The 0.25-inch cutting diameter, 0.75-inch length of cut, and 21-degree helix angle work together to shear material cleanly and evacuate chips upward out of the cut, reducing heat buildup and improving edge quality. The right-hand cutting direction and single-edge geometry allow faster feed rates in softer materials without loading the flute. This bit is sized with a 0.25-inch shank for use in standard collets on CNC routers and handheld laminate trimmers. It is installed and operated by CNC machinists, tooling technicians, and fabricators working in production and prototyping environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in plastics fabrication applications. Compatible materials include ABS, Acetal, Acrylic, HDPE, HIPS, PE, PET, Polycarbonate, Polypropylene, Polystyrene, Solid Surfaces, and UHMW. The upcut geometry makes it well-suited for through-cuts and profiling operations where chip evacuation is critical to surface finish. It is commonly used in sign fabrication, point-of-purchase display production, and light industrial plastic sheet processing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in abrasive thermoplastics\u003c\/li\u003e\n  \u003cli\u003eSingle-edge upcut geometry evacuates chips upward, reducing recutting and heat\u003c\/li\u003e\n  \u003cli\u003e21-degree helix angle optimized for clean shearing action in plastics\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 plastic materials that do not require specialized coatings\u003c\/li\u003e\n  \u003cli\u003e0.25-inch shank fits standard collets on most CNC routers and trim routers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC routers and handheld trim routers equipped with a 0.25-inch collet.

Power down and lock out the spindle before changing tooling. Seat the shank fully into the collet and tighten to the collet manufacturer's specification before operation. Inspect the cutting edge for chips or wear before each use, as solid carbide is brittle and damage is not always visible to the naked eye.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 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\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\u003eSeries\u003c\/strong\u003e: 63-750\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 63-775\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67912559624498,"sku":"63-775","price":76.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a6d17e5ac957f5126d7b0f6c28f50d1_c6110f9d-b614-4a5f-9cf8-ef58ebd5a99c.jpg?v=1791235988","url":"https:\/\/voomisupply.com\/products\/onsrud-63-775-upcut-spiral-router-bit-0-25-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
