It carries an APLUS PVD coating for improved wear resistance and heat management during aggressive cuts. The reduced-neck geometry extends reach while maintaining rigidity, making it well suited for profiling, contouring, and roughing passes in deep-pocket or tight-clearance setups. At 4 inches overall length with a 2.125-inch reach, it gives machinists access to features that standard-length tools cannot reach. A 5\/16-inch cutting diameter and 7\/16-inch length of cut keep chip loads predictable across a range of feed-and-speed conditions.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual milling operations where the workpiece material is steel, tool steel, stainless steel, or cast iron. The right-hand cut and right-hand spiral flute configuration suit standard spindle rotation. The reduced neck and stub-length-of-cut design make it a practical choice for die and mold work, aerospace component profiling, and general job-shop roughing where reach into narrow cavities is required. It is sold as a single-end tool, one piece per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAPLUS PVD coating rated for steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003eReduced-neck geometry provides 2.125-inch reach with 0.296-inch neck diameter for deep-feature access\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design supports efficient chip evacuation during roughing\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction with h6 shank tolerance for precise toolholder seating\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for standard CNC and manual mill compatibility\u003c\/li\u003e\n\u003cli\u003eMaximum TIR of 0.0005 inches for consistent runout performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC machining centers and manual mills with standard straight-cylindrical toolholders accepting a 5\/16-inch shank.

Secure the 5\/16-inch straight-cylindrical shank in a properly sized collet or end mill holder, ensuring full engagement depth per the toolholder manufacturer specification. Confirm spindle direction is set to right-hand rotation before engaging the cut. Inspect the toolholder bore and collet for runout before use to protect the h6 shank tolerance and maintain the 0.0005-inch maximum TIR rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 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: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.296 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.683 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: APLUS (PVD)\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 Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620 \/ -0.0620 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.143 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: HELICAL SOLUTIONS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 13167\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51739501035826,"sku":"13167","price":122.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bfb2cf25c9d7a6ff8ae7574c5a8075f2.jpg?v=1788815307","url":"https:\/\/voomisupply.com\/products\/helical-solutions-13167-ball-end-mill-5-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
