Titan Usa TC17665 Square End Mill 1 in 4 Flute Carbide

Product Description

The TITAN USA TC17665 is a solid carbide square end mill designed for high-performance milling in demanding machining applications. Built from micrograin carbide substrate and coated with AlTiN (aluminum titanium nitride), this tool handles elevated cutting temperatures while maintaining edge integrity. It features a 1 inch cutting diameter, 4-inch length of cut, 7-inch overall length, and a 30-degree helix angle. Four flutes provide a balance of chip evacuation and surface finish. Right-hand cut with upcut flute geometry makes this a standard choice for conventional and climb milling on vertical machining centers and CNC mills.

This end mill is suited for milling steel, stainless steel, cast iron, and high-temperature alloys in both roughing and finishing passes. The 1 inch shank diameter fits standard ER, Weldon, and side-lock toolholders found in production shops and job shops alike. With a 4-inch length of cut and extended reach geometry, it handles deep-pocket milling, slot milling, and shoulder milling where shorter tools cannot reach. Single-end construction means the tool is replaced rather than indexed when worn.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance
• AlTiN coating extends tool life in ferrous and high-temperature alloy applications
• 30-degree helix angle balances cutting forces and chip flow
• Centercutting geometry allows plunge entry
• Right-hand cut, upcut flute direction compatible with standard spindle rotation
• 4-inch length of cut enables deep-pocket and deep-slot operations

Compatibility

Designed for use in CNC vertical machining centers, knee mills, and any machine tool accepting a 1 inch round shank toolholder. Confirm spindle speed, feed rate, and toolholder runout specifications with machine documentation before use.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the machine in an e-stop or powered-down state. Secure the shank in a clean, properly torqued toolholder to manufacturer specifications for that holder type. Inspect the collet or chuck bore for wear or runout before seating the tool. Follow applicable shop safety procedures and machine tool manufacturer guidelines for tool change protocol.
