With a 0.125-inch cutter diameter and a 0.5-inch length of cut, this bit is built for tight-tolerance routing passes where clean chip evacuation matters. The upcut flute geometry pulls chips up and away from the workpiece, reducing heat buildup at the cutting edge. A 30-degree helix angle and double-edge construction deliver smooth, consistent cuts. At 2 inches overall length with a 1\/4-inch shank, it mounts securely in standard collet-style router chucks used on CNC routers and handheld trim routers alike.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for residential shop work, production CNC routing, and light industrial fabrication. It performs well in natural wood, MDF, phenolic, acrylic, and similar solid-surface materials. The small 0.125-inch diameter makes it particularly effective for fine detail work, narrow slots, and profile passes where a larger bit cannot reach. It is a right-hand cutting tool and is intended for use without a pilot bearing, making it a programmer- or operator-guided application in CNC and template routing setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for wear resistance and edge retention in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eUpcut flute geometry clears chips away from the cut zone, reducing recutting and heat\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle for smooth shear cutting action\u003c\/li\u003e\n  \u003cli\u003eDouble-edge design for balanced cutting load and improved finish quality\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch shank diameter fits standard CNC and handheld router collets\u003c\/li\u003e\n  \u003cli\u003eUncoated carbide  -  compatible with re-sharpening services\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in natural wood, plastics, solid surfaces, and wood composites. Part of the ONSRUD 52-200 series.

Before changing bits, power down the router and allow the spindle to come to a complete stop. Insert the shank fully into the collet to the manufacturer-recommended engagement depth and tighten per the router or spindle manufacturer's torque procedure. At 0.125-inch diameter, feed rate and spindle RPM must be carefully programmed to avoid deflection or breakage  -  consult the ONSRUD speeds and feeds chart for the 52-200 series before first use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches (1\/2 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: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 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\u003eHelix Angle\u003c\/strong\u003e: 30 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\u003eMaterial Application\u003c\/strong\u003e: Natural Wood, Plastics, Solid Surfaces, Wood Composites\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 52-200\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: 52-240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67912290369842,"sku":"52-240","price":63.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d14b20d81e001aae46b51e58af4a5a1b.jpg?v=1791231965","url":"https:\/\/voomisupply.com\/products\/onsrud-52-240-upcut-spiral-router-bit-1-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
