Robbjack B-333-02 Ball End Mill 0.0625 in 3 Flute Carbide

Product Description

The ROBBJACK B-333-02 is a solid carbide ball end mill engineered for precision milling in both roughing and finishing operations. 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.

This 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.

Key Features

• 0.0625-inch mill diameter with 0.0313-inch ball nose radius for contour and detail milling
• 3-flute helical design with 30-degree medium helix angle for balanced chip evacuation
• Solid Tuffy Grade carbide construction for rigidity and wear resistance
• Uncoated bright finish suitable for cast iron and non-ferrous metal applications
• Single-end, straight-cylindrical shank fits standard collet and end mill holders
• Right-hand cut and right-hand flute direction; no chipbreaker, no coolant-through

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard collet systems accepting a 0.125-inch straight-cylindrical shank. Rated for cast iron and non-ferrous metal workpiece materials per manufacturer specification.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. 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.
