Straight Router Bits for Ceramics


With a diamond coating, these bits resist wear when used on ceramics and other highly abrasive material. All have a square cut style for creating slots, pockets, and edges. They do not have a pilot, so guide your router along a straight edge when hand routing to ensure straight, accurate cuts.

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.

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.
