The cutter measures 27\/64 inch (0.4219 inches) in diameter with a 1 inch length of cut and a 7\/16 inch straight-cylindrical shank. Overall length is 2-3\/4 inches, keeping the tool compact and rigid for general-purpose work. Manufactured from micrograin solid carbide, the 30153 delivers consistent edge retention and dimensional accuracy across demanding cutting conditions. It is uncoated and center-cutting, allowing plunge entry as well as conventional peripheral milling. Installed by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill suits a broad spectrum of material types, including cast iron and hardened materials (H), non-ferrous metals (K), stainless steel (M), non-metals and composites (N), steel (P), and high-temperature alloys (S). The right-hand cut and right-hand spiral flute geometry promote efficient chip evacuation and smooth surface finish across these material groups. Its regular-length classification and compact 2-3\/4 inch overall length make it well-suited for close-tolerance slotting, profiling, and contouring work on vertical machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for wear resistance and edge stability\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter during cuts\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with spiral flute geometry promotes chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard collet and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard collet chucks, end mill holders, and shrink-fit tooling accepting a 7\/16 inch straight shank across vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Power down and lock out the spindle before seating or removing the tool from its holder. Ensure the shank is fully engaged within the collet or holder to the minimum recommended grip depth to prevent pullout under cutting load. Do not exceed the tool manufacturer recommended depth-of-cut or feed rate for the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Inch)\u003c\/strong\u003e: 27\/64 inch (0.4219 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\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 1.0000 to 1.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\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\u003eCenter Cutting\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\u003eChipbreaker\u003c\/strong\u003e: No\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: +0.00000 \/ -0.00035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1\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\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: 30153\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51753375990066,"sku":"30153","price":103.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3fb00c94b24abdf24c62cd84395f6ab_d96f1121-0295-491d-b5bf-3b6ee378f0d1.jpg?v=1788935981","url":"https:\/\/voomisupply.com\/products\/sgs-30153-square-end-mill-27-64-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
