It measures 0.0938 inches in diameter with a 0.375-inch length of cut, a 0.125-inch shank diameter, and a 1.75-inch overall length. The cutter features four spiral flutes with a 30-degree helix angle and a diamond coating applied over a micrograin carbide substrate. This combination supports efficient chip evacuation and edge retention at small diameters. It is a single-end, right-hand cut tool intended for use by machinists and CNC operators working with tight-tolerance features.\u003c\/p\u003e\n\u003cp\u003eThe OSG 70400516 belongs to OSG Series 7040 and is suited for milling slots, pockets, and contours in a range of workpiece materials where a small-diameter, high-rigidity tool is required. The 0.0938-inch cutting diameter makes it appropriate for fine detail work and narrow slot milling. The centercutting geometry allows plunge entry, adding flexibility in CNC machining center applications. Regular-length designation keeps the tool compact for stability at depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0938 inches (3\/32 inch) cutting diameter for fine-detail and narrow-slot applications\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention at small diameters\u003c\/li\u003e\n  \u003cli\u003eDiamond coating for enhanced wear resistance and surface finish performance\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes at 30-degree helix angle for effective chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration; single-end design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production cutting tool for CNC machining centers and manual mills accepting a 0.125-inch (1\/8 inch) straight shank.

Secure the 0.125-inch shank in a properly sized collet or end mill holder and verify runout before cutting. Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing tooling. Do not exceed the tool manufacturer's recommended speeds and feeds for the cutting diameter and workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0938 inches (3\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches (1-3\/4 inch)\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 7040\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 70400516\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728549314866,"sku":"70400516","price":172.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38155955685ae3a61521e2cc58728d33.jpg?v=1788693172","url":"https:\/\/voomisupply.com\/products\/osg-70400516-square-end-mill-0-0938-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
