This single-end tool features three flutes in a right-hand cutting and right-hand flute direction configuration, providing efficient chip evacuation and smooth cutting performance. Built from K600-grade solid carbide, it delivers the hardness and wear resistance required for demanding cutting tasks. The 3\/16 inch (0.1875 inch) shank diameter makes it suited for smaller-diameter work where tight tolerances and controlled material removal are critical. It is center-cutting capable, allowing plunge cuts in addition to peripheral and slot milling. Machinists and tool-and-die professionals are the primary users of this end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for use in vertical machining centers, CNC mills, and manual knee mills where a 3\/16 inch shank can be properly chucked. Its solid carbide construction and fixed helix design make it a reliable choice for ferrous and non-ferrous materials in precision shop environments. The single-end geometry keeps the tool straightforward to set up and qualify in a tool holder. It is not an extended-reach tool, so it is best applied in standard-depth cutting scenarios where tool overhang is minimized.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eK600-grade solid carbide construction for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eThree flutes for balanced chip load and efficient material removal\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable — supports plunge entry cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003eSingle-end design for straightforward tool qualification and holder setup\u003c\/li\u003e\n  \u003cli\u003eFixed helix and fixed index geometry for consistent, predictable cutting behavior\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 3\/16 inch collets or end mill holders on CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Secure the 3\/16 inch shank fully in a properly sized collet or end mill holder, ensuring minimum runout before tightening. Confirm spindle direction is set to right-hand rotation before engaging the cut. Inspect the cutting edges for chips or wear before each use, as carbide tooling is brittle and should not be used if damage is present.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: K600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3870450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733707424050,"sku":"3870450","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50afcd3c9ef7f9f7abcbaa8b7442d485_b48d2ff3-ab80-4835-9458-32d5351043a4.jpg?v=1788758595","url":"https:\/\/voomisupply.com\/products\/kennametal-3870450-square-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
