Constructed from solid carbide, the bit offers the rigidity and edge retention needed for clean, consistent cuts in production routing applications. The 0.5-inch cutting diameter pairs with a 1.625-inch length of cut and a 0.5-inch shank diameter, making it a practical choice for both CNC routing tables and hand-held router setups where precise plastic machining is required. The 21-degree helix angle and right-hand cutting direction promote efficient chip evacuation upward and away from the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for use on thermoplastics and engineered plastics including ABS, Acetal, Acrylic, HDPE, HIPS, PE, PET, Polycarbonate, Polypropylene, Polystyrene, UHMW, and Solid Surfaces. It is well suited for fabrication shops, sign makers, and industrial routing operations where clean edge quality and minimal melting or chipping in plastic substrates are priorities. The uncoated solid carbide construction keeps the cutting edge sharp through extended run cycles on abrasive plastics.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and long edge life in plastic routing\u003c\/li\u003e\n  \u003cli\u003eUpcut flute geometry evacuates chips upward to reduce recutting and heat buildup\u003c\/li\u003e\n  \u003cli\u003e21-degree helix angle optimized for thermoplastic materials\u003c\/li\u003e\n  \u003cli\u003eSingle-edge design for aggressive feed rates and clean finishes in soft plastics\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC and handheld router setups\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains sharp cutting edge without coating interference on plastics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with routers accepting a 0.5-inch shank collet.

Ensure the router is fully powered down and the collet is fully de-energized before inserting or removing the bit. Insert the shank fully into the collet and tighten to the router or collet manufacturer specifications. Verify spindle speed and feed rate are appropriate for the specific plastic material being cut before starting the machine.\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\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\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: 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\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\u003eMaterial Application\u003c\/strong\u003e: ABS, Acetal, Acrylic, HDPE, HIPS, PE, PET, Polycarbonate, Polypropylene, Polystyrene, Solid Surfaces, UHMW\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: 0.25 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: 63-790\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67912001945906,"sku":"63-790","price":260.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ceb57a175cd07d3e884689eab4fabfa.jpg?v=1791224744","url":"https:\/\/voomisupply.com\/products\/onsrud-63-790-upcut-spiral-router-bit-0-5in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
