At 1\/4 inch in diameter with a 1\/2 inch length of cut and a 30-degree helix angle, this centercutting tool handles slotting, side milling, and plunge operations. The TiCN (Titanium Carbonitride) coating adds surface hardness and lubricity, extending tool life in abrasive cutting environments. Micrograin carbide construction gives this stub-length end mill the rigidity needed for demanding shop-floor applications. The 1\/4 inch shank and 2 inch overall length make it compatible with standard collet chucks and milling holders.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual milling machines in job shops, tool rooms, and production environments. The 4-flute configuration balances material removal rate with chip evacuation, making it appropriate for finishing and light-to-moderate roughing passes in steel, stainless, cast iron, and similar materials. The right-hand cut and right-hand spiral flutes are the standard configuration for conventional milling setups. Its stub length improves rigidity in setups where deflection and chatter are concerns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating improves wear resistance and surface hardness for longer tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction provides rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting forces across the flute length\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry suited for finishing passes and moderate stock removal\u003c\/li\u003e\n\u003cli\u003eStub length reduces overhang and minimizes deflection in tight setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4 inch shank square end mill compatible with collet chucks, end mill holders, and shrink-fit tooling systems used on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in a safe state before changing tooling. Secure the shank to the full recommended grip depth in the holder and verify runout before beginning a cut. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches (1\/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: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN (Titanium Carbonitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 inches (1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.5000 - 0.6000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0000 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\u003eLength Type\u003c\/strong\u003e: Stub\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: 0.05 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: 750371\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727390769458,"sku":"750371","price":36.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22ff5571b5af5ffa9366959c5c1f3dac.jpg?v=1788677221","url":"https:\/\/voomisupply.com\/products\/hertel-750371-square-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
