Spiral Router Bits for Foam
The cutting edges of these bits have a shallow angle to carve foam quickly and accurately. With a square cut style, they create slots, pockets, and edges. Their spiral flutes leave a smooth finish and are good for making plunge cuts. All are made of solid carbide for a long tool life and fast cutting speeds. The extreme hardness of carbide bits means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the bit from breaking.
Bits with upward chip removal lift chips up for applications that need a smooth finish on the bottom edge of the cut. Securely clamp your workpiece in place before routing to prevent the piece from lifting.
Bits with downward chip removal push chips down for applications that require a smooth finish on the cut’s top edge.

Flush-Trimming Router Bits
Cut layers of material flush to one another or make cuts along a template. All bits have a pilot to guide cuts.
Pilot location describes the position of the pilot when the bit is used for hand routing. The pilot location is reversed when using the bit with a router table.
Bottom-pilot bits trim material from an upper layer of the workpiece so that it is flush with the layer below. In addition to flush trimming, they can be used to cut along a template placed below the workpiece. Micrograin carbide and diamond-tipped carbide bits are for use on aluminum.
