The upcut flute geometry pulls chips up and away from the workpiece, keeping the cut path clear and reducing heat buildup at the tip. With a 0.125-inch cutting diameter and a 0.5-inch length of cut, this bit is built for precise, small-diameter work in CNC router applications. The 1\/8-inch shank seats into standard collets at a 1.5-inch shank length, and the 21-degree right-hand helix produces a clean shear angle through common plastics. Installed by CNC machinists and fabrication shops working in production environments.\u003c\/p\u003e\n\u003cp\u003eThe 63-763 targets routing of thermoplastic materials including ABS, Acetal, Acrylic, HDPE, HIPS, PE, PET, Polycarbonate, Polypropylene, Polystyrene, Solid Surfaces, and UHMW. It is suited for slotting, profiling, and through-cutting operations where chip evacuation is critical to edge quality. The single-flute design runs at higher RPM with less chip load per pass, making it effective for thin-wall and detailed geometry work in plastic sheet fabrication. No pilot bearing is included, making this a freehand or fixture-guided CNC bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in continuous production routing\u003c\/li\u003e\n  \u003cli\u003eSingle-edge upcut flute evacuates chips upward, reducing re-cutting and heat at the workpiece\u003c\/li\u003e\n  \u003cli\u003e21-degree right-hand helix angle delivers a clean shear cut through thermoplastic materials\u003c\/li\u003e\n  \u003cli\u003e0.125-inch cutting diameter with 0.5-inch length of cut for tight-tolerance small-profile work\u003c\/li\u003e\n  \u003cli\u003e1.5-inch shank length provides secure collet engagement on standard CNC router spindles\u003c\/li\u003e\n  \u003cli\u003eUncoated carbide substrate compatible with a wide range of plastic material applications\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.

Seat the shank fully into a clean, undamaged 1\/8-inch collet and torque the collet nut to the router manufacturer's specification. Inspect the cutting edge and shank for runout or chipping before each production run. Do not exceed the router or spindle manufacturer's rated RPM for this shank diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.125 inches\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: 0.125 inches\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\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\u003eSeries\u003c\/strong\u003e: 63-750\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 63-763\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67911168491826,"sku":"63-763","price":69.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b563dac633e589d390e189fe4c8654e_fb9f9e03-d490-46e6-b18d-08b4d893a52b.jpg?v=1791205369","url":"https:\/\/voomisupply.com\/products\/onsrud-63-763-upcut-spiral-router-bit-0-125-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
