It features a 1\/4 inch cutting diameter, a 3\/4 inch length of cut, and a corner radius range of 0.04 to 0.05 inches. The four-flute geometry combined with a 40-degree high helix angle promotes efficient chip evacuation and smooth surface finishes. A TiCN coating increases surface hardness and wear resistance, extending tool life in demanding cutting conditions. The centercutting design allows plunge milling as well as standard peripheral and slot cutting. This tool is intended for use by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish and semi-finish milling of ferrous and non-ferrous metals, alloy steels, and hardened materials where corner edge protection and tight tolerances are required. The fine-pitch flute spacing and right-hand cutting and flute direction make it a standard fit for conventional CNC machining centers and manual knee mills. The 2-1\/2 inch overall length and 1\/4 inch shank diameter are compatible with standard collet toolholding systems. It is well suited for die and mold work, contour milling, and applications requiring a controlled edge radius rather than a sharp corner.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases hardness and reduces tool wear in abrasive cutting conditions\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.04 to 0.05 inches protects the cutting edge and improves part surface quality\u003c\/li\u003e\n  \u003cli\u003e40-degree high helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute, fine-pitch geometry for controlled chip load per tooth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/4 inch collet or end mill holders on CNC machining centers and manual milling machines.

Secure the 1\/4 inch shank in a properly sized collet or toolholder and torque the retention nut per the toolholder manufacturer specification. Verify runout at the cutting edge before engaging the workpiece. Follow all applicable shop safety procedures and machine tool manufacturer guidelines when setting speeds and feeds.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.04 to 0.05 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\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\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 101\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: PROMAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 101-01612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51972979917106,"sku":"101-01612","price":118.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1ae3ca868f30d669c52e84bedee90c9.jpg?v=1789971468","url":"https:\/\/voomisupply.com\/products\/promax-101-01612-corner-radius-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
