Built from micrograin solid carbide with an AlTiN finish, it delivers high heat resistance and extended tool life in ferrous and non-ferrous materials. The 1\/8 inch diameter cutting head features a 1\/2 inch length of cut, a 1-1\/2 inch overall length, and a 1\/8 inch straight-cylindrical shank. A 30-degree helix angle combined with a variable index geometry promotes chip evacuation and reduces chatter at the cutting edge. This tool is installed by machinists and CNC operators in shop environments.\u003c\/p\u003e\u003cp\u003eThe 30198 is suited for milling operations on a range of materials including cast iron, non-ferrous alloys, stainless steel, heat-resistant alloys, and carbon steels, as indicated by workpiece material codes H, K, M, N, P, and S. The centercutting capability allows plunge entry, making it appropriate for slotting, profiling, and pocket milling. Its spiral flute geometry and right-hand cut with right-hand flute configuration are standard for conventional CNC milling center setups. This is a regular-length tool, suitable for standard reach applications where extended reach is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for elevated heat resistance and longer tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration during cutting\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC spindle compatibility\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 specified by SGS Series 1 tooling classification, covering cast iron, non-ferrous metals, stainless steels, heat-resistant alloys, and carbon and alloy steels.

Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before inserting or removing the tool. Verify runout and tool projection before beginning a cut, as small-diameter carbide tools are sensitive to excessive overhang and improper clamping. Follow shop safety procedures and applicable OSHA machine guarding standards during setup and operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eExtended Reach\u003c\/strong\u003e: No\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: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 30198\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51736249368882,"sku":"30198","price":33.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d676a4af274d80606c6eaa873214d298.jpg?v=1788776745","url":"https:\/\/voomisupply.com\/products\/sgs-30198-square-end-mill-1-8-inch-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
