Harvey Tool 35012-C3 Square End Mill 3/16 in 4 Flute Carbide

Product Description

The HARVEY TOOL 35012-C3 is a solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. With a 3/16 inch cutting diameter and a 2-1/4 inch length of cut, this tool delivers extended reach capability for deep-pocket and slotting operations. The 4-flute, right-hand cutting geometry with a 30-degree helix angle provides efficient chip evacuation and a smooth surface finish. An AlTiN (aluminum titanium nitride) coating improves wear resistance and thermal hardness at elevated cutting temperatures, extending tool life in ferrous and hardened materials. Installed and operated by machinists and CNC programmers in job shop and production environments.

This end mill is suited for milling steel, stainless steel, cast iron, and similar hard materials where heat generation is a primary concern. The 2-1/4 inch length of cut places it in the long-reach category, making it appropriate for deep-cavity work, tall-wall contouring, and applications where standard-length tools cannot reach. The centercutting design allows plunge entry. The 3/16 inch shank diameter matches the cutting diameter, so standard 3/16 inch collets or tool holders apply. Single-end configuration means the tool is replaced rather than indexed when worn.

Key Features

• 3/16 inch cutting diameter with matching 3/16 inch shank for direct collet holding
• 2-1/4 inch length of cut for deep-pocket and extended-reach milling
• 4-flute, right-hand cut and right-hand flute geometry for efficient material removal
• 30-degree helix angle promotes smooth cutting action and chip flow
• AlTiN coating enhances hardness and oxidation resistance at high operating temperatures
• Centercutting design permits direct plunge entry without pre-drilling

Compatibility

Designed as an OEM-style solid carbide square end mill for use in CNC machining centers and manual mills equipped with standard 3/16 inch collets or end mill holders.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and de-energize the spindle completely before changing tooling. Seat the shank fully into a clean, undamaged collet or end mill holder and torque the retention mechanism per the tool holder manufacturer specification. Inspect the AlTiN coating and cutting edges for chips or wear before each use, and do not use a damaged tool.
