Part of the B-333 Series Tuffy Grade carbide line, this single-end tool features a 0.0625-inch mill diameter, a 3-flute helical configuration, and a 30-degree medium helix angle. The ball nose geometry produces a 0.0313-inch nose radius, making it well suited for contoured surfaces and detail work. Right-hand cutting and right-hand flute direction are standard. Machinists and tool-and-die professionals install this mill in CNC machining centers and manual mills for precise material removal on small-profile features.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for use on cast iron and non-ferrous metals, aligning with ISO material groups K and N. Its standard-length configuration and straight-cylindrical shank fit conventional collet and end mill holder setups. The uncoated bright finish makes it appropriate for applications where coating adhesion or heat buildup is not a primary concern, and where re-sharpening is a consideration. The 0.1875-inch length of cut and 1.5-inch overall length position it for shallow-to-moderate depth passes on small workpieces or fine-detail cavities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0625-inch mill diameter with 0.0313-inch ball nose radius for contour and detail milling\u003c\/li\u003e\n\u003cli\u003e3-flute helical design with 30-degree medium helix angle for balanced chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid Tuffy Grade carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish suitable for cast iron and non-ferrous metal applications\u003c\/li\u003e\n\u003cli\u003eSingle-end, straight-cylindrical shank fits standard collet and end mill holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction; no chipbreaker, no coolant-through\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide ball end mill for use in standard collet systems accepting a 0.125-inch straight-cylindrical shank.

Power down and lock out the spindle before loading or unloading the tool. Seat the shank fully in the collet or end mill holder and torque the retention nut to the holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut, as runout is especially critical at small diameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0313 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\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\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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron; Non-Ferrous Metal\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\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 \/ -0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B-333\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 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: ROBBJACK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B-333-02\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":51972279566642,"sku":"B-333-02","price":53.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d87d0587da2ad702919951ad4b6afc8c_e4147578-a6dd-4537-aa17-85e8131d4d5b.jpg?v=1789965541","url":"https:\/\/voomisupply.com\/products\/robbjack-b-333-02-ball-end-mill-0-0625-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
