Carbide Routing End Mill for Soft Plastic
The Onsrud 63-776 is a solid carbide router bit with an O-flute upcut spiral designed specifically for soft plastic applications. Its 1/4 inch cutter diameter and uncoated finish support clean chip evacuation in routing operations. This new tool targets fabricators and CNC operators cutting plastic sheet or block material.
Suited for plastic routing, not metal or heavy wood
Buyers machining aluminium, steel or dense hardwoods should select a different geometry and coating. The O-flute upcut is optimised for soft plastic chip removal and will not perform well in abrasive or ferrous materials. Shops needing a downcut action or a compression spiral for double-sided laminate must look elsewhere.
1/4 inch cutter diameter determines fit and finish
The 1/4 in cutting diameter sets the minimum inside radius and influences feed rates for the intended plastic work. Match this dimension to your tool holder and programmed toolpath to achieve the desired edge quality. No other size is offered under this model number.

Questions about this item
What shank diameter does the Onsrud 63-776 end mill need for my router collet?
The Onsrud 63-776 has a 1/4 inch cutter diameter, which typically matches a 1/4 inch shank for standard router collets.
How do I install the Onsrud 63-776 upcut bit without damaging the carbide flutes?
Insert the shank fully into the collet, tighten securely, and avoid over-tightening which can stress the solid carbide body.
When should I replace the Onsrud 63-776 carbide router bit?
Replace the bit when the upcut flutes show visible wear, chipping, or when cut quality declines in soft plastics.
