Robbjack DM-201-12 Ball End Mill 0.375 in 2 Flute Carbide

Product Description

The ROBBJACK DM-201-12 is a 2-flute solid carbide ball end mill engineered for die and mold work in hard materials. It carries a 0.375-inch mill diameter with a matching 0.375-inch shank diameter and an extended overall length of 3.5 inches, giving machinists additional reach for deep-cavity and contoured-surface work. The 30-degree medium helix angle promotes efficient chip evacuation while maintaining edge stability in demanding cuts. Right-hand cutting and right-hand flute direction make it compatible with standard CNC and manual milling setups. This is a single-end tool rated for both roughing and finishing passes on hard workpiece materials.

The DM-201-12 is suited for mold making, die sinking, and precision contour milling in hard steels and similar materials where carbide rigidity and reach length are critical. The extended-length Series DM-201 design is aimed at production machining environments and tool rooms where machinists need to reach deep pockets without sacrificing tool stiffness. The 0.1875-inch nose radius produces a consistent ball profile at the cutting tip for smooth 3D surface finishes.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 0.375-inch ball end diameter with 0.1875-inch nose radius for accurate 3D contouring
• Extended overall length of 3.5 inches provides deep-cavity reach
• 30-degree medium helix angle supports efficient chip flow on roughing and finishing passes
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Single-end design; Series DM-201 extended-length die and mold classification

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 0.375-inch straight cylindrical shank, specifically within the ROBBJACK Series DM-201 extended-length die and mold end mill family.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the spindle before inserting or removing the tool from the collet or tool holder. Verify collet bore and holder bore match the 0.375-inch shank diameter before clamping. Follow the machine manufacturer and tooling manufacturer guidelines for runout tolerances and clamping torque; improper clamping can cause tool pullout or breakage at extended lengths.
