Built from M42 cobalt high-speed steel, this two-flute, single-end tool delivers reliable cutting performance in a compact geometry. It features a 30-degree helix spiral flute configuration with right-hand cut and right-hand flute orientation. The centercutting design allows plunge entry directly into the workpiece. At 0.3438 inches in cutting diameter with a 1-inch length of cut, it is sized for slot milling, profiling, and light pocketing on manual mills and CNC machining centers. Machinists and tool-and-die professionals are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for general-purpose and production milling in job shops, maintenance environments, and manufacturing facilities. The 3\/8-inch shank diameter is a common standard for both R8 collets and ER-style toolholding systems found on knee mills and vertical machining centers. The uncoated finish makes it appropriate for use with cutting fluids on a range of workpiece materials. The 2-3\/4-inch overall length provides clearance in typical fixture setups without excessive overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for heat and wear resistance in tough materials\u003c\/li\u003e\n\u003cli\u003e30-degree helix spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation, standard for conventional and climb milling\u003c\/li\u003e\n\u003cli\u003eUncoated finish compatible with cutting fluid lubrication strategies\u003c\/li\u003e\n\u003cli\u003eTwo-flute design provides larger chip clearance for slot milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 3\/8-inch collet toolholding systems on vertical knee mills and CNC machining centers.

Power down and lock out the spindle before inserting or removing the end mill from the collet or toolholder. Ensure the shank is fully seated to the recommended engagement depth and that the collet nut is torqued according to the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use, and verify spindle speed and feed rate against published cobalt HSS cutting data for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/32 inch (0.3438 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: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (0.3438 decimal reference: 1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 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\u003eCoating\u003c\/strong\u003e: Uncoated\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: 0.504 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: E299914092\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728709288242,"sku":"E299914092","price":37.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9113432d8ce403ab10992ff139c10caa.jpg?v=1788695331","url":"https:\/\/voomisupply.com\/products\/hertel-e299914092-square-end-mill-11-32-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
