The downcut flute geometry drives chips downward during cutting, which suppresses surface tearout and keeps the top face of the workpiece clean. With a 0.125-inch cutter diameter, a 0.5-inch length of cut, and a right-hand cutting direction, this bit is built for precision routing in tight geometries. It is suited for CNC router applications where surface finish quality and dimensional accuracy are critical. The 30-degree helix angle and double-edge design support efficient chip evacuation at typical routing feed rates.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use in CNC routing operations on natural wood, solid surface materials, and wood composites. Its 1\/8-inch shank diameter fits standard 1\/8-inch collets found on compact and full-size CNC router spindles. Typical applications include detail routing, profile work, and surface finishing passes where tearout control on the top face of the material is a priority. The uncoated solid carbide construction is appropriate for clean, non-abrasive materials in the listed application categories.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDowncut flute geometry minimizes surface tearout on the top face of the workpiece\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and edge retention in wood and solid surface routing\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with double-edge design for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC router spindles\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank fits common CNC collet sizes without an adapter\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for natural wood, solid surfaces, and wood composites\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC routers equipped with a 1\/8-inch collet.

Power down and lock out the spindle before inserting or removing the bit. Ensure the shank is fully seated and the collet nut is properly torqued per the router manufacturer's specification before operation. Do not exceed the router spindle's rated RPM range for the cutter diameter in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Material\u003c\/strong\u003e: Solid Carbide\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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eSeries\u003c\/strong\u003e: 57-200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 57-244\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67910976143666,"sku":"57-244","price":68.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ea87ab8476ee2fdf9e8c89fb736b858.jpg?v=1791202452","url":"https:\/\/voomisupply.com\/products\/onsrud-57-244-downcut-spiral-router-bit-1-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
