Solid Carbide Router Bit

The Onsrud 52-325 is a solid carbide router bit with a 0.375 inch cutter diameter. It features an upcut spiral flute geometry designed for efficient chip evacuation. The tool is intended for routing operations in wood and MDF materials.

Suitable Materials and Limitations

This bit suits woodworkers and CNC operators cutting MDF or solid wood who need clean upward chip removal. It is not for users machining metals, plastics or abrasive composites that require different carbide grades or coatings. Buyers needing a downcut or compression spiral for top-surface finish should look elsewhere.

Cutter Diameter

The cutting diameter is 0.375 inch, which determines the minimum groove width and inside corner radius this tool can produce. Verify that your collet or tool holder accepts this shank size before purchase.

Questions about this item

Does the 52-325 router bit come with any collets, bearings or wrenches, or must those be purchased separately?

The 52-325 is supplied as a single solid carbide router bit. Collets, bearings, wrenches or any other accessories are not included and must be sourced separately.

Should I choose the 0.375 in cutter diameter or a different size for general MDF and wood routing?

The 0.375 in cutter diameter on the 52-325 suits general-purpose routing in MDF and wood. Select a different diameter only if your project specifically requires a wider or narrower cut.

What does the spiral upcut design on the 52-325 mean for chip removal when cutting MDF?

The spiral upcut geometry pulls chips up and out of the cut, giving cleaner edges in MDF and wood while reducing heat buildup during extended routing passes.
