Titan Usa TE81229 Square End Mill 0.5313 in 4 Flute Cobalt

Product Description

The TITAN USA TE81229 is a cobalt square end mill designed for milling operations requiring durability and heat resistance. Built from M42 cobalt high-speed steel, it handles tough ferrous materials and interrupted cuts that standard HSS tooling cannot sustain. The cutter measures 0.5313 inches in diameter with a 1.375-inch length of cut, a 0.5-inch Weldon flat shank, and a 3.375-inch overall length. The four-flute geometry with a 30-degree right-hand helix delivers efficient chip evacuation and a smooth surface finish in a wide range of milling applications. The bright, uncoated finish makes it straightforward to inspect for wear.

This end mill is suited for manual and CNC vertical milling machines, knee mills, and machining centers used in job shops, maintenance facilities, and production environments. It is centercutting, allowing plunge entry directly into the workpiece. The Weldon flat shank seats securely in a standard end mill holder or side-lock holder, reducing pullout risk under heavy side loads. Typical applications include shoulder milling, slotting, and profiling in steel, alloy steel, cast iron, and similar materials.

Key Features

• M42 cobalt steel construction for improved hardness and heat resistance compared to standard M2 HSS
• Four flutes with a 30-degree right-hand helix for efficient chip evacuation and good surface finish
• Centercutting design allows direct plunge milling without a pre-drilled entry hole
• Weldon flat shank for positive seating in side-lock end mill holders, minimizing tool pullout
• Bright uncoated finish — easy visual inspection for wear and suitable for use with cutting fluids
• Right-hand cut and right-hand flute direction for standard spindle rotation

Compatibility

Designed for use in standard end mill holders and side-lock holders accepting a 0.5-inch shank diameter. Fits manual knee mills, vertical machining centers, and CNC milling machines configured for right-hand rotation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before changing tooling. Seat the Weldon flat fully against the set screw in the holder and torque the set screw per the holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, and confirm spindle direction is set to right-hand rotation before engaging the workpiece.
