Titan Usa TC90548 Square End Mill 0.75in 4 Flute Solid Carbide

Product Description

The TITAN USA TC90548 is a 4-flute solid carbide square end mill designed for high-performance milling in metalworking and machining applications. It features a 0.75 inch cutting diameter and a 1.5 inch length of cut, making it well suited for slotting, profiling, and peripheral milling operations. The tool is coated with TiCN (Titanium Carbonitride), which improves surface hardness and wear resistance compared to uncoated carbide. The micrograin carbide substrate supports edge integrity at higher feed rates and cutting speeds. This end mill is installed and used by machinists, tool and die makers, and CNC operators working on milling machines and machining centers.

This end mill is built for right-hand cut, right-hand flute, upcut operations with a 30-degree helix angle. The upcut flute geometry promotes chip evacuation away from the workpiece, reducing heat buildup and recutting of chips. It is centercutting, which allows for plunge milling in addition to standard peripheral and slot milling. The 0.75 inch shank diameter matches the cutting diameter, providing a rigid, balanced tool setup. Typical applications include steel, stainless steel, cast iron, and other ferrous materials where TiCN coating delivers meaningful performance gains.

Key Features

• 0.75 inch cutting diameter with 1.5 inch length of cut for medium-depth milling operations
• 4-flute geometry balances material removal rate with chip clearance
• TiCN coating increases surface hardness and extends tool life in ferrous materials
• Micrograin solid carbide substrate maintains edge sharpness under load
• 30-degree helix angle with upcut flute direction promotes efficient chip evacuation
• Centercutting design enables plunge entry without a pre-drilled pilot hole

Compatibility

Designed as a standard 0.75 inch shank square end mill compatible with milling machines and CNC machining centers that accept 3/4 inch collets or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a properly sized collet or end mill holder rated for the 0.75 inch shank diameter, and torque the retention hardware according to the toolholder manufacturer specifications. Inspect the cutting edges for chipping or wear before each use and replace the tool if edge integrity is compromised.
