It features a 0.1875-inch (3\/16-inch) diameter with a 0.625-inch length of cut and a 2-inch overall length. The four-flute, right-hand helical design with a 40-degree high helix angle promotes efficient chip evacuation and smooth cutting action. An AlTiN (aluminum titanium nitride) PVD coating provides thermal resistance and hardness, extending tool life during high-speed or dry machining operations. The submicron carbide grade construction adds toughness and wear resistance across a wide range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, superalloys, and titanium. It handles both roughing and finishing operations in a single tool, making it practical for job shops and production environments where tool changes reduce throughput. The single-end, straight-cylindrical shank allows straightforward setup in standard collets or end mill holders. The standard-length configuration fits most vertical machining centers and CNC mill setups used in precision metalworking.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1875-inch mill diameter with tight tolerance of +0.0000 \/ -0.0020 inches for dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eFour right-hand helical flutes with 40-degree high helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for high-temperature resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade for improved toughness in ferrous and high-temp alloy cutting\u003c\/li\u003e\n\u003cli\u003eSuitable for both roughing and finishing passes\u003c\/li\u003e\n\u003cli\u003eSingle-end, straight-cylindrical shank with 0.1875-inch shank diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills with standard collet or end mill holder tooling that accepts a 3\/16-inch straight shank.

Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify collet size matches the 0.1875-inch shank diameter and that the tool is seated to the proper gauge length before tightening. Follow machine tool manufacturer guidelines for runout tolerances when setting up carbide end mills to avoid premature tool failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches\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\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0938 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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 157\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: PROMAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 157-01214\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51968521961778,"sku":"157-01214","price":74.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/978fdd8d8615fa0b951fcc5c784bcd73.jpg?v=1789951711","url":"https:\/\/voomisupply.com\/products\/promax-157-01214-ball-end-mill-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
