Robbjack T12-203-05 Square End Mill 5/32 in 2 Flute Carbide

Product Description

The ROBBJACK T12-203-05 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Part of the T12-203 series, this tool features a 5/32 inch (0.1563 inch) cutting diameter, a 9/16 inch length of cut, and a 3/8 inch straight cylindrical shank. The 2-flute, right-hand spiral flute geometry promotes efficient chip evacuation, while the centercutting capability allows the tool to plunge directly into workpiece material. The Tuffy material grade solid carbide construction delivers rigidity and wear resistance across a range of ferrous and non-ferrous materials. This end mill is sold uncoated and is ready for immediate use.

This end mill is suited for slot milling, profiling, and light pocketing operations on machining centers and manual mills. The 2-1/2 inch overall length and regular length type make it appropriate for standard-reach applications where minimal tool overhang is preferred. The 30-degree helix angle balances cutting forces and surface finish across common shop materials. Professional machinists and CNC operators working in job shops, toolrooms, or production environments will find this tool a practical fit for general-purpose milling tasks.

Key Features

• Solid carbide Tuffy grade construction for rigidity and extended tool life
• 5/32 inch cutting diameter with a tight mill diameter tolerance of +0.001 / -0.000 inch
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut, right-hand spiral flute with 30-degree helix angle
• 2-flute configuration promotes chip clearance in slotting and profiling cuts
• Straight cylindrical 3/8 inch shank fits standard collets and end mill holders

Compatibility

Designed as an OEM-style replacement or direct application tool for standard 3/8 inch collet or end mill holder setups on vertical machining centers and manual knee mills requiring a 5/32 inch square end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism according to the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning cuts to protect both the tool and the workpiece.
