It features a 0.1875-inch cutter diameter, a 0.625-inch length of cut, and a 21-degree helix angle. The downcut flute geometry pulls chips downward during the cut, which helps reduce surface tearout and delamination on the top face of the workpiece. At 2 inches overall length with a 1.375-inch shank, this bit is sized for compact, controlled routing passes. Sold uncoated and designed for right-hand cutting direction, it is well suited to CNC routing operations where edge quality on plastics is the priority.\u003c\/p\u003e\n\u003cp\u003eThe 62-719 is intended for use in hard material applications including acrylic, nylon, PVC, polycarbonate, and solid surfaces. It fits standard 3\/16-inch collets and is a practical choice for production shops and fabricators routing plastic sheet goods, thermoformed panels, and similar engineered materials. The single-edge geometry allows for higher chip loads per flute, which can improve finish quality and reduce heat buildup in thermoplastic materials. Typical applications include profiling, slotting, and edge routing on CNC router tables in light manufacturing and sign fabrication environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDowncut flute direction reduces top-surface tearout on plastics\u003c\/li\u003e\n  \u003cli\u003eSingle-edge geometry supports higher chip load and cleaner cuts in thermoplastics\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e21-degree helix angle optimized for hard plastic materials\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no coating thickness variation affecting tolerances\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC routers equipped with a 3\/16-inch collet.

Ensure the router spindle is fully powered down and locked out before changing bits. Insert the shank fully into the collet to the recommended engagement depth and torque the collet nut to the machine manufacturer's specification. Verify runout with a dial indicator before running production cuts, particularly at small diameters where deflection is a concern.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 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: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 inches (1-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 21 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: 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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (Acrylic, Nylon, PVC, Polycarbonate, Solid Surfaces)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 62-700\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: 62-719\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67916425363762,"sku":"62-719","price":73.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae4e1ec0827c0cc037013f3f007ff403.jpg?v=1791257889","url":"https:\/\/voomisupply.com\/products\/onsrud-62-719-downcut-spiral-router-bit-3-16-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
