With a 0.5-inch cutter diameter and a 1.25-inch length of cut, it handles a wide range of profile and slotting operations where top-surface quality matters. The downcut flute geometry pushes chips downward, reducing tearout and fraying on the entry face of the workpiece. A 30-degree helix angle and double-edge (two-flute) configuration balance cutting efficiency with edge stability. The 0.5-inch shank fits standard half-inch router collets. This bit is installed and used by cabinetmakers, millwork shops, and CNC routing professionals.\u003c\/p\u003e\n\u003cp\u003eThe 57-362 is suited for CNC router and handheld router applications where surface quality on the top face is the priority. Typical use cases include cabinet door and panel routing, laminate work on solid-surface countertop materials, and production runs on MDF or plywood composites where tearout and fiber lifting are a persistent problem. The right-hand cutting direction is standard for conventional CNC spindle rotation. With a 2.25-inch shank length and 3.5-inch overall length, the bit seats securely in the collet while providing adequate reach for typical panel thicknesses.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDowncut flute geometry reduces tearout and fraying on the top face of the workpiece\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for wear resistance and edge retention in production routing\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances cutting efficiency with lateral stability\u003c\/li\u003e\n  \u003cli\u003eDouble-edge (two-flute) design suitable for natural wood, solid surfaces, and wood composites\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no coating buildup concerns when regrinding is required\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction matches standard CNC and handheld router spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the ONSRUD 57-200 series.

Power down and lock out the router or CNC spindle completely before changing tooling. Insert the shank fully into the collet and tighten to the router or collet manufacturer's specified torque using the appropriate collet wrench  -  do not over-tighten or leave the bit seated on the collet taper bottom. Confirm spindle RPM is appropriate for the cutter diameter and material before beginning the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.5 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: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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: Double 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: Natural Wood, Solid Surfaces, Wood Composites\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: 57-200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 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: 57-362\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67909971607858,"sku":"57-362","price":176.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b1fb4dbcaf9de9e4b6e3b5761d00457_78e199d8-271b-4537-9422-65fb5e70a68d.jpg?v=1791194286","url":"https:\/\/voomisupply.com\/products\/onsrud-57-362-downcut-spiral-router-bit-0-5-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
