Solid Carbide Router Bit
This solid carbide router bit features an O-flute upcut spiral design intended for soft plastic applications. The 1/8 inch cutter diameter and uncoated finish support clean chip evacuation in plastic sheet or block stock. It is built for CNC routing and hand-held operations where a sharp edge and upward chip flow are required. The Onsrud 63-763 suits fabricators and sign makers cutting acrylic, HDPE or similar thermoplastics.
Soft plastic routing only
The upcut geometry pulls chips upward, which helps prevent re-cutting in soft plastics but can lift thin workpieces or cause tear-out on brittle materials like phenolic or fibreglass. Buyers needing downcut or compression spirals for double-sided laminate, hardwood or aluminium should look at alternative flute styles. This bit is not suited for high-volume production runs that demand coated tooling for extended life.
1/8 inch cutter diameter
The cutting diameter of 1/8 inch determines the minimum internal corner radius and the width of the kerf in your toolpath. Verify that your collet or tool holder accepts the shank size before ordering. If your design requires a larger or smaller kerf, select a bit with a different cutter diameter.

Questions about this item
Will the 1/8-inch cutter diameter work with the collet on my older CNC router?
The solid carbide bit has a 1/8-inch cutting diameter; check your machine's collet size to confirm fit.
How do I verify the upcut O-flute is clearing chips properly during the first cuts?
Watch for clean chip ejection and a smooth finish on soft plastic — the upcut spiral should pull debris upward.
Does the box include any collets, wrenches or lubricants, or are those separate purchases?
Only the uncoated carbide router bit is supplied; collets, wrenches and cutting fluid must be sourced separately.
