Robbjack TR-404-16 Square End Mill 1/2 in 4 Flute Carbide

Product Description

The ROBBJACK TR-404-16 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. Part of the TR-404 series, it features a 0.5-inch diameter, a 1-inch length of cut, and a 3-inch overall length. The four-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and stable cutting at higher feed rates. Manufactured from ROBBJACK Tuffy-grade solid carbide, this uncoated end mill is centercutting, allowing plunge entry as well as peripheral and slot milling. It is sized with a 0.5-inch straight cylindrical shank for direct collet or end mill holder mounting on CNC machining centers and manual mills.

The TR-404-16 is suited for general-purpose milling operations in job shop, production, and toolroom environments. Its regular-length geometry makes it a practical choice for face milling, profiling, contouring, and slotting applications where a compact, rigid setup is required. The uncoated carbide surface is appropriate for use with cutting fluids on aluminum, brass, steel, and similar materials. This end mill is typically installed and run by machinists and CNC operators working with vertical or horizontal machining centers.

Key Features

• Solid Tuffy-grade carbide construction for rigidity and wear resistance
• 4-flute spiral configuration with 30-degree helix angle for efficient chip removal
• Centercutting design allows plunge, slot, and peripheral milling
• Right-hand cut and right-hand flute orientation for standard spindle operation
• Straight cylindrical shank fits standard collets and end mill holders
• Uncoated finish compatible with flood coolant and cutting oil applications

Compatibility

Designed as an OEM-style replacement and standard tooling option for use in any machine tool accepting a 0.5-inch straight shank end mill, including CNC machining centers, knee mills, and manual vertical mills.

Installation Notes

Installation is performed by machinists using a collet chuck, end mill holder, or Weldon-style holder rated for the 0.5-inch shank diameter. Verify runout with a dial indicator after securing the tool before beginning a cut. Power down and lock out the spindle before changing tooling. Do not exceed manufacturer feed and speed recommendations for the workpiece material and depth of cut.
