Built from solid carbide, it runs a 0.03125-inch (1\/32 inch) cutting diameter with a 0.045-inch length of cut and a 30-degree helix angle. The AlTiN coating improves heat resistance and extends tool life in ferrous and high-temperature alloy materials. With a 1\/8-inch shank diameter and 2.5-inch overall length, this end mill fits standard collet systems used on CNC machining centers and precision manual mills. Installation and operation are handled by machinists and CNC programmers working in tool and die, mold, and precision component applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finishing and semi-finishing passes in small-cavity and micro-feature milling. The 3-flute configuration balances chip evacuation and finish quality at the small diameters where tool deflection and chip packing are primary concerns. The extended reach design, with a 0.375-inch reach length, allows access to recessed features and stepped pockets that shorter stub-length tools cannot reach. It is centercutting, enabling plunge entry and ramp milling strategies without requiring a pre-drilled start hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance at 0.03125-inch diameter\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for elevated heat resistance in ferrous, stainless, and high-temp alloy cuts\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry balances chip clearance and surface finish at micro-scale diameters\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle reduces cutting forces and supports smooth chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge, ramp, and helical interpolation entry\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 0.375-inch reach length for recessed pocket and deep-feature access\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute  -  compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and precision mills with 1\/8-inch collet or end mill holders.

Confirm spindle rotation is set to right-hand before engaging the cut. At 0.03125-inch diameter, feed rates and depth of cut must be carefully calculated; consult manufacturer feeds-and-speeds data for the specific workpiece material. Handle micro-diameter carbide tooling with care to avoid chipping the flutes during loading and unloading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.03125 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.045 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\/Finish\u003c\/strong\u003e: AlTiN\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\u003eExtended Reach\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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 35430-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51740643623218,"sku":"35430-C3","price":80.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c192dec0c866eb584886d76f97252354_ca4ab70b-2efc-4d61-a11c-6dd825174491.jpg?v=1788826422","url":"https:\/\/voomisupply.com\/products\/harvey-tool-35430-c3-square-end-mill-1-32-in-3-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
