Great for combined plunge-cutting and pattern/ template routing. Extra long Cutter for multiple or extra-thick stock. For increased work piece visibility, use the top bearing flush trim Bit in a handheld router allowing the template to be positioned on top of the work piece. In a router table, template will be positioned underneath the work piece. Can be used without the bearing as a standard straight bit. Two flute carbide cutters with enclosed ball bearing. 1/2" Shank.
