It features a 27\/64 inch (0.4219 inch) cutting diameter, a 1 inch length of cut, and a 2-3\/4 inch overall length. The four-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and surface finish quality. A titanium nitride (TiN) coating improves surface hardness and wear resistance. The micrograin carbide substrate and variable index flute spacing help reduce chatter during aggressive cuts. This end mill is installed and used by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe SGS 39153 is suited for milling operations on a broad range of workpiece materials including cast iron, non-ferrous metals, stainless steel, high-temperature alloys, and steel. Its centercutting capability allows for plunge entry as well as conventional side milling and slotting. The straight cylindrical shank accommodates standard collet chucks and end mill holders. Regular length classification makes it a practical choice for general-purpose milling where extended reach is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e27\/64 inch (0.4219 inch) cutting diameter with +0.000 \/ -0.002 inch mill diameter tolerance\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand cut, right-hand spiral flute with 30-degree helix angle\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN coating for improved surface hardness and tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling and slotting entry\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter during cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with primary workpiece material codes H, K, M, N, P, and S, covering cast iron, non-ferrous metals, stainless steel, high-temperature alloys, and general steel.

Before mounting, power down and lock out the spindle per machine-specific lockout\/tagout procedures. Seat the shank fully into the collet or end mill holder and torque the retention hardware according to the toolholder manufacturer's specifications. Verify runout at the cutting diameter before beginning a new operation, as excessive runout accelerates edge wear and degrades surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 27\/64 inch (0.4219 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (0.4375 inch decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 1.0000 - 1.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00035 inch\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible 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: 39153\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51748353311026,"sku":"39153","price":114.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3fb00c94b24abdf24c62cd84395f6ab_d3056715-102c-438f-84cf-ffd7a71d784b.jpg?v=1788892846","url":"https:\/\/voomisupply.com\/products\/sgs-39153-square-end-mill-27-64-in-4-flute-solid-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
