Spiral-flute bits combine a shearing action in cutting with an augering action in chip clearance. The shearing action yields an especially clean & accurate cut, while the augering action clears chips from the cut.
The “up-cut” shears from the bottom up, pulling chips from the bottom
up, thus allowing deeper penetration with less stress on the tool. An
excellent choice for mortising. Special unique carbide grade, increased clearance geometry and razor-sharp cutting edges with polish flutes provides a superior finish and longer tool life. Special unique carbide grade for longer lifetime in abrasive materials.
These bits are great for production settings and excellent for creating grooves and dado cuts in softwood, hardwoods, plywood and composite materials. Primarily used on CNC machines and other automatic routers. Also can be used with hand-held and table-mounted portable routers. |
