It cuts at a 10-degree taper per side with a 0.060-inch small end diameter and a 5\/16-inch (0.312 inch) length of cut. The three-flute design provides a balance of chip evacuation and surface finish at the small diameters typical of miniature toolpath applications. A 30-degree helix angle supports smooth cutting action in both ferrous and non-ferrous materials. This tool is part of the Harvey Tool Miniature End Mills - Tapered - Square series and is intended for use by machinists and tool-and-die professionals working on CNC milling centers.\u003c\/p\u003e\u003cp\u003eThis tapered square-end mill is suited for creating draft angles, tapered walls, and rib features on small molds, dies, and precision components. The square end geometry delivers a flat-bottomed finish at the base of a tapered pocket or wall. The 3\/16-inch shank diameter and 2-inch overall length make it compatible with standard collet toolholders used in benchtop and full-size CNC machining centers running miniature toolpaths. It is most commonly applied in mold-making, medical device, aerospace, and prototype machining environments where small end diameter accuracy is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-degree taper per side for consistent draft angle in a single pass\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance at small diameters\u003c\/li\u003e\n\u003cli\u003eThree flutes with 30-degree helix angle balance chip clearance and finish quality\u003c\/li\u003e\n\u003cli\u003e0.060-inch small end diameter supports fine-detail and micro-feature milling\u003c\/li\u003e\n\u003cli\u003eSquare end geometry produces a flat floor at the base of tapered features\u003c\/li\u003e\n\u003cli\u003e3\/16-inch shank fits standard ER and straight-bore collet toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide tapered end mill in the Harvey Tool Miniature End Mills - Tapered - Square series, compatible with CNC milling machines using 3\/16-inch collet or toolholder bores.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with CNC toolholder setup and runout requirements. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Seat the shank fully into the collet to the recommended engagement depth to minimize deflection at the small end diameter. Verify runout with a dial indicator before beginning a production cut, as small-diameter tapered tools are sensitive to toolholder concentricity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/16 inches (0.312 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.060 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: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Tapered - Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 988260-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51747721380146,"sku":"988260-C6","price":129.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb2154eeaed3a9c186febd72535a30bb_3b70540b-6d57-4da4-bbf5-5f64e65304c4.jpg?v=1788884659","url":"https:\/\/voomisupply.com\/products\/harvey-tool-988260-c6-tapered-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
