It carries a 1\/64 inch cutting diameter with a 1\/32 inch length of cut and a 1\/8 inch straight shank, giving it a slender profile suited for fine-detail slot milling, profiling, and plunge operations. Four right-hand spiral flutes at a 30-degree helix angle promote chip evacuation and surface finish quality. The bright uncoated finish means it is ready to run as received, with no coating buildup to affect dimensional accuracy at this micro scale. Centercutting geometry allows direct plunge entry into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for stub-length applications where rigidity and runout control are critical. Primary workpiece material ratings cover cast iron, stainless steel, aluminum and non-ferrous alloys, carbon and alloy steel, and high-temperature alloys, making it a versatile choice for mold and die shops, precision machining cells, and aerospace component work. The tight diameter tolerance of plus or minus 0.0005 inches and a maximum TIR of 0.0001 inches support consistent dimensional results across production runs. It is installed in a standard 1\/8 inch collet or tool holder on a CNC machining center or high-speed spindle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and edge retention at small diameters\u003c\/li\u003e\n  \u003cli\u003eFour right-hand spiral flutes with 30-degree helix angle for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains true ground dimensions with no coating offset\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance of plus 0.0005 and minus 0.0005 inches for dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eRated for cast iron, stainless steel, aluminum, steel, and high-temperature alloys\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/8 inch collet systems and tool holders on CNC machining centers and high-speed spindles.

Ensure the spindle and tool holder are clean and free of debris before seating the shank to the full recommended grip depth. At this micro diameter, runout at the tool tip must be verified with a dial indicator before cutting; excessive runout will cause premature breakage. Follow machine tool manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/64 inch (0.0200 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/32 inch (0.0300 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 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\u003eFlute Type\u003c\/strong\u003e: Spiral, 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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 \/ minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: minus 0.0001 \/ minus 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.0600 \/ minus 0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MES430\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 17002745\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558929105202,"sku":"17002745","price":39.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc2a83fc88ea5b79ebab0f7237554d14_2f539dd1-e80f-4716-818d-5fdb69ad754e.jpg?v=1786423209","url":"https:\/\/voomisupply.com\/products\/seco-17002745-square-end-mill-1-64-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
