In this extensive episode of The Router Bits, Patrick Holcombe discusses and demonstrates the real advantages of Spiral Router bits. If you haven't discovered them for yourself, then this video is worth watching...
Upcut spiral bits are so-called because when used handheld have upward chip ejection providing an excellent finish on the lower side of the workpiece. When used in a router this action is reversed, the waste is ejected under the table with an excellent finish on the upper side of the work piece.
Due to their spiral cutting edge which stays in continuous contact with the workpiece, these bits give a smooth, chatter-free cutting action, unlike conventional bits which have intermittent contact with the workpiece. Unsurpassed for cleaner cuts in ordinary or difficult materials, softwood, hardwood, plywood, composites etc.
A special super-micrograin carbide formulation was created to produce and hold a keen cutting edge. The new low-angle spiral is designed specifically to shear wood cleanly and provide efficient chip ejection. The tools run cooler and the edges last longer.
Downcut spiral bits are so-called because when used handheld have downward chip ejection providing an excellent finish on the upper side of the workpiece. When used in a router this action is reversed, the waste is ejected above the table and bit with an excellent finish on the lower side of the work piece. To note that when used for trenching operations, this can cause the router/work piece to lift due to the waste collecting in the bottom of the trench.

Compression spiral bits are designed with both up and downcut chip ejection, providing an excellent finish on both the upper and the lower side of the workpiece.

The new CMT solid carbide spiral flush trim bits are manufactured with a special super-micrograin formulation that has increased hardness. Combined with the spiral cutting angle, the new CMT solid carbide spiral flush trim bits with double bearings allow the cabinet maker to sheer wood and other wood-based 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.
