Built from M42 high speed steel with a Titanium Nitride (TiN) coating, it delivers increased surface hardness and heat resistance compared to uncoated HSS tooling. The 0.375-inch diameter cutter has a 0.5625-inch length of cut, a 0.375-inch straight shank, and a 2.5-inch overall length. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation and smooth cutting action. Centercutting capability allows direct plunge entry without a pre-drilled pilot hole, adding versatility in milling setups.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits light to medium-duty milling on manual mills and CNC machining centers. It is well-suited for slotting, profiling, and shallow pocket operations on steel, aluminum, brass, and cast iron. The two-flute design provides larger chip gullets than higher-flute-count tools, making it a practical choice when chip clearance is the primary concern. It is typically used by machinists and tool-and-die professionals in job shop, maintenance, and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 high speed steel construction for toughness and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flute promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eTwo-flute configuration provides maximum chip clearance for slotting and softer materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with straight 0.375-inch shank for standard collet and end mill holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank end mill for use in ER collets, end mill holders, and similar 3\/8-inch bore toolholding systems on manual knee mills and CNC machining centers.

Ensure the spindle is fully stopped and locked before inserting or removing the end mill from the holder. Tighten the collet or set screw to the toolholder manufacturer's specification using the appropriate spanner wrench. Inspect the shank and cutting edges for chips or wear before each use, and confirm runout with a dial indicator when tight tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel, M42 grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5625 inches (9\/16 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 (2-1\/2 inches)\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\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\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E499921152\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730325307698,"sku":"E499921152","price":37.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2388c2d08f009c90cb7af5e89155a9e6_1fe36e3e-27b6-4eb2-a866-eafea3e777ae.jpg?v=1788715399","url":"https:\/\/voomisupply.com\/products\/hertel-e499921152-square-end-mill-3-8-inch-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
