Titan Usa TC74126 Corner Radius End Mill 5/16 in 4 Flute

Product Description

The TITAN USA TC74126 is a solid carbide corner radius end mill designed for demanding material removal in superalloys, titanium alloys, stainless steel, cast iron, alloy steel, and Inconel. It carries a 5/16 inch diameter with a 4-flute, right-hand spiral configuration and a 30-degree helix angle suited for both roughing and finishing passes. The AlTiN (aluminum titanium nitride) PVD coating improves heat resistance and extends tool life in high-temperature alloy cutting. With a corner radius of 0.0150 inches, it produces a controlled edge blend that reduces stress concentration at the workpiece corner. Machinists and tool-and-die technicians install this end mill using standard straight-cylindrical shank toolholders.

This end mill is built for use in CNC machining centers and manual mills where ferrous metals and high-temperature alloys are the primary workpiece materials. The single-end, non-centercutting design means it is not suited for direct plunge entry and is best applied in peripheral, slot, and contour milling operations. Its regular length classification and 13/16 inch length of cut make it appropriate for moderate-depth passes in production and job-shop environments where tool rigidity and surface finish consistency are both priorities. The Series TC designation places it within TITAN USA's line of solid carbide tooling for difficult-to-machine materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN PVD coating enhances thermal resistance during high-speed cuts in superalloys and stainless steel
• 0.0150 inch corner radius reduces edge chipping and stress risers at workpiece corners
• 4-flute, right-hand spiral with 30-degree helix angle balances chip evacuation and surface finish
• Non-centercutting, single-end design optimized for peripheral and contour milling operations
• Straight-cylindrical shank compatible with standard ER collets and milling toolholders

Compatibility

Designed for use with standard straight-cylindrical shank toolholders. Primary workpiece materials include superalloys, titanium alloy, Inconel, stainless steel, cast iron, alloy steel, and other ferrous metals.

Installation Notes

Installation is performed by machinists or tooling technicians using a compatible collet chuck or end mill holder sized for a 5/16 inch shank. Ensure the machine spindle is fully stopped and the tool is secured to the manufacturer-recommended clamping depth before operation. This is a non-centercutting tool and must not be used for direct axial plunge cuts. Verify runout with a dial indicator after tool installation to protect both the tool and the workpiece surface finish.
