It carries an AlTiN coating and features a 37-degree helix angle with a variable index design that reduces harmonic vibration and improves surface finish. The 0.25-inch diameter pairs with a 0.375-inch length of cut and a 2.5-inch overall length, making it well-suited for slotting, profiling, and finishing passes in tight-tolerance applications. Built from micrograin carbide, this tool is installed by machinists and CNC operators working in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThe 38502 is designed for use across a broad spectrum of workpiece materials, including high-temperature alloys, stainless steels, cast irons, carbon and alloy steels, and titanium alloys, corresponding to material codes H, K, M, P, and S. Its right-hand cut and right-hand spiral flute geometry is standard for conventional CNC machining centers and manual mills. The straight cylindrical shank with an h6 tolerance provides a secure, concentric fit in standard collet or end mill holders. This is a regular-length tool appropriate for general-purpose milling operations where extended reach is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute variable index geometry reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides high heat resistance and extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction delivers rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting capable, allowing direct plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with h6 tolerance for precise, concentric tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for workpiece material codes H, K, M, P, and S, covering high-temperature alloys, cast irons, stainless steels, carbon and alloy steels, and titanium alloys.

Ensure the spindle is fully stopped and machine is powered down before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut to confirm concentricity within acceptable limits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Z5S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Workpiece Materials\u003c\/strong\u003e: H, K, M, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.064 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: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 38502\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51739838611762,"sku":"38502","price":74.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d64ebeb29f4d28ec26ef0262373b000_87d913a0-26ff-4552-b1de-ff9d7104a301.jpg?v=1788819431","url":"https:\/\/voomisupply.com\/products\/sgs-38502-square-end-mill-0-25-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
