With a 1\/4 inch cutting diameter and a 1-3\/4 inch length of cut, this tool handles slotting, profiling, and peripheral milling in a wide range of ferrous and non-ferrous materials. The 4-flute geometry provides a balance of chip evacuation and surface finish quality. An AlTiN (aluminum titanium nitride) coating improves hardness and heat resistance at the cutting edge, extending tool life in demanding high-speed and dry machining environments. The 30-degree helix angle promotes smooth cutting action and reduces cutting forces during operation.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills used in job shops, tool rooms, and production environments. It is a single-end tool with a right-hand cut and right-hand flute direction. The 1\/4 inch shank diameter fits standard ER collets, end mill holders, and hydraulic chucks commonly found in these setups. It is appropriate for machinists and tooling specialists working in aerospace, mold and die, medical, and general precision manufacturing where tight tolerances and consistent tool life are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life in high-speed machining\u003c\/li\u003e\n\u003cli\u003e4-flute design balances chip removal with surface finish quality\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle reduces cutting forces and improves chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with a 4 inch overall length for reach in typical setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 1\/4 inch end mill holders, ER collet chucks, and hydraulic tool holders on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the spindle before changing tooling. Ensure the shank is fully seated and properly torqued in the tool holder per the holder manufacturer's specifications. Inspect the cutting edges and coating for chips or wear before each use, and follow machine manufacturer guidelines for feed rates and speeds appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 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\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\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 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\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.25 inches length, 0.51 inches width, 0.51 inches height\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 898016-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51734072394034,"sku":"898016-C3","price":87.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d70c12256c804cf5e3a34b4b274a50d_4794d9fe-d95a-4f3f-aa91-a8e7dbb09c92.jpg?v=1788760759","url":"https:\/\/voomisupply.com\/products\/harvey-tool-898016-c3-square-end-mill-1-4-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
