With a 0.375-inch cutter diameter and a 0.625-inch length of cut, this single-edge bit provides controlled chip evacuation by pulling material up and away from the workpiece. The right-hand cutting direction and 21-degree helix angle work together to reduce heat buildup and minimize edge chipping on thermoplastics. The uncoated solid carbide construction delivers the sharp edge retention that plastic routing demands. Shank diameter is 3\/8 inch, making it compatible with standard router collets used in CNC and handheld routing setups. Licensed trades and skilled fabricators rely on this geometry for production-quality edges in demanding material applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for routing a wide range of thermoplastics and engineered plastic sheet materials in production and fabrication environments. Typical applications include profile cutting, slotting, and full-depth passes on plastic sheet stock. The upcut flute geometry is well suited to CNC router tables where chip clearance and surface finish are priorities. It performs across both light-duty fabrication shops and higher-volume production cells cutting flat plastic sheet.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for long edge life in abrasive thermoplastic materials\u003c\/li\u003e\n  \u003cli\u003eUpcut single-edge flute design pulls chips up and out of the cut for clean evacuation\u003c\/li\u003e\n  \u003cli\u003e21-degree helix angle reduces heat and chipping at the cut edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC and handheld router spindles\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains a sharp, true edge geometry without coating buildup\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank fits standard router collets without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in ABS, Acetal, Acrylic, HDPE, HIPS, PE, PET, Polycarbonate, Polypropylene, Polystyrene, Solid Surfaces, and UHMW.

Before changing or setting bits, ensure the router spindle is fully powered down and any CNC control is in an e-stop or tool-change state. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut per the router manufacturer specifications. Inspect the bit for edge chipping or cracking before each use and do not operate a damaged bit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.375 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: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 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\u003eBit Material\u003c\/strong\u003e: Solid Carbide\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: Single Edge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 21 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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: 63-750\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 63-780\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67906344386866,"sku":"63-780","price":110.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a6d17e5ac957f5126d7b0f6c28f50d1.jpg?v=1791167352","url":"https:\/\/voomisupply.com\/products\/onsrud-63-780-upcut-spiral-router-bit-3-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
