The downcut helix  -  cut at a 21-degree helix angle  -  directs chips downward during the cut, suppressing surface tear-out on the top face of the workpiece and producing clean, burr-free edges on sheet plastics. It carries a 0.5-inch cutter diameter and a 1.625-inch length of cut, mounted on a 0.5-inch shank. This bit is uncoated and ground for right-hand cutting direction. It is sized and specified for professional CNC router use in fabrication and production environments.\u003c\/p\u003e\n\u003cp\u003eThe 62-790 is designed for routing thermoplastics and engineered plastics commonly processed on CNC routing tables in sign shops, fabrication shops, and plastic component production lines. Approved material applications include ABS, Acetal, Acrylic, HDPE, HIPS, PE, PET, Polycarbonate, Polypropylene, Polystyrene, Solid Surfaces, and UHMW. The downcut geometry is especially useful when surface finish on the entry face is critical or when the workpiece cannot be securely clamped flat without risk of lifting. Part of the ONSRUD 62-750 series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDowncut flute geometry minimizes top-face tear-out on plastics\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for wear resistance in abrasive thermoplastic materials\u003c\/li\u003e\n  \u003cli\u003e21-degree helix angle engineered for clean chip evacuation in plastic routing\u003c\/li\u003e\n  \u003cli\u003eSingle-edge design reduces heat buildup during continuous cutting passes\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no coating to chip or delaminate during regrinding\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; compatible with standard CNC router spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in ABS, Acetal, Acrylic, HDPE, HIPS, PE, PET, Polycarbonate, Polypropylene, Polystyrene, Solid Surfaces, and UHMW.

Power down and lock out the spindle before changing tooling. Insert the shank fully into the collet to the minimum engagement depth specified by the router manufacturer  -  never run a bit with insufficient shank engagement. Verify spindle speed and feed rate against the material being cut before beginning a production run.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\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\u003ePiloted\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 62-750\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 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: 62-790\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67906839380274,"sku":"62-790","price":287.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23afbecfefb895850c8dd8bbeb6db587.jpg?v=1791171952","url":"https:\/\/voomisupply.com\/products\/onsrud-62-790-downcut-spiral-router-bit-0-5-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
