The tool features a 0.1875 inch (3\/16 inch) diameter, a 1.5 inch length of cut, and a 3.0 inch overall length. Four helical flutes with a variable helix geometry improve chip evacuation and reduce harmonic vibration during cutting. An AlTiN PVD coating provides thermal resistance and extended tool life in demanding ferrous and hard-material applications. This end mill is specified for machinists and CNC operators working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 34112-C3 falls within the HARVEY TOOL Miniature End Mills - Ball - Long Flute series. It is suited for finishing passes in molds, dies, and complex contoured workpieces where a long-flute reach and ball-nose profile are required. The long-flute configuration allows access to deeper cavities and side walls compared to standard-length tooling. Right-hand cut and right-hand flute direction make it compatible with conventional CNC machining center spindle rotation. No coolant-through feature; external flood or mist coolant is the standard approach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1875 inch ball-nose diameter with a 0.0938 inch nose radius for accurate contour finishing\u003c\/li\u003e\n  \u003cli\u003eVariable helix geometry reduces chatter and improves surface finish in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for high heat resistance and extended wear life in ferrous and hard workpiece materials\u003c\/li\u003e\n  \u003cli\u003e1.5 inch reach length enables deep-cavity and side-wall finishing\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and precision at miniature diameters\u003c\/li\u003e\n  \u003cli\u003eSingle-end, straight-cylindrical shank fits standard collet and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/16 inch (h6 tolerance) collet chucks and end mill holders on CNC machining centers.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth before torquing the nut. Confirm runout with a dial indicator before production to protect the tool and workpiece at this miniature diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 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: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 20 degrees (variable)\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\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: 34112-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51755865964850,"sku":"34112-C3","price":79.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47b2fc20a2c8ea957564329ab84fe923_c4f5fefc-d3fd-4aa5-9125-44cdadda86f8.jpg?v=1788960717","url":"https:\/\/voomisupply.com\/products\/harvey-tool-34112-c3-ball-end-mill-0-1875-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
