Robbjack MDM-201-0.5 Ball End Mill 0.0197 in 2 Flute Carbide

Product Description

The ROBBJACK MDM-201-0.5 is a solid carbide ball end mill engineered for precision die and mold work in hard materials. It features a 0.0197-inch (0.50 mm) cutting diameter with a matching 0.50 mm length of cut, a 0.25 mm nose radius, and a 2-flute helical geometry at a 30-degree helix angle. The extended-length design provides reach into deep cavities common in mold machining. A 6 mm straight-cylindrical shank seats securely in standard collet toolholders. This mill is intended for use by machinists and toolmakers running CNC milling centers in die, mold, and precision component applications.

The MDM-201-0.5 is suited for both roughing and finishing passes on hard workpiece materials, making it a practical single-tool choice for tight-tolerance cavity work. The extended-length body allows access to recessed features without sacrificing rigidity at this diameter. With a 63 mm overall length and a 6 mm shank, it fits a wide range of CNC machining centers equipped with metric collet systems. This series is designed for metric die and mold applications where micro-diameter accuracy is critical.

Key Features

• 0.50 mm (0.0197 inch) ball nose cutting diameter with 0.25 mm nose radius for fine detail work
• Solid carbide construction for rigidity and wear resistance in hard materials
• 2-flute right-hand helical geometry at 30 degrees for efficient chip evacuation
• Extended-length body at 63 mm overall length for deep cavity reach
• 6 mm straight-cylindrical shank compatible with standard metric collet toolholders
• Capable of both roughing and finishing in a single tool per MDM-201 series design intent

Compatibility

Designed as an OEM-style replacement and standard stocking tool for CNC machining centers using metric collet systems in die, mold, and precision hard-material applications. Part of the ROBBJACK MDM-201 series for metric micro-diameter end milling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the control is in a safe state before loading or unloading the tool. Seat the 6 mm shank fully into a clean, undamaged collet and torque the collet nut to the toolholder manufacturer specification. At this micro diameter, runout control is critical - verify TIR with a test indicator before commencing cuts.
