Screw On Helix Mortise Cutters
If you cut a lot of mortises nothing is better than the screw type helix mortise cutters with a downshear angle. With the screw on cutter, once the cutter gets dull all you have to do is replace just the cutter and reuse the same arbor saving cost.
All of our router bits are Made in USA by the award winning Whiteside Machine in their North Carolina factory.
