It carries a 29\/64 inch (0.4531 inch) cutting diameter with a 1 inch length of cut and a 1\/2 inch shank diameter, yielding a 4-1\/8 inch overall length. The spiral flute geometry runs at a 30-degree helix angle with right-hand cut and right-hand flute orientation. Uncoated and designed for regular-length applications, this tool is suited to milling operations where HSS tooling is preferred over carbide. Machinists and tool-room operators working on manual mills, knee mills, or CNC machines running softer workpiece materials will find this a practical, workhorse end mill.\u003c\/p\u003e\u003cp\u003eThis end mill fits into general-purpose milling work across job shops, maintenance departments, and production environments. Its double-end configuration extends tool life by offering a second cutting end once the first is worn. The 30-degree helix promotes good chip evacuation and smooth cutting action on steel, aluminum, and similar materials. With a 1\/2 inch shank, it seats in standard ER, Weldon, or collet-style toolholders commonly found on bridgeport-style and CNC vertical mills. It is not center-cutting, so it is not suited for direct plunge operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design provides two usable cutting ends, extending service life\u003c\/li\u003e\n\u003cli\u003eM7 high speed steel construction offers toughness and wear resistance in conventional milling\u003c\/li\u003e\n\u003cli\u003e30-degree spiral helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration — standard orientation for most milling setups\u003c\/li\u003e\n\u003cli\u003eUncoated finish — compatible with re-sharpening and regrind services\u003c\/li\u003e\n\u003cli\u003eNot center-cutting — best suited for peripheral and slot milling with pre-drilled entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/2 inch shank square end mill suitable for use in any toolholder accepting a 1\/2 inch straight shank, including ER collet chucks, Weldon-style holders, and end mill adapters on vertical milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended engagement depth in the toolholder and torque the set screw or collet nut per the toolholder manufacturer specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on HSS tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 29\/64 inch (0.4531 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eCenter Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: E1051029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737991053618,"sku":"E1051029","price":71.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e09bbed8fd5465b7f8ad48eeb8b9702.jpg?v=1788795501","url":"https:\/\/voomisupply.com\/products\/hertel-e1051029-square-end-mill-29-64-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
