Description
Spiral Router Bits are straight bits that have the added advantage of a making a continuous shearing cut with higher efficiency and less tearout. An upcut spiral also allows better chip removal when routing mortises than an ordinary straight bit.
Up-cut spiral bitsare excellent for use in a router table where the cutting action itself helps hold the workpiece to the table. They are excellent for cutting mortise and tenons, grooving and slotting.
All bits are two flute, solid carbide.
