Built from solid carbide with an AlTiN coating, it delivers hardness and heat resistance suited for cutting steel, stainless steel, cast iron, aluminum, non-ferrous alloys, and carbon fiber reinforced polymer (CFRP) materials. The tool measures 0.0625 inches in cutting diameter with a 5\/16-inch length of cut and a 2.5-inch overall length. Four spiral flutes and a 30-degree helix angle combine to produce clean chip evacuation and stable cutting performance at reduced diameters. Licensed machinists and CNC operators install this tool in machining centers and mill setups requiring miniature end mill geometry.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for detailed contouring, slotting, and profiling operations where small cutter diameters are required. Its centercutting capability allows direct plunge entry into workpiece material. The long-flute design within the miniature series supports applications where added reach is needed without stepping up to a larger shank. Primary workpiece materials include steel (P), stainless steel (M), cast iron (K), aluminum and non-ferrous materials (N), and CFRP materials (C). The 1\/8-inch shank diameter is compatible with standard collets and end mill holders used in CNC and manual milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides oxidation resistance and extended tool life in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge milling without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes for improved finish and material removal rate in miniature applications\u003c\/li\u003e\n  \u003cli\u003eSingle-end, right-hand cut with right-hand flute orientation for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style miniature square end mill compatible with standard 1\/8-inch collets and end mill holders in CNC machining centers and manual milling machines.

Ensure the spindle is fully stopped and the machine is powered down or placed in an e-stop state before changing tooling. Seat the 1\/8-inch shank fully and evenly in the collet or end mill holder and torque the retention nut per the toolholder manufacturer specifications. At small diameters, runout control is critical — verify tool runout with a dial indicator before beginning a production cut to avoid premature tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/16 inch (0.3120 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: 2.5 inches\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eVariable Index\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\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Square - Long Flute\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: 0.02 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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 834162-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728784523570,"sku":"834162-C3","price":67.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e8812d2b2470bfaa489e415e80bcb36_6901cc67-9c8e-449c-b9c5-51113385c674.jpg?v=1788696187","url":"https:\/\/voomisupply.com\/products\/harvey-tool-834162-c3-square-end-mill-1-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
