It features a 31\/64 inch (0.4844 inch) cutting diameter, a 1 inch length of cut, and a 1\/2 inch straight-cylindrical shank. The AlTiN coating improves heat resistance and extends tool life in demanding cutting conditions. Four spiral flutes with a 30-degree helix angle and variable index geometry promote chip evacuation and reduce chatter. Right-hand cut and right-hand flute orientation follow standard milling conventions. Micrograin carbide construction supports tight tolerances and consistent edge integrity across production runs. This tool is installed and used by machinists, toolroom operators, and CNC programmers.\u003c\/p\u003e\u003cp\u003eThe SGS 30021 is suited for milling operations across a broad range of workpiece materials. Its primary workpiece material codes cover hardened steels (H), cast iron (K), stainless steel (M), non-ferrous metals (N), carbon and alloy steels (P), and heat-resistant superalloys (S). The regular length designation and 3 inch overall length make it practical for standard-depth peripheral and slot milling setups where extended reach is not required. It is centercutting, allowing plunge entry into the workpiece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for dimensional stability and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance in high-speed and dry cutting applications\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — standard CNC spindle compatible\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, covering steels, cast irons, stainless alloys, non-ferrous metals, and heat-resistant superalloys.

Seat the 1\/2 inch shank fully into the holder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cycle. Inspect the cutting edges for chips or coating damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 31\/64 inch (0.4844 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 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: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\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: 30021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51734042050866,"sku":"30021","price":143.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1c2da362743a8bad013a61b522ebc55_9b063d85-e1dc-4831-95a8-072b782f4266.jpg?v=1788760630","url":"https:\/\/voomisupply.com\/products\/sgs-30021-square-end-mill-31-64-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
