Harvey Tool 994416-C4 Square End Mill 1/4 in 2 Flute Carbide

Product Description

The HARVEY TOOL 994416-C4 is a solid carbide square end mill designed for precision milling operations in demanding machining environments. With a 1/4 inch cutting diameter and 3/4 inch length of cut, this two-flute end mill delivers clean, accurate results in a compact form factor. The tool features an amorphous diamond coating that significantly increases surface hardness and reduces friction, extending tool life when cutting abrasive non-ferrous materials, composites, and plastics. At 2.5 inches overall length with a 1/4 inch shank diameter, it fits standard tool holders used in CNC machining centers and manual mills.

This end mill is suited for shops and machining professionals working with graphite, carbon fiber, fiberglass, plastics, and other abrasive non-metallic materials where conventional coatings wear rapidly. The right-hand cutting direction and right-hand flute spiral are standard for conventional CNC setups. The single-end configuration and centercutting capability allow for direct plunge entry as well as peripheral and slot milling. It is typically installed and operated by CNC machinists and toolroom technicians in both job shop and production environments.

Key Features

• Amorphous diamond coating for extended tool life in abrasive materials
• Solid carbide construction for rigidity and heat resistance
• Centercutting design allows direct plunge milling
• Two-flute geometry supports chip clearance in softer and composite materials
• Compression flute type for reduced delamination risk in layered materials
• Right-hand cut and right-hand helix for standard CNC compatibility

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 1/4 inch tool holders and collets used in CNC machining centers and conventional milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Torque set screws or collet nuts to the tool holder manufacturer specifications. Confirm runout with a dial indicator before beginning a production cut to protect both the tool and the workpiece.
