Solid Carbide Router Bit

The Onsrud 52-285 is a solid carbide routing end mill with an upcut spiral flute. It is built for CNC routing operations that need clean chip evacuation and a smooth finish on the top surface. The 1/4 inch cutting diameter suits detailed profiling, pocketing and slotting tasks. This tool is aimed at professional woodworkers and sign makers running CNC routers.

Best for Wood and MDF Cutting

The bit is specified for primary use in MDF and wood where upward chip removal prevents dust packing in the cut. It is not suited for machining ferrous metals, hardened steels or abrasive composites that would wear carbide quickly. Buyers who need a downcut or compression spiral for double-sided laminate surfaces should look at a different geometry. Hand-held router users without a rigid CNC spindle may also find the upcut pull difficult to control.

1/4 Inch Cutting Diameter

The 1/4 inch cutter diameter is the single dimension that decides whether this bit fits the programmed toolpath and the machine's tool holder. Verify the shank diameter matches your collet size before ordering. A mismatch here means the tool cannot be held or will cut the wrong width. No other specification overrides this fit requirement.
