It carries a 21\/32-inch (0.6563 inches) cutting diameter with a 1-5\/8-inch (1.625 inches) length of cut and a 5\/8-inch shank diameter. The tool features a 30-degree helix angle, right-hand cut, right-hand spiral flute geometry, and an uncoated finish. Weighing 0.3 pounds, it is sized for general milling operations in machine shop and production environments. Machinists and CNC operators working with ferrous and non-ferrous materials install this tool in standard milling machines and machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill suits peripheral and slot milling applications in light to medium duty cutting scenarios. It is appropriate for use on milling machines, knee mills, and vertical machining centers in job shop and production settings. The 3-3\/4-inch overall length provides sufficient reach for most standard workholding setups. Note that this tool is not center-cutting, so it cannot be used for direct plunge entry without a pre-drilled hole or ramping entry strategy. The length of cut range for this tool falls within 1.5 to 2.0 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness and wear resistance in general machining applications\u003c\/li\u003e\n\u003cli\u003e21\/32-inch cutting diameter with 1-5\/8-inch length of cut\u003c\/li\u003e\n\u003cli\u003e4-flute, single-end design with 30-degree helix angle for balanced cutting action\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute configuration\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for a wide range of base materials\u003c\/li\u003e\n\u003cli\u003eNon-center-cutting geometry — ramp or pre-drill entry required for plunge operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 5\/8-inch collets, end mill holders, or Weldon-style side-lock holders on conventional and CNC milling machines accepting a 5\/8-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician following standard toolholding procedures. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully in the holder and torque the retention mechanism to the holder manufacturer specification. Confirm runout with a test indicator before production cutting, and verify the tool path does not require a plunge entry given this tool is not center-cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 21\/32 inch (0.6563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inch (1.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 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: 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\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\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\u003eLength of Cut Range\u003c\/strong\u003e: 1.5 to 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: E1031905\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747619832114,"sku":"E1031905","price":77.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/584f2728c6b975bf28d981d1dfad7417.jpg?v=1788883577","url":"https:\/\/voomisupply.com\/products\/hertel-e1031905-square-end-mill-21-32-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
