Built on OSG's HP460 series platform, it features a 60-degree helix angle and TiAlN coating, making it well suited for aggressive cuts in steel, stainless steel, cast iron, high-temp alloys, and hardened materials. The micrograin carbide substrate supports rigidity and edge retention at elevated cutting speeds. At 0.375 inches in diameter with a 0.75-inch length of cut and 2.5-inch overall length, this is a compact, right-hand cut tool intended for CNC machining centers and manual mills used by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is used in precision metal cutting applications across job shops, aerospace component manufacturing, die and mold work, and general machining of ferrous and high-temperature alloy workpieces. The single-end, three-flute configuration balances chip evacuation with cutting edge strength, giving it an advantage in slotting and pocketing operations in difficult-to-machine materials. The centercutting geometry allows plunge entry, expanding its utility in multi-axis and contouring setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e60-degree helix angle for aggressive chip flow and reduced cutting forces in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in high-heat cutting environments including hardened steels and high-temp alloys\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction provides edge stability and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eThree-flute geometry balances chip clearance and core strength in slotting and profiling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute spiral — standard orientation for conventional CNC setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with steel, stainless steel, cast iron, high-temp alloys, and hardened materials as stated by the manufacturer.

Ensure the machine spindle and tool holder are clean and within spec before seating the shank to the correct insertion depth. Follow your machine tool manufacturer's recommendations for runout tolerance and torque when securing set-screw or collet-style holders. Always verify feed rates, speeds, and depth-of-cut parameters against OSG HP460 series cutting data before beginning a new material or operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 60 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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy, Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP460\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: HP460-3750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730322096434,"sku":"HP460-3750","price":94.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e22aa87f58832e6286a768e3ddaf69f2.jpg?v=1788715347","url":"https:\/\/voomisupply.com\/products\/osg-hp460-3750-square-end-mill-3-8-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
