Solid-Carbide Spiral Bits

The full Schmidt spiral line, USA-made from micro-grain carbide: up-cut, down-cut, compression, and mortise-compression geometries backed by slow-spiral, chipbreaker, rougher, rougher/finisher, and laminate-grade series, plus O-flute, Z-flute, ball-end, and veining cutters for plastics, solid surface, and detail work. Narrow the 236 bits below by geometry, then cutting diameter (1/16"–3/4"), cut length (to 2-1/8"), shank (1/4"–3/4"), and flute count (one through four).

Laminate grade extends tool life in MDF under single- or double-sided laminate; chipbreakers and three-flute patterns hold finish at higher feed rates; roughers hog solid wood and composites, and slow spirals handle dense hardwood, solid surface, and hard plastics.
