With a 1\/8 inch cutting diameter and a 3\/4 inch length of cut, it is built for slotting, profiling, and finishing passes in tight workspaces. The micrograin carbide substrate delivers hardness and wear resistance, while the AlTiN coating extends tool life in high-temperature cutting conditions. A 30-degree helix angle promotes chip evacuation and reduces cutting forces. The variable index geometry helps suppress chatter, making this mill well-suited for fine-finish operations in difficult materials.\u003c\/p\u003e\n\u003cp\u003eThe SGS 31790 is intended for use in CNC machining centers and high-speed milling applications. Its primary workpiece material codes cover hardened steels (H), cast iron (K), stainless steel (M), non-ferrous metals (N), steel (P), and high-temperature alloys (S). The long-series 1LB designation provides extended reach for deep-pocket and complex-contour work. Single-end configuration and right-hand cut and flute direction are standard for conventional CNC toolpath programming. This tool is typically installed and operated by machinists and CNC programmers in precision job shops and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/8 inch cutting diameter with a 3\/4 inch length of cut for precision milling in tight areas\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration supports higher feed rates and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides oxidation resistance and extended tool life in high-temperature applications\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle aids chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eVariable index geometry reduces chatter for consistent surface quality\u003c\/li\u003e\n  \u003cli\u003eLong-series 1LB design enables extended-reach and deep-pocket machining\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC milling machines accepting a 1\/8 inch shank.

Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Secure the 1\/8 inch shank in a compatible collet or end mill holder torqued to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production run, as micrograin carbide tools are sensitive to excessive runout at small diameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\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\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1LB\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 \/ -0.00032 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31790\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51753387032882,"sku":"31790","price":49.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0738be92b848acbbe8fc4cacdaa1cfa.jpg?v=1788936133","url":"https:\/\/voomisupply.com\/products\/sgs-31790-ball-end-mill-1-8-in-4-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
