Solid Carbide Router Bit

This solid carbide router bit is built for cutting soft plastics. The O-flute upcut geometry clears chips efficiently and reduces heat build-up. It is intended for CNC routing and hand-held operations on plastic sheet and block.

For plastic fabrication, not metal

Makers and shops working with acrylic, polycarbonate or similar plastics will benefit from the upcut action. Users needing to machine aluminium, wood or composites should select a tool designed for those materials.

1/4 inch cutter diameter

The 1/4 in cutter diameter determines the minimum internal radius and the feed rates achievable. Verify that your collet and machine match this shank size before ordering.

Questions about this item

When will the carbide cutting edges on the 63-775 need replacement?

Replace the bit when the O-flute upcut edges show visible wear or when cut quality in soft plastic degrades.

What limits continuous routing with this 1/4 inch cutter?

Heat buildup in the solid carbide body and chip evacuation in the upcut flute limit sustained feed rates.

How much noise and heat does the 63-775 generate during all-day routing?

Expect typical high-speed router noise; the carbide body runs warm but stays within normal operating temperatures for hand-held use.
