With a 0.25-inch cutter diameter and a 0.75-inch length of cut, it delivers precise material removal in CNC routing and handheld router applications. The downcut flute geometry drives chips downward, which minimizes surface tearout and keeps the top face of the workpiece clean. At 2.5 inches overall length with a 0.25-inch shank, this single-edge bit fits standard router collets and suits shops running tight-tolerance aluminum plate or sheet work.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for CNC machining centers and routing fixtures processing aluminum sheet, plate, and extrusions. The right-hand cutting direction and 22-degree helix angle are optimized for clean edge quality in aluminum. The single-edge design reduces cutting forces, which is an advantage in light-duty fixturing or thin-wall aluminum profiles. It is typically installed and operated by machining professionals, CNC programmers, and tooling technicians in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDowncut flute geometry drives chips downward, reducing surface tearout on the top face\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in aluminum applications\u003c\/li\u003e\n  \u003cli\u003eSingle-edge design lowers cutting forces for improved performance in light fixturing setups\u003c\/li\u003e\n  \u003cli\u003e22-degree helix angle optimized for clean cuts in aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains sharp edge geometry without coating buildup on aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC routers and handheld routers equipped with a 1\/4-inch collet.

Power down and lock out the spindle before changing tooling. Insert the shank fully into the collet to the recommended engagement depth and torque the collet nut to the router or spindle manufacturer's specification. Verify runout with a dial indicator before beginning a production run, and confirm feed rate and spindle speed settings are appropriate for the material and cut depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.75 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: 0.05 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: 62-622\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67906060353842,"sku":"62-622","price":99.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bba106575cc41cf3b1b97842a067bb9.jpg?v=1791163813","url":"https:\/\/voomisupply.com\/products\/onsrud-62-622-downcut-spiral-router-bit-1-4-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
