Ultimate Compression Spiral Sc Up/Down Bit 1/2Sh 3/8 Cd 1/2 Cl 3 Oal
These Ultimate Carbide Compression Spiral bits are designed for CNC and ideal for routing plywood and MDF. Where most standard compression spirals push the chips to the center of the cut where the up-cut and down-cut spirals meet, the Ultimate compression bits have an upcut flute that extends into the shank for better chip evacuation. This unique design of the Ultimate Compression Spirals allows you to run them faster and cooler than standard Compression spirals, giving you longer tool life. The 3/8" cut diameter is optimal for sheet goods and can remove less material with lower horsepower than the 1/2" diameter bits.
