Built from solid carbide with a micrograin grade substrate, it delivers the hardness and wear resistance needed for high-feed roughing passes. The 3\/8-inch diameter cutter features four flutes with a right-hand cutting and right-hand flute direction. A TiCN coating reduces friction and extends tool life in ferrous and non-ferrous applications. The stub-length configuration keeps the tool rigid under heavy chip loads, minimizing deflection. This end mill is a tool used by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 2500156 is suited for roughing operations on machining centers and manual mills where rapid stock removal is the priority. The centercutting geometry allows plunge entry, giving the operator flexibility in toolpath strategy. With a 1\/2-inch length of cut and a 3\/8-inch shank, this is a compact, stub-reach tool intended for shallow-to-moderate depth cuts in steel, stainless, aluminum, and similar workpiece materials. It is a practical choice for shops needing a reliable rougher in a common diameter without switching to a larger shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for hardness and edge retention under roughing loads\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces heat buildup and extends tool life in ferrous applications\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eFour-flute right-hand configuration for efficient chip evacuation at higher feed rates\u003c\/li\u003e\n  \u003cli\u003eStub-length build maximizes rigidity and minimizes deflection during heavy cuts\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank with tight diameter tolerance of plus 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide roughing end mill suitable for use in standard 3\/8-inch collets and end mill holders on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists using an appropriate end mill holder or collet chuck sized for a 3\/8-inch shank. Ensure the machine spindle is fully stopped and locked before changing tooling. Verify runout with a dial indicator after seating the tool in the holder to confirm concentricity within acceptable limits. Follow the machine manufacturer and shop safety guidelines for speeds, feeds, and chip clearance when setting up a roughing operation.\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 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inches (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to minus 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.000 to minus 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eLength Type\u003c\/strong\u003e: Stub\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2500156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753158836530,"sku":"2500156","price":79.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92701f297d2228fc0a52975ff81355f8.jpg?v=1788933364","url":"https:\/\/voomisupply.com\/products\/accupro-2500156-roughing-end-mill-3-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
