With a 3\/16-inch (0.1875 inch) cutter diameter and a 1.625-inch length of cut, this bit removes chips aggressively by pulling them upward and out of the cut. The 25-degree helix angle promotes clean chip evacuation, which helps maintain cut quality in low-density foam applications. The double-edge design provides stable cutting geometry. At 3 inches overall length with a 2.375-inch shank length, the 52-560 fits standard router collets and CNC spindles. It ships uncoated and requires no pilot bearing.\u003c\/p\u003e\u003cp\u003eThis bit is suited for routing, profiling, and trimming foam  -  including expanded polystyrene (EPS), polyurethane, and similar soft materials  -  in CNC routing and hand-router applications. Typical users include sign makers, packaging fabricators, and composite panel shops. The upcut flute geometry is especially useful when through-cuts are required and chip buildup in the kerf is a concern. The right-hand cutting direction is standard for conventional CNC spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for wear resistance in abrasive foam materials\u003c\/li\u003e\n\u003cli\u003eUpcut flute geometry pulls chips up and out of the cut, reducing re-cutting\u003c\/li\u003e\n\u003cli\u003e25-degree helix angle promotes aggressive chip evacuation\u003c\/li\u003e\n\u003cli\u003eDouble-edge (2-flute) design balances feed rate capability with cut quality\u003c\/li\u003e\n\u003cli\u003eUncoated finish  -  no coating degradation risk in foam or soft-material applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, compatible with standard CNC and handheld router spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the ONSRUD 52-550 series.

Power down and lock out the spindle before changing tooling. Insert the shank fully into the collet to the manufacturer-recommended engagement depth before tightening. Verify spindle RPM and feed rate settings are appropriate for foam cutting before initiating a cut cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches (1-5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.375 inches (2-3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Foam\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\u003eHelix Angle\u003c\/strong\u003e: 25 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 52-550\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 52-560\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67912465711410,"sku":"52-560","price":125.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91cc7cec322cfc20cca77fedfbd8a404.jpg?v=1791234987","url":"https:\/\/voomisupply.com\/products\/onsrud-52-560-upcut-spiral-router-bit-3-16-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
