Harvey Tool 972493-C3 Square End Mill 3/32 in 5 Flute Altin

Product Description

The HARVEY TOOL 972493-C3 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 3/32-inch (0.0930 inch) cutting diameter and a 1/2-inch length of cut, this single-end tool delivers tight-tolerance performance in ferrous and non-ferrous materials. The AlTiN coating provides heat resistance and extended tool life at elevated cutting speeds. A 47-degree variable helix geometry reduces harmonics and chatter, improving surface finish and chip evacuation. The tool weighs approximately 0.02 pounds and is built for use in CNC machining centers and manual mills requiring small-diameter, high-flute-count tooling.

This end mill is suited for finishing and semi-finishing passes in hardened steels, stainless alloys, and similar materials where heat buildup and vibration are primary concerns. The 5-flute configuration supports higher feed rates compared to standard 4-flute designs, making it a practical choice for production environments. The 1/8-inch shank diameter fits standard collets and tool holders commonly found in vertical machining centers and high-speed spindle setups. It is not centercutting and should not be used for plunge milling.

Key Features

• 3/32-inch cutting diameter with 0.0930-inch decimal equivalent for precise tool selection
• 5-flute design supports higher chip load and improved surface finish
• 47-degree variable helix reduces chatter and vibration during cut
• AlTiN coating for heat resistance and extended tool life in high-temperature alloys
• Solid carbide construction for rigidity and dimensional stability
• Right-hand cut and right-hand flute direction for standard CNC spindle use

Compatibility

Designed for use in standard 1/8-inch collets and ER-style tool holders on CNC machining centers and manual mills requiring small-diameter end mills.

Installation Notes

This tool should be installed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Use a calibrated torque wrench and the appropriate collet nut when seating the 1/8-inch shank to avoid runout. Because this end mill is not centercutting, avoid plunge entries — use ramping or helical interpolation to engage the workpiece.
