Built with 4 flutes and coated in AlTiN (Aluminum Titanium Nitride) finish, this tool delivers high heat resistance and extended tool life in demanding cutting applications. The 3\/16 inch cutter diameter and matching 3\/16 inch shank diameter make it a compact, rigid choice for small-diameter counterboring work. Machining professionals and toolroom technicians use this counterbore on CNC machining centers and manual mills where tight tolerances and clean floor finishes are required.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is suited for metalworking applications in job shop, manufacturing, and maintenance environments. The AlTiN coating improves performance in ferrous and hard materials, including alloy steels and stainless. With a 3\/4 inch flute length and 3 inch overall length, the 25512-C3 handles typical counterboring depths on medium-duty workpieces. It is appropriate for use by machinists and tool and die makers working with small-format components requiring precise fastener seat geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in metal cutting\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high-temperature resistance and extended cutting life\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry delivers smooth floor finish in counterbored holes\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch cutter diameter matches 3\/16 inch shank for a compact, balanced profile\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch flute length accommodates standard counterboring depth requirements\u003c\/li\u003e\n  \u003cli\u003e3 inch overall length suits most machining center and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid counterbore for use in CNC machining centers and manual milling machines accepting a 3\/16 inch shank diameter toolholder or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Secure the 3\/16 inch shank in a properly sized collet or endmill holder, ensuring full and even clamping contact before operation. Confirm spindle RPM and feed rate are appropriate for the workpiece material and cutter diameter before engaging the cut. Inspect the cutting edges and coating for wear or chipping before each use and replace the tool if damage is present.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (Aluminum Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 25512-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51750175342898,"sku":"25512-C3","price":95.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f67e38dd977e8c7777170116450f3a8_9dfc0eab-dcec-4410-9eb1-697a5600392c.jpg?v=1788914085","url":"https:\/\/voomisupply.com\/products\/harvey-tool-25512-c3-solid-carbide-counterbore-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
