Part of the HPBNDM series, it features a 0.1875-inch mill diameter with a matching 0.1875-inch length of cut, a 0.25-inch straight cylindrical shank, and a 3.0-inch overall length. The extended-reach geometry and low 15-degree helix angle make it well suited for deep-pocket finishing where rigidity and controlled chip evacuation matter. A TiAlN PVD coating provides thermal resistance and wear protection in high-hardness cutting environments. Installation and use require a CNC machining center operator or skilled manual mill operator familiar with carbide tooling handling procedures.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for finishing cuts in ferrous materials, particularly hardened steels. The center-cutting design supports plunging and ramping entry without a pre-drilled pilot hole. The 0.0938-inch nose radius, 0.7141-inch neck length, and 0.9016-inch reach length allow access to confined features and deep wall profiles common in die and mold work, aerospace components, and precision machined parts requiring tight tolerances in hard material stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction, material grade C2, for rigidity in hard-material cuts\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating rated for machining hardened materials above 60 HRC\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry supports plunging and ramping operations\u003c\/li\u003e\n  \u003cli\u003eExtended-reach design with 0.9016-inch reach length for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand cut, right-hand spiral configuration for finishing passes\u003c\/li\u003e\n  \u003cli\u003eLow 15-degree helix angle reduces lateral cutting forces in hard steels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for machining steel and hardened materials with a hardness greater than 60 HRC.

Ensure the machine spindle is fully stopped and the tool changer or spindle is de-energized before mounting or removing the end mill. Use a calibrated collet or precision end mill holder to stay within the shank diameter tolerance of +0.0000\/-0.0031 inches. Solid carbide tooling is brittle — avoid impact loading, side pressure during clamping, or dropping the tool on hard surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.7141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.9016 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\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Hardened Materials\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0000\/-0.0031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HPBNDM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 1925140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728697491762,"sku":"1925140","price":141.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53e019b6772a221a2a70503f67f66a74.jpg?v=1788695203","url":"https:\/\/voomisupply.com\/products\/kennametal-1925140-ball-end-mill-0-1875-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
