Robbjack T12-201-04 Square End Mill 1/8 Inch 2 Flute Carbide

Product Description

The ROBBJACK T12-201-04 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard material applications. Part of the T12-201 series, this stub-length end mill features a 0.125 inch cutting diameter, a 0.250 inch length of cut, and a 0.375 inch straight-cylindrical shank. The 2-flute geometry and 30-degree helix angle promote efficient chip evacuation in slotting, profiling, and plunge-cutting operations. Centercutting capability allows direct plunge entry without a pilot hole. The uncoated solid carbide construction in ROBBJACK Tuffy grade delivers consistent edge integrity in demanding cutting conditions.

This end mill is suited for close-tolerance machining in CNC milling centers and manual mills where a small-diameter, stub-length tool is required. The 0.375 inch shank accommodates standard collet and end mill holder setups. Its right-hand cut and right-hand spiral flute configuration is compatible with conventional CNC spindle rotation. Typical applications include slot milling, contour profiling, and pocketing in ferrous and non-ferrous workpieces where controlled reach and rigidity are priorities.

Key Features

• Solid carbide Tuffy-grade construction for edge strength and wear resistance
• 2-flute, 30-degree helix spiral flute design for efficient chip clearance
• Centercutting geometry enables direct plunge entry
• Stub length configuration maximizes rigidity and reduces deflection
• Right-hand cut and right-hand flute for standard CNC spindle compatibility
• Straight-cylindrical shank fits standard collet and end mill holders

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 0.375 inch shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the end mill. Verify collet or holder bore size matches the 0.375 inch shank diameter and that tool runout is within acceptable tolerance before commencing cutting operations. Follow applicable shop safety practices and machine guarding requirements during setup.
