Built from micrograin solid carbide, it delivers rigidity and wear resistance required for demanding cuts. The tool features a 1 inch cutting diameter, a 1.5 inch length of cut, and a 4 inch overall length with a 1 inch shank diameter. With 3 spiral flutes ground at a 30-degree helix angle and a right-hand cut with right-hand flute direction, it supports efficient chip evacuation and smooth surface finishes. The centercutting geometry allows plunge entry, expanding its range of usable operations.\u003c\/p\u003e\u003cp\u003eThe OSG 403-1000 is suited for milling slots, pockets, profiles, and contours in ferrous and non-ferrous materials. It is appropriate for use on vertical machining centers and manual knee mills where a regular-length, uncoated solid carbide end mill is specified. The tool belongs to the OSG Series 403 line and is sized for heavy stock removal or finish passes requiring a full 1 inch diameter cut. It is typically specified by machinists and CNC operators working in job shops, tool rooms, or production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003e3 spiral flutes at 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids on a wide range of materials\u003c\/li\u003e\n\u003cli\u003eRegular length geometry provides stiffness and reduces deflection at 1 inch diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style tooling solution for machining centers and manual mills accepting a 1 inch straight shank end mill in the OSG Series 403 configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of end mills should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a proper collet or end mill holder rated for a 1 inch shank diameter and torque the retention hardware to the machine manufacturer specification. Verify runout with a dial indicator before beginning a cut to confirm proper seating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 403\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 403-1000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731376308530,"sku":"403-1000","price":345.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57f9bca003f34acfe7d0fcae3eb0833c.jpg?v=1788730177","url":"https:\/\/voomisupply.com\/products\/osg-403-1000-square-end-mill-1-inch-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
