Robbjack DM-201-03 Ball End Mill 0.0938 in 2 Flute Carbide

Product Description

The ROBBJACK DM-201-03 is a 2-flute solid carbide ball end mill designed for precision milling in hard and difficult-to-machine materials. It features a 0.0938-inch mill diameter, a 0.0938-inch length of cut, and a 0.0469-inch nose radius that produces accurate contoured and profiled surfaces. The extended-length design, with a 2.5-inch overall length and a 0.25-inch straight-cylindrical shank, provides reach into deeper cavities and die or mold pockets. A 30-degree medium helix supports both roughing and finishing passes. This tool is intended for use by machinists and toolmakers working in CNC machining centers and high-precision milling applications.

The DM-201-03 is suited for die and mold work where tight tolerances and fine surface finish are required in hard workpiece materials. The single-end configuration and extended reach make it practical for deep-cavity contouring, 3D profiling, and detail work in tool steels and other hard alloys. The Series DM-201 designation places this mill within a family engineered specifically for extended-reach die and mold applications. It operates in a right-hand cutting and right-hand flute direction, which is standard for conventional CNC milling setups.

Key Features

• 0.0938-inch ball end diameter with a 0.0469-inch nose radius for accurate contour milling
• Solid carbide construction for rigidity and wear resistance in hard materials
• 30-degree medium helix angle supports both roughing and finishing in a single tool
• Extended-length design with 2.5-inch overall length for deep-cavity reach
• Right-hand cut and right-hand flute direction for standard CNC compatibility
• Mill diameter tolerance of plus 0.0003 and minus 0.0003 inches for consistent dimensional accuracy

Compatibility

Designed as an OEM-style solid carbide ball end mill for CNC machining centers requiring extended-reach, small-diameter tooling in hard workpiece material applications.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Use a properly sized collet or end mill holder matched to the 0.25-inch shank diameter to ensure runout is minimized. Verify tool projection and reach clearance before beginning a cutting program, particularly in deep-cavity or die-and-mold setups. Follow the machine manufacturer guidelines and applicable shop safety procedures when setting tool offsets and depth of cut parameters.
