The new CMT solid carbide spiral flush trim bits are manufactured with a special super-micrograin formulation that has increased hardness with a higher transverse rupture point. Combined with the low helix cutting angle, the new CMT solid carbide spiral flush trim bits with double bearing allow the cabinet maker to sheer wood and wood products cleanly, providing more efficient chip ejection than standard flush trim bits. In production settings these new bits will run cooler and the edges will stay sharper, last longer and increase your shop productivity.
