Ground from high speed steel (HSS) stock, it carries a titanium nitride (TiN) coating that extends tool life by reducing friction and increasing surface hardness at the cutting edge. The mill measures 0.5 inches in diameter with a 1-inch length of cut (LOC) and a 3.25-inch overall length (OAL). A 30-degree spiral helix angle promotes efficient chip evacuation and reduces cutting forces, making it suitable for slotting, profiling, and light pocket-milling operations. Machinists and tool-and-die professionals are the primary installers and operators.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for manual knee mills, CNC machining centers, and bridgeport-style equipment where a 0.5-inch shank diameter collet or end mill holder is available. The centercutting geometry allows plunge entry into the workpiece without a pre-drilled hole, adding versatility in die and mold work. Right-hand cut with right-hand flute direction is standard orientation for conventional and climb-milling passes on typical shop equipment. It fits production and maintenance machining environments in both job-shop and industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness in interrupted cuts and on manual machines\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow in slotting and profiling operations\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a starter hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction match standard spindle rotation on most mills\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with a square corner profile for flat-bottom features and sharp shoulders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any machine tool accepting a 0.5-inch shank diameter through a collet, end mill holder, or Weldon-style chuck.

Power down and lock out the spindle before changing tooling. Seat the shank fully into the collet or holder and tighten to the tool holder manufacturer's specified procedure before starting the spindle. Inspect the TiN coating and cutting edges for chips or wear before each use; a damaged edge should be reground or replaced rather than run to avoid workpiece damage or tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eEnd Type\u003c\/strong\u003e: Single End, Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: E899921292\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737139020082,"sku":"E899921292","price":52.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2388c2d08f009c90cb7af5e89155a9e6_b4c6f25c-25ad-453f-9fd3-9603ee7d8dda.jpg?v=1788784836","url":"https:\/\/voomisupply.com\/products\/hertel-e899921292-square-end-mill-1-2-in-2-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
