Built to Series 14 specifications, it features a 0.25-inch cutting diameter, a 0.5-inch length of cut, and a 0.25-inch straight-cylindrical shank with a 2.5-inch overall length. The micrograin carbide substrate provides hardness and edge retention suited for high-speed cutting operations. A titanium carbonitride (TiCN) coating reduces friction and improves wear resistance. The 4-flute, spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. Centercutting capability allows direct plunge entry into workpiece material without a pre-drilled pilot hole.\u003c\/p\u003e\u003cp\u003eThe SGS 39629 is suited for milling ferrous and non-ferrous metals as well as high-temperature alloys and cast materials, corresponding to primary workpiece material codes H, K, M, N, P, and S. The stub-length geometry makes it appropriate for applications requiring rigidity and reduced deflection in tight setups. This end mill is typically installed by machinists and CNC operators in production shops, tool rooms, and job shops running vertical or horizontal machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and long tool life\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and improves wear resistance at the cutting edge\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for standard spindle compatibility\u003c\/li\u003e\n\u003cli\u003eStub length reduces deflection in rigid, close-tolerance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series 14 OEM-style solid carbide square end mill compatible with standard 0.25-inch straight-cylindrical shank toolholders on CNC machining centers and manual mills.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a calibrated torque-rated toolholder and verify runout with a dial indicator before starting a cut. Consult the machine manufacturer and applicable shop safety procedures when setting feeds, speeds, and depth of cut for the target workpiece material.\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: 0.5 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: 4\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: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 39629\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51732884947250,"sku":"39629","price":75.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f8f6268eafed79c216f8064fe5b8bca.jpg?v=1788748047","url":"https:\/\/voomisupply.com\/products\/sgs-39629-square-end-mill-0-25-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
