Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, this tool delivers hardness and heat resistance needed for cutting ferrous and non-ferrous materials at high speeds. The 1\/64 inch cutting diameter and 1\/32 inch length of cut make it suited for fine detail work, micro-slot milling, and tight-tolerance profiling. A 30-degree helix angle and centercutting geometry allow both plunge and lateral cutting. CNC machinists and toolroom operators are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and high-speed spindle applications where small-diameter tooling is required. The 1\/8 inch shank diameter fits standard collet systems commonly found in vertical machining centers and CNC routers. Its 1-1\/2 inch overall length provides adequate rigidity for micro-milling operations in mold making, medical component machining, and precision part production. Right-hand cut and right-hand flute orientation follow standard convention for most production setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in small-diameter tooling\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides heat resistance and extends tool life in dry or semi-dry cutting conditions\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle improves chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e1\/64 inch (0.0200 inch \/ 0.5 mm) cutting diameter for micro and fine-detail milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration compatible with standard machine spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and high-speed spindle setups equipped with 1\/8 inch collet or ER collet systems accepting standard shank end mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified CNC machinist or toolroom professional. Ensure the machine spindle is fully powered down and locked out before loading or unloading the tool. Use a calibrated torque wrench and the appropriate collet nut wrench when seating the shank in the collet to avoid runout. At this diameter, even minor runout or improper seating can cause immediate tool breakage — verify tool projection and runout with a dial indicator before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0200 inches (1\/64 inch \/ 0.5 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0300 inches (1\/32 inch)\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: 1.5 inches (1-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\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\u003eExtended Reach\u003c\/strong\u003e: No\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: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 13920-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51731122487602,"sku":"13920-C3","price":54.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e6c2648a48988cfc4fa09eed2e0bf49.jpg?v=1788727196","url":"https:\/\/voomisupply.com\/products\/harvey-tool-13920-c3-square-end-mill-1-64-in-2-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
