With a 0.75 inch cutter diameter and a 3.125 inch length of cut, it handles deep passes in materials like ABS, acrylic, polycarbonate, HDPE, UHMW, nylon, PET, acetal, and PE. The double-edge, right-hand cutting geometry combined with an 11-degree helix angle promotes chip evacuation and a clean finish. At 0.74 pounds, the bit mounts on a 0.75 inch shank and is part of the 52-600 series. This bit is installed by CNC machine operators and tooling technicians working with plastic fabrication and machining applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for routing and profiling operations in hard and soft plastics and solid surface materials in both production shop and job-site environments. Typical applications include panel cutting, edge profiling, and through-cuts in thermoplastic sheet goods. The upcut flute style pulls chips up and out of the cut, reducing heat buildup and recutting in deep-pocket and through-cut scenarios. The 6 inch overall length provides clearance for thicker workpieces and deep fixture setups common in CNC router tables.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for durability and edge retention in abrasive plastic materials\u003c\/li\u003e\n  \u003cli\u003eUpcut flute geometry promotes chip evacuation and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003e11-degree helix angle optimized for hard and soft plastics and solid surfaces\u003c\/li\u003e\n  \u003cli\u003eDouble-edge router style for efficient material removal\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no coating buildup risk on heat-sensitive thermoplastics\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC and handheld router spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with materials including ABS, acetal, acrylic, HDPE, hard and soft plastics, nylon, PE, PET, polycarbonate, solid surfaces, and UHMW.

Power down and lock out the spindle before inserting or removing the bit. Seat the shank fully into the collet and torque the collet nut per the router or CNC manufacturer specifications. Verify spindle speed settings are appropriate for the target material and bit diameter before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.875 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: Double 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: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 52-600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.74 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: 52-664\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67914136453426,"sku":"52-664","price":601.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/128356f074b7dc0aa346e97bf151e959_a15cc2ac-b8cc-4190-b32f-cefe6c3edffd.jpg?v=1791247454","url":"https:\/\/voomisupply.com\/products\/onsrud-52-664-upcut-spiral-router-bit-0-75-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
