With a 0.125-inch cutter diameter, a 0.5-inch length of cut, and a 21-degree helix angle, it delivers clean chip evacuation and precise cutting geometry in demanding CNC and handheld routing applications. The single-edge, right-hand cutting configuration suits situations where upward chip pull and reduced heat buildup are priorities. Machinists and CNC operators working in plastics fabrication and composites shops rely on this size and style for detail routing and slot work.\u003c\/p\u003e\u003cp\u003eThe 63-712 is suited for residential and commercial fabrication environments where hard thermoplastics and engineered solid surfaces are processed. Typical applications include routing acrylic sheet, nylon stock, PVC profiles, and polycarbonate panels. The 0.125-inch diameter makes it well suited for narrow slot cutting, edge finishing, and detail profiling passes on CNC routers. The 1\/4-inch shank diameter fits standard collet systems on most production and benchtop CNC routers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in hard plastic and engineered material applications\u003c\/li\u003e\n\u003cli\u003eUpcut flute geometry pulls chips away from the workpiece and reduces heat accumulation at the cut\u003c\/li\u003e\n\u003cli\u003e21-degree helix angle optimized for clean edge quality in acrylic, nylon, PVC, and polycarbonate\u003c\/li\u003e\n\u003cli\u003eSingle-edge router style for precise material removal in narrow-kerf applications\u003c\/li\u003e\n\u003cli\u003eUncoated finish  -  no coating interference when working with materials sensitive to contamination\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC router spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with material applications including acrylic, nylon, PVC, polycarbonate, and solid surfaces.

Power down and de-energize the spindle completely before inserting or removing the bit from the collet. Secure the shank fully into the collet to the recommended engagement depth before tightening  -  never leave less than two-thirds of the shank length engaged. Inspect the cutting edge for chips or wear before each use, as carbide tooling in hard materials is subject to edge micro-fracture if run at incorrect feeds and speeds.\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: 0.25 inches (1\/4 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: Upcut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRouter Style\u003c\/strong\u003e: Single Edge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 21 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Acrylic, Nylon, PVC, Polycarbonate, Solid Surfaces\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: 63-700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 63-712\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67907221750066,"sku":"63-712","price":76.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed8fdc6c8c5a2d61a19e6c456f318ddd.jpg?v=1791175768","url":"https:\/\/voomisupply.com\/products\/onsrud-63-712-spiral-upcut-router-bit-1-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
