With a 3\/8 inch cutting diameter, a 7\/8 inch length of cut, and a 5-flute geometry paired with a 45-degree helix angle, this tool delivers efficient chip evacuation and smooth surface finishes at higher feed rates. The micrograin carbide substrate provides wear resistance and edge retention suited to demanding production environments. It is a single-end, right-hand cut, right-hand flute tool with a centercutting capability, allowing it to plunge directly into workpiece material. Machinists and CNC operators in job shops, tool rooms, and production facilities are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe 455-3752 is well suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials where an uncoated carbide tool is appropriate. The 3\/8 inch shank diameter matches the 3\/8 inch cutting diameter for direct chuck or collet mounting without a reducer. The 2-1\/2 inch overall length keeps overhang manageable for rigidity in tight-clearance setups. Its spiral flute design and 45-degree helix angle make it a practical choice for applications requiring smooth chip flow and reduced cutting forces, including finishing passes on steel, aluminum, and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-flute design with 45-degree helix angle for improved chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for edge retention and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for standard CNC and manual mill spindle rotation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for applications where coating is not required or where re-sharpening is anticipated\u003c\/li\u003e\n  \u003cli\u003eMatched shank and cutting diameter at 3\/8 inch for straightforward collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the OSG Series 455C line of solid carbide square end mills.

Seat the shank fully into the collet or holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut to avoid premature edge wear. Extended reach or long-overhang setups are not recommended for this tool given its standard 2-1\/2 inch overall length.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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\u003eSeries\u003c\/strong\u003e: 455C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: 455-3752\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733127561522,"sku":"455-3752","price":57.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bfab475d49bc34527f0c245116b7895_fad5f52d-4b24-4072-8750-88342ddf4597.jpg?v=1788751592","url":"https:\/\/voomisupply.com\/products\/osg-455-3752-square-end-mill-3-8-inch-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
