It carries a 7\/64-inch (0.1094 inches) cutting diameter and a 3\/8-inch length of cut, making it well suited for small-diameter milling work where rigidity and edge retention are critical. The 30-degree helix angle promotes chip evacuation and reduces cutting forces, and the center-cutting geometry allows plunge entry as well as peripheral cuts. Machinists and tool-and-die professionals will recognize this as a general-purpose finishing cutter built for demanding work materials.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for machining steel, stainless steel, cast iron, and high-temperature alloys, covering ISO material codes P, M, K, and S. The SIRON-A coating adds wear resistance and thermal stability when cutting these harder and more abrasive materials. With a 1\/8-inch straight-cylindrical shank, it fits standard ER collets and toolholders common in CNC machining centers, vertical mills, and high-speed spindles used in precision job shop and production environments. The regular-length geometry and 1.5-inch overall length are appropriate for shallow-to-moderate pocket depths.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eSIRON-A coating provides thermal resistance and reduces adhesive wear on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eFour right-hand helical flutes with 30-degree helix angle promote efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with straight-cylindrical shank compatible with standard collet toolholders\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of -0.0005\/0.0005 inches ensures consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with 1\/8-inch collet or end mill holders accepting straight-cylindrical shanks per ANSI B94.19.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or toolholder and torque the retention nut per the toolholder manufacturer's specification. Verify runout with a dial indicator before cutting; this tool carries a maximum TIR of 0.0005 inches and requires a clean, undamaged collet bore to maintain that tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1094 inches (7\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5000 inches (1-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.1144 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.3750 inches (3\/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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\/Finish\u003c\/strong\u003e: SIRON-A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eCoolant Through\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: -0.0005\/0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: ANSI B94.19\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: NAS 986\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\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: C5141\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10268271\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564125061426,"sku":"10268271","price":26.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39f7ab82c3479f772bbf24756f599056_812eaba8-2bc1-49f1-9053-fb5d66585ce8.jpg?v=1786511572","url":"https:\/\/voomisupply.com\/products\/seco-10268271-square-end-mill-7-64-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
