The Shaper 1/4'' x 1'' Up-Spiral CNC Router Bit is similar to the stock 1/4'' cutter, but with the added benefit of a longer overall length and maximum depth of cut. This enables deeper passes and improved stability in deep channels. Made from solid carbide, with dual flute geometry, and compatibility with the standard Origin 1/4'' collet. Up-cut spiral pulls waste up and out of the cut for excellent chip clearance.
