It features a 0.06 inch cutting diameter, a 3\/32 inch (0.09 inch) length of cut, and a 30-degree helix angle that promotes chip evacuation and reduces cutting forces. The AlTiN coating adds thermal resistance and surface hardness, extending tool life in dry or high-speed cutting conditions. Three flutes provide a balance of chip clearance and rigidity at this small diameter. It is a single-end, center-cutting tool with right-hand cut and right-hand flute direction, suited for CNC machining centers and manual mills operated by machinists and toolmakers.\u003c\/p\u003e\u003cp\u003eThis end mill is sized for fine-detail work, slot milling, profiling, and plunge cutting in tight-tolerance applications. The 0.5 inch reach length and 2.5 inch overall length allow access to shallow pockets and stepped features without excessive overhang. The 1\/8 inch shank diameter fits standard ER collets and small-bore tool holders common in precision machine shops. Extended reach geometry supports work in areas where a standard stub length would not clear surrounding workpiece features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.06 inch cutting diameter for fine-detail and micro-milling applications\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated thermal resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eExtended reach design with 0.5 inch reach length for access to deeper features\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability at small diameters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a drop-in replacement or standard selection for CNC machining centers and manual mills using 1\/8 inch ER collet systems or equivalent small-bore tool holders.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank fully into the collet or tool holder and torque the retention nut per the tool holder manufacturer specification. At 0.06 inch diameter, tool runout must be minimized — check and adjust holder concentricity before cutting to prevent premature breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.09 inches (3\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 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\u003eReach Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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\u003eEnd Type\u003c\/strong\u003e: Single End\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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 34660-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51734952771890,"sku":"34660-C3","price":77.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48693790ec4e97f05d5a09a1389fd32c_f66d8a56-a033-48f9-a9c7-7e67c15b5de0.jpg?v=1788768498","url":"https:\/\/voomisupply.com\/products\/harvey-tool-34660-c3-square-end-mill-0-06-in-3-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
