Harvey Tool 874193-C3 Square End Mill 3/32 in 4 Flute Altin

Product Description

The HARVEY TOOL 874193-C3 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. With a 3/32 inch (0.093 inch) cutting diameter, 4-flute geometry, and a 30-degree right-hand helix, this end mill delivers efficient chip evacuation and clean finishes on ferrous and non-ferrous materials. The AlTiN coating adds thermal resistance, extending tool life in high-speed and dry-cutting operations. Overall length is 2.5 inches with a 1/8 inch shank diameter. It ships as a single-end tool and is intended for use by machinists and toolroom professionals working on CNC mills and manual vertical mills.

This end mill suits close-tolerance profiling, slotting, and peripheral milling in tool steels, hardened steels, stainless, and aluminum alloys. The extended reach configuration with a 0.75 inch reach length allows access to deeper features without tool interference. Length of cut is 0.139 inch, within the rated range of 0.100 to 0.200 inch, making it appropriate for shallow-depth finish passes and fine detail work in production and prototype environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides high-temperature oxidation resistance for dry and high-speed cutting
• 4-flute, right-hand cut and right-hand flute geometry for smooth finish passes
• 30-degree helix angle supports efficient chip flow and reduced cutting force
• Extended reach design with 0.75 inch reach length for deeper feature access
• Single-end configuration; not centercutting — not suited for direct plunge entry

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard 1/8 inch collet or end mill holder setups on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC or manual milling equipment. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1/8 inch shank fully into a clean, properly sized collet or end mill holder and torque the retention hardware per the holder manufacturer specification. Because this tool is not centercutting, avoid direct axial plunge cuts — use ramping or helical entry strategies instead.
