear-out and leaves glassy surface finish on even highly figured hardwood.

Sheartak cutterheads feature 15mm x 15mm x 2.5mm 4-sided inserts made of sintered tungsten carbide which is much harder than high speed steel, and are precision ground to a tolerance of +/-0.0004″ or +/-0.01mm. As a result, these cutterheads can last up to 10 times longer than straight high speed steel knives. And because spiral cutterheads produce thinner and shorter chips, dust extraction is more efficient.

Installing inserts is very easy. You simply loosen a screw, rotate the insert 90° for a new edge, and then re-tighten the insert.

Low cost to use, spiral cutterheads produce smoother finishes, reduce or eliminate sanding work, and don’t require sharpening.
