It features a 3\/8-inch diameter with a 1-3\/4-inch length of cut and a 4-inch overall length, placing it in the extra-long category for extended-reach work in deeper cavities and pockets. The four-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN (titanium carbonitride) coating increases surface hardness and wear resistance compared to uncoated carbide. Micrograin carbide construction supports tighter tolerances and longer tool life in ferrous and non-ferrous materials. This tool is sold as a single-end mill and is installed by machinists and CNC operators.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling slots, profiles, and pockets in a wide range of materials including steel, stainless steel, cast iron, and aluminum alloys. The extra-long length of cut makes it appropriate for deep-pocket milling and side-wall finishing operations where standard-length tools cannot reach. The right-hand cutting direction and right-hand flute configuration are compatible with conventional CNC machining centers and manual knee mills. Centercutting capability allows direct plunge entry without pre-drilling. It is appropriate for both production environments and job shop use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for extended tool life and tight dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves hardness and reduces wear in abrasive and ferrous materials\u003c\/li\u003e\n  \u003cli\u003eFour flutes with 30-degree helix angle for efficient chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eExtra-long 1-3\/4-inch length of cut enables deep-pocket and extended-reach milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and flute direction compatible with standard CNC and manual milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8-inch collet chucks, end mill holders, and shrink-fit tooling systems on CNC machining centers and manual milling machines.

Ensure the spindle is fully stopped and the machine is placed in an energy-isolated state before changing tooling. Verify tool holder cleanliness and proper seating depth before tightening to prevent runout. Do not exceed the recommended depth-of-cut or feed rate parameters for the workpiece material and machine horsepower.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\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: 1-3\/4 inches (1.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000\/-0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 750435\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737183355186,"sku":"750435","price":93.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e2e4d263e8589495b673a9ae4ad8244.jpg?v=1788785323","url":"https:\/\/voomisupply.com\/products\/hertel-750435-square-end-mill-3-8-in-4-flute-solid-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
