With a 0.25-inch cutter diameter, a 1.25-inch length of cut, and a 3-inch overall length, this bit is sized for precision profiling and edge-finishing work where controlled chip evacuation and surface quality matter. The downcut flute geometry drives chips toward the workpiece surface, reducing top-edge tearout and keeping parts securely seated during the cut. The 22-degree helix angle and right-hand cutting direction are optimized for clean entry and consistent tool engagement in aluminum stock.\u003c\/p\u003e\u003cp\u003eThis router bit is suited for CNC routing applications in fabrication shops, sign shops, and light manufacturing environments where aluminum sheet, plate, or extrusion work is common. The 0.25-inch shank fits standard 1\/4-inch collet systems, and the 1.75-inch shank length provides adequate grip depth in most CNC spindle setups. It is well-matched to single-pass profiling cuts, pocketing operations, and contour routing where a clean top surface finish is the primary requirement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDowncut flute geometry minimizes top-edge tearout on aluminum workpieces\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e22-degree helix angle supports smooth chip flow and consistent cut quality\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC router spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish maintains sharp edge geometry on aluminum without buildup risk\u003c\/li\u003e\n\u003cli\u003e1\/4-inch shank fits common collet sizes on CNC routers and handheld router tables\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC routers and routing equipment equipped with a standard 1\/4-inch collet.

Seat the shank to the full recommended collet depth and torque the collet nut to the router manufacturer's specification before operation. Inspect the bit for chips or edge damage before each use, as carbide tooling can fracture if run with existing micro-cracks. Follow all applicable shop safety standards for rotating tooling and workpiece fixturing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\u003eBit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRouter Style\u003c\/strong\u003e: Single Edge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Downcut\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: 22 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum\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: 62-600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: 62-624\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67918105182514,"sku":"62-624","price":138.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bba106575cc41cf3b1b97842a067bb9_0a18a046-af1e-4db4-8849-7491fa48cb66.jpg?v=1791267355","url":"https:\/\/voomisupply.com\/products\/onsrud-62-624-downcut-spiral-router-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
