Onsrud Down-Cut Spiral Router Bits

Down-shear spiral action prevents chip-out and fuzzing at the edge of the cut—ideal for cutting clean dados, grooves and rabbets.
Item #
GRP11263

Down-spiral cutting action forces the chips down into the groove, eliminating the tendency for wood fibers to chip out the face. Double-flute design with HSS (high speed steel) construction for a smooth finish.


Recommended when chip flow should be directed down for a clean cut on top of the material.
