Router Bit for MDF and Wood

The Onsrud 57-367 is a solid carbide router bit built for cutting MDF and wood. Its 1/2 inch cutter diameter and downcut spiral geometry push chips downward for a clean top surface. This tool suits CNC operators and woodworkers who need precise edge quality on sheet goods. It is not intended for metal, plastic or abrasive composite materials.

Downcut Spiral Geometry

The downcut spiral forces waste toward the workpiece instead of lifting it, which reduces tear-out on veneered or laminated panels. This cutting action also holds thin material flatter against the spoil board during profiling. The design does not evacuate chips upward, so deep slots or high feed rates may require adjusted chip-load strategies.

Carbide Construction and Shank Fit

Solid carbide construction resists wear on abrasive MDF binders and maintains sharpness longer than high-speed steel alternatives. The bit fits standard 1/2 inch collets for direct mounting in most CNC routers and handheld machines. No proprietary holders or adapters are needed, simplifying tool changes in production environments.

Questions about this item

When will the 1/2 in carbide cutter on this Onsrud 57-367 need replacement?

Replace the carbide cutter when the downcut edges dull from MDF or wood routing, shown by tear-out or increased feed force.

What limits continuous routing with this 57-367 downcut bit?

Heat buildup in the solid carbide body during sustained cuts in MDF or wood is the first limit, requiring cool-down pauses.

How much noise and heat does this router bit generate during all-day use?

The downcut spiral produces typical high-speed routing noise; the solid carbide body conducts heat into the workpiece during extended MDF or wood cuts.
