Part of the SB335 series, it features a 1\/8 inch diameter with a 1\/2 inch length of cut and a 35-degree medium helix angle. The AlTiN PVD coating provides thermal resistance and wear protection during demanding cutting operations. With three flutes and a right-hand spiral flute direction, this tool supports both roughing and finishing material removal in a single-end configuration. Machinists and tool-and-die professionals rely on this style of end mill for contoured and profile milling where a ball nose geometry is required.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers handling ferrous and non-ferrous workpieces. The long length type and 1\/2 inch reach length make it appropriate for applications requiring extended access into pockets or along profiled surfaces. The straight cylindrical shank with a 1\/8 inch diameter seats directly into standard collet systems. No coolant-through capability is present, so flood or mist coolant should be applied externally. The SB335 series targets applications in steel, cast iron, and non-ferrous metals where a compact, coated carbide tool is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability in precision milling\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for elevated thermal resistance and extended tool life in steel and cast iron\u003c\/li\u003e\n\u003cli\u003e3-flute, right-hand spiral geometry supports both roughing and finishing passes\u003c\/li\u003e\n\u003cli\u003e35-degree medium helix angle balances chip evacuation and cutting load\u003c\/li\u003e\n\u003cli\u003eBall nose profile enables contour, profile, and 3D surface milling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical 1\/8 inch shank fits standard collet toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide ball end mill for use in CNC machining centers and manual mills with compatible collet or toolholder systems accepting a 1\/8 inch straight shank.

The machine spindle must be fully stopped and locked out before inserting or removing the tool from the collet or toolholder. Ensure the collet bore matches the 1\/8 inch shank diameter and that the tool is seated to the correct gauge length before tightening. Follow machine manufacturer torque specifications for the collet nut and inspect runout after installation; maximum TIR for this tool is 0.0005 inches.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 inches (1\/2 inches)\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 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 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\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 \/ -0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SB335\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 17003781\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557962580274,"sku":"17003781","price":62.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac10cc488d6f4b8e34b313f17b56869a.jpg?v=1786399577","url":"https:\/\/voomisupply.com\/products\/seco-17003781-ball-end-mill-1-8-in-3-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
