It features a 0.125-inch cutter diameter, a 0.25-inch length of cut, and a 1\/8-inch shank diameter with a 1.25-inch shank length, yielding a 1.5-inch overall length. The downcut flute geometry directs chips downward, suppressing surface tearout on the top face of the workpiece. At 0.01 pounds, this is a lightweight precision tool designed for fine detail work in aluminum and similar non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThe 62-604 is suited for CNC routing operations on aluminum sheet and plate stock in both production and prototype environments. Its single-edge design reduces cutting forces, which is advantageous when machining thin or unsupported material. The 22-degree helix angle and right-hand cutting direction make it appropriate for conventional milling passes in aluminum. Typical users include CNC machinists, fabrication shops, and production routing operations working with non-ferrous metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDowncut flute geometry reduces surface tearout on the top face of the workpiece\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in aluminum applications\u003c\/li\u003e\n  \u003cli\u003eSingle-edge router style lowers cutting forces for thin or unsupported stock\u003c\/li\u003e\n  \u003cli\u003e22-degree helix angle optimized for right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suits aluminum and non-ferrous materials where coating adhesion is unnecessary\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch shank fits standard CNC collets without an adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the ONSRUD 62-600 series.

Power down and lock out the spindle before changing tooling. Seat the shank fully and evenly in the collet to the recommended engagement depth per the machine manufacturer's guidelines, and torque the collet nut to specification using the appropriate collet wrenches. Inspect the cutting edge for chips or wear before each use, as solid carbide is brittle and susceptible to damage from improper handling or interrupted cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 22 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Downcut\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\u003eMaterial Application\u003c\/strong\u003e: Aluminum\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: 62-600\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: 62-604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67908550132018,"sku":"62-604","price":79.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c22dcdc4ce0709f589f74bb5a8025e7a.jpg?v=1791183939","url":"https:\/\/voomisupply.com\/products\/onsrud-62-604-downcut-spiral-router-bit-0-125-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
