The upcut flute geometry pulls chips up and out of the cut, reducing heat buildup and keeping the work path clear. With a 0.1563-inch cutter diameter, a 0.625-inch length of cut, and a 30-degree helix angle, this bit delivers controlled material removal in narrow slot and profile operations. The double-edge design provides balanced cutting action across a range of feed rates. It is sized for a 1\/4-inch shank and is part of the ONSRUD 52-200 series.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for CNC routing and hand-held router applications where a small-diameter, high-precision cut is required. Typical applications include slotting, profiling, and plunge cutting in natural wood, MDF, plywood, acrylic, PVC, and solid surface materials. The compact 0.1563-inch diameter makes it well suited for fine detail work, narrow channels, and intricate pattern routing in both production shop and custom fabrication environments. The 2-inch overall length provides enough clearance for most standard router collet setups with a 1\/4-inch chuck.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life and heat resistance\u003c\/li\u003e\n  \u003cli\u003eUpcut flute geometry evacuates chips efficiently, reducing recutting and heat\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle for smooth cutting action across multiple materials\u003c\/li\u003e\n  \u003cli\u003eDouble-edge (2-flute) design balances cutting forces at the tip\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no coating buildup to affect tight-tolerance cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, compatible with standard router spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/4-inch collet routers and CNC spindles.

Always power down and lock out the router or spindle before changing bits. Insert the shank fully into the collet and tighten to the router or spindle manufacturer's specified torque range  -  do not exceed maximum shank engagement depth. Verify spindle speed and feed rate are appropriate for the material and bit diameter before running the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 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: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 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: Upcut\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, Plastics, 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: 52-200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: 52-250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67911070253362,"sku":"52-250","price":66.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1335afdc1f3f7b07ecb47a23ec5028b7.jpg?v=1791203949","url":"https:\/\/voomisupply.com\/products\/onsrud-52-250-upcut-spiral-router-bit-0-1563-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
