Amana Spoilboard CNC Router Bits

These durable, carbide-tipped bits are perfect for quick material removal on large surfaces, leaving a smooth finish while the deep flutes facilitate effective dust extraction.

The 1 1/8" diameter bit is triple-fluted, with a 1/4" shank and works particularly well for spoilboard surfacing on CNC machines with average bed sizes.

The 1 1/2" diameter bit has four flutes and a 1/2" shank, and is ideal for spoilboard surfacing on CNC machines with larger beds and more powerful spindle motors.

Both bits are excellent for flattening workpieces.
