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.

Trimming Router Bits
Cut layers of material flush to one another or make cuts along a template.
Use carbide bits for longer tool life and faster cutting speeds than high-speed steel. Ball-bearing pilots guide the bit for accurate cuts and produce less friction than solid pilots for smoother operation.
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.
Bits with spiral flutes leave a smoother finish than straight-flute bits and make plunge cuts more easily (for plunge-cutting bits).

Diamond-Coated Router Bits for Composites
With a diamond coating, these bits resist wear when used on abrasive materials, making them last about 50 times longer than uncoated bits. Their sharp cutting edges and flute shapes are specifically designed to cut through tough materials such as composites with minimal resistance. This means less strain on your router and more control when cutting, leading to a smooth cut. Bits are made of solid carbide for longer tool life and faster cutting speeds than high-speed steel.
Straight Flutes—For general purpose use. They quickly remove material, leaving a rough finish.
Spiral Flutes—Leave a smoother finish than straight-flute bits and make plunge cuts more easily (for plunge-cutting bits).
Use bits with a square cut style to cut slots, pockets, and edges. Bits with a drill/mill cut style have a pointed end for easier plunge cuts than square-cut bits.
Plunge-cutting bits let you cut directly into the workpiece from above. Other bits are best for operations where the peripheral teeth do most of the work such as trimming, contouring, and finishing.
Bits with upward and downward chip removal are also known as compression bits. Acting similar to scissors, they move chips away from the top and bottom edges of the cut for a smooth finish on both. Bits with higher compression angles cut more efficiently than bits with lower compression angles, reducing the amount of force required to cut through your material. They are also more resistant to wear.

Plotter Pen Router Bits
Test new designs without ruining your material—these bits hold a pen rather than a blade, so you can trace a CNC machine’s path before you cut. Spot errors, adjust your design, and trace again. For repeat testing on metal, glass, and plastic, you can wipe the ink off with acetone. Turn your spindle off to hold the marker steady and draw clean lines.

Router Bits for Thin Materials
Make shallow incisions in fabric, leather, and rubber. Unlike other router bits, these bits do not spin or rotate; instead, the blade follows the motion of the CNC machine, behaving like a rudder as it cuts through material. These bits are plunge cutting, letting you cut directly into the workpiece from above.
Carbide bits have a small, sharp point for cutting precise, thin lines. They’re spring loaded to apply constant pressure to the tip, making them good for cutting thinner materials than steel bits.
Steel bits use a utility-knife blade; the larger blade cuts through thicker materials than carbide bits.

Engraving Router Bits
A fine-point diamond tip precisely cuts lettering, numbering, and grade marks in materials such as aluminum, steel, copper, and granite. These bits also work on plastics such as polyethylene, polycarbonate, and vinyl. They’re spring loaded to apply constant pressure to the tip.
Use 90° cut angle tips (sold separately) to engrave the finest details.

Router Bit Sets
Keep a variety of router bits on hand to cut grooves, chamfers, and other detailed shapes into wood and plastic. Made of carbide-tipped high-speed steel, these bits provide a longer tool life and faster cutting speeds than standard high-speed steel bits.
Flush-trimming bits cut layers of material flush to one another or make cuts along a template.
Joining bits create shapes that fit together in order to form joints.
Hinge-mortise bits create large, shallow recesses.
Panel-pilot bits have a pointed tip that creates starter holes for efficient plunge cutting in wood. To make precise cutouts, use the top of the tip as a pilot and guide the bit along a template placed below the workpiece.
