It features a 0.1969-inch cutting diameter with a 0.9843-inch length of cut, making it suited for deep slot milling and extended-reach applications. The four-flute, spiral configuration runs a 30-degree helix angle, promoting efficient chip evacuation and smooth cutting action. A titanium nitride (TiN) coating increases surface hardness and extends tool life in abrasive materials. Micrograin carbide construction provides rigidity and resistance to deflection at this small diameter. Licensed machinists and CNC operators are the primary installers of this tooling.\u003c\/p\u003e\u003cp\u003eThe SGS 49391 belongs to the Series 1XLM extra-long end mill family and is intended for milling ferrous and non-ferrous metals across a broad range of workpiece material categories. Primary workpiece material codes include H, K, M, N, P, and S, covering hardened steels, cast iron, stainless steel, non-ferrous alloys, carbon steels, and high-temperature alloys. Its extra-long length type makes it well suited for deep cavity milling, contour work, and situations where standard-length end mills cannot reach the required depth. The straight-cylindrical shank fits standard ER and side-lock collet systems common to vertical machining centers and CNC routers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1969-inch (5 mm) cutting diameter with matching 0.1969-inch straight-cylindrical shank\u003c\/li\u003e\n\u003cli\u003e0.9843-inch (25 mm) length of cut in the extra-long Series 1XLM configuration\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes at 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating for increased surface hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and minimal deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute direction; center-cutting capable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with workpiece material codes H, K, M, N, P, and S as designated in the SGS Series 1XLM product line.

Always power down and lock out the spindle before changing tooling. Verify collet size matches the 0.1969-inch shank diameter and confirm runout with a dial indicator before cutting. Follow machine manufacturer torque specifications for collet nuts and observe recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1969 inches (5 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.9843 inches (25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1969 inches (5 mm)\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: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.050 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.008 mm\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: 1XLM\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\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: 49391\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51755307106610,"sku":"49391","price":74.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf4ea3103de48270d5c4ad3e33fec59f_a5e22b8b-003f-4d43-9ddf-5998ef8a8753.jpg?v=1788953416","url":"https:\/\/voomisupply.com\/products\/sgs-49391-square-end-mill-0-1969-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
