With a 0.125-inch cutting diameter and a 0.25-inch length of cut, this bit is built for detail work and tight-tolerance routing applications. The single-edge, right-hand upcut geometry pulls chips upward and away from the cut, keeping the work surface clean and reducing heat buildup. At 2 inches overall length with a 0.125-inch shank, it mounts directly into standard 1\/8-inch collet systems. Solid carbide construction delivers the hardness and edge retention needed for production routing in plastics.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for routing thermoplastics and engineered polymers including ABS, acetal, acrylic, HDPE, HIPS, PE, PET, polycarbonate, polypropylene, polystyrene, solid surfaces, and UHMW. It is well-suited for CNC router applications in sign-making, plastic fabrication, and light industrial production environments. The 21-degree helix angle is optimized for clean shearing cuts in these materials without melting or gumming the cutting edge. It is appropriate for both prototype runs and higher-volume production setups where chip evacuation and surface finish quality matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior hardness and edge retention in abrasive plastic materials\u003c\/li\u003e\n  \u003cli\u003eUpcut spiral geometry evacuates chips upward, keeping the cut path clear and reducing heat\u003c\/li\u003e\n  \u003cli\u003e21-degree helix angle optimized for clean shearing cuts in thermoplastics and engineered polymers\u003c\/li\u003e\n  \u003cli\u003eSingle-edge design reduces cutting forces on thin or flexible workpieces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC router spindle rotation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for non-ferrous plastic applications where coating is not required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CNC routers and manual routing equipment fitted with a 1\/8-inch collet.

Insert the shank fully into the collet and tighten to the router manufacturer's specified torque using the appropriate collet wrench. Verify runout with a dial indicator before production use. Do not exceed the tool's rated depth of cut per pass for the material being processed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 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: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRouter Style\u003c\/strong\u003e: Single Edge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Upcut\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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 63-750\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: 63-761\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67911854686514,"sku":"63-761","price":71.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a6d17e5ac957f5126d7b0f6c28f50d1_f9529700-57bf-4f67-9e42-128f335447d4.jpg?v=1791221910","url":"https:\/\/voomisupply.com\/products\/onsrud-63-761-upcut-spiral-router-bit-0-125-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
