With a 0.0625-inch (1\/16-inch) cutter diameter and a 0.25-inch length of cut, this single-edge bit is built for fine-detail routing passes where tight tolerances matter. The upcut flute geometry pulls chips up and out of the cut, reducing heat buildup and improving surface finish. A 21-degree helix angle and right-hand cutting direction make it suitable for controlled material removal in thin-wall and close-tolerance applications. This bit is installed and operated by CNC routing technicians and production machinists.\u003c\/p\u003e\n\u003cp\u003eThe 63-751 is suited for routing a wide range of thermoplastics and engineered sheet goods, including ABS, acetal, acrylic, HDPE, HIPS, PE, PET, polycarbonate, polypropylene, polystyrene, solid surfaces, and UHMW. It fits into 1\/8-inch shank collets on CNC routers and handheld routing setups. The 2-inch overall length and 1.75-inch shank length provide adequate reach for typical sheet material depths while maintaining rigidity at this small diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for durability and wear resistance in abrasive plastics\u003c\/li\u003e\n  \u003cli\u003eUpcut flute design evacuates chips away from the workpiece surface\u003c\/li\u003e\n  \u003cli\u003e21-degree helix angle optimized for thermoplastic routing\u003c\/li\u003e\n  \u003cli\u003eSingle-edge geometry for clean, controlled cuts at 0.0625-inch diameter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, compatible with standard CNC router spindles\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no coating delamination risk during regrind cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC routers and routing equipment fitted with 1\/8-inch shank collets.

Ensure the router spindle is fully powered down and locked out before inserting or removing the bit from the collet. Seat the shank fully into the collet and tighten to the router manufacturer's specified torque range for 1\/8-inch tooling. At 0.0625-inch diameter, feed rate and spindle speed must be carefully dialed in to avoid bit deflection or breakage  -  consult the router manufacturer and ONSRUD feed-and-speed data for this series before running production cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\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 (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.75 inches (1-3\/4 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\u003eSeries\u003c\/strong\u003e: 63-750\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 63-751\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67907352559922,"sku":"63-751","price":69.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f86c0687645819441bd78ac446dff3c7.jpg?v=1791178136","url":"https:\/\/voomisupply.com\/products\/onsrud-63-751-upcut-spiral-router-bit-0-0625-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
