Solid carbide O-Flute router bit

This solid carbide O-Flute router bit is designed for machining hard and soft plastics. The straight flute geometry provides clean cuts in plastic sheet and block material. It is supplied new and uncoated for general-purpose routing work. The 1/4 inch cutter diameter suits a range of CNC and hand-held routers.

For plastic fabrication, not metal

Shops cutting acrylic, polycarbonate, HDPE or similar plastics will find the O-Flute design effective. It is not intended for aluminium, steel or wood, so metalworkers and woodworkers should select a different geometry. The uncoated carbide substrate lacks the wear resistance needed for abrasive composites.

1/4 inch cutter diameter

The single specification that determines fit is the 1/4 inch cutter diameter. Your tool holder or collet must accept this exact shank size for the bit to operate safely. Verify the machine’s collet capacity before ordering.
