With a 0.5-inch cutter diameter, a 1.125-inch length of cut, and a 3-inch overall length, this bit is sized for production cutting in natural wood, solid surfaces, and wood composites. The downcut flute geometry directs chips upward into the cut, reducing tearout and splintering on the top face of the workpiece. The 30-degree helix angle and double-edge configuration support clean, consistent chip evacuation at typical production feed rates.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for routing operations where surface finish on the top face is the priority, such as finish cuts on hardwood panels, solid surface countertop material, and laminated wood composites. It installs in any router with a 0.5-inch collet and accepts a 1.875-inch shank engagement depth. Woodworking shops, cabinet fabricators, and CNC operators working in residential and light commercial millwork environments are the typical end users. The uncoated solid carbide construction performs well in the abrasive conditions common to composite and engineered wood materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDowncut flute geometry reduces tearout on the top face of the workpiece\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides hardness and edge retention in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle supports smooth chip flow and consistent cut quality\u003c\/li\u003e\n  \u003cli\u003eDouble-edge design for balanced cutting forces during routing passes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard router spindle rotation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for natural wood, solid surfaces, and wood composites\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in routers equipped with a 0.5-inch collet.

Insert the shank fully into the collet to the recommended engagement depth before tightening to the router manufacturer torque specification. Inspect the collet and collet nut for wear before each installation. Eye and hearing protection are required during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Downcut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRouter Style\u003c\/strong\u003e: Double Edge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Natural Wood, Solid Surfaces, Wood Composites\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiloted\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.26 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 57-200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ONSRUD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 57-360\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67911043416370,"sku":"57-360","price":168.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b1fb4dbcaf9de9e4b6e3b5761d00457_d8653ea5-5a4c-49ed-93f3-dcff343c2e56.jpg?v=1791203565","url":"https:\/\/voomisupply.com\/products\/onsrud-57-360-downcut-spiral-router-bit-0-5-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
