With a 3\/64 inch (0.0469 inch) cutting diameter and a 9\/64 inch (0.1406 inch) length of cut, this tool is built for fine detail work where rigidity and edge retention matter. The TiAlN coating improves heat resistance and extends tool life in ferrous and high-temperature alloy applications. A 30-degree spiral helix with right-hand cut and right-hand flute geometry promotes efficient chip evacuation. Micrograin carbide substrate adds toughness and wear resistance at the cutting edge. Licensed machinists and CNC tooling technicians are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for small-part CNC milling, engraving, and precision slotting operations where a standard-size tool cannot reach or fit. The 1\/8 inch shank diameter makes it compatible with common collet systems found on vertical machining centers and benchtop CNC mills. The 1-1\/2 inch overall length keeps the tool compact and stiff, reducing deflection during light-to-moderate cuts in aluminum, steel, stainless steel, and similar materials. Its centercutting capability allows direct plunge entry without pre-drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/64 inch cutting diameter for fine-detail and small-geometry milling\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiAlN finish for improved heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e30-degree spiral flute with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003e1\/8 inch shank fits standard collet systems on CNC machining centers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for Series 402 square end mills with a 1\/8 inch shank diameter.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet to the minimum insertion depth required by the collet manufacturer to prevent pullout under cutting loads. Inspect the collet and collet nut for wear or contamination before tightening, as debris can cause runout that damages small-diameter end mills rapidly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/64 inch (0.0469 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/64 inch (0.1406 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 402\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 402-046911\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730526765362,"sku":"402-046911","price":30.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc3c9d98168a18aa69ae5bd65e125f2e.jpg?v=1788719009","url":"https:\/\/voomisupply.com\/products\/osg-402-046911-square-end-mill-3-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
