Whiteside Machine Up/Down Compression Spiral Bits

Thank you for shopping with us!

Made from solid carbide, each bit contains an upcut and a downcut flute, creating a compression cut that prevents fraying & splintering. Compression spirals will save you time and money on finishing your project edges by reducing sanding time.

Solid Carbide is not guaranteed against breakage.
