Robbjack TR-404-14 Square End Mill 7/16 in 4 Flute Carbide

Product Description

The ROBBJACK TR-404-14 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. It features a 7/16 inch (0.4375 inch) cutting diameter and a 1 inch length of cut, making it well suited for slotting, profiling, and peripheral milling. The four-flute geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Centercutting capability allows the tool to plunge directly into a workpiece. This end mill is uncoated and runs right-hand cut with right-hand flute direction, conforming to standard CNC machining setups.

The TR-404-14 is intended for use in CNC machining centers and manual knee mills where a regular-length, general-purpose end mill is required. Its 7/16 inch shank diameter matches the cutting diameter for straightforward collet or end mill holder setup. The tool is suitable for a range of ferrous and non-ferrous applications in job shop, production, and toolroom environments. No extended reach is built in, keeping rigidity high for demanding cuts in close-tolerance work.

Key Features

• Solid carbide construction for rigidity and wear resistance
• 4-flute spiral geometry with 30-degree helix for efficient chip flow
• Centercutting design allows direct plunge entry
• Right-hand cut and right-hand flute direction for standard spindle use
• Uncoated finish suitable for a wide range of base materials
• Mill diameter tolerance of +0.001 / -0.000 inches for consistent fit and finish

Compatibility

Designed as a general-purpose replacement or standard-stock square end mill in the ROBBJACK TR-404 series, compatible with any CNC or manual milling machine equipped with a 7/16 inch collet, end mill holder, or equivalent toolholding system.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the collet or holder to the recommended gauge line depth before torquing the nut or drawbar per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
