Harvey Tool 834178 Square End Mill 5/64 in 4 Flute Carbide

Product Description

The HARVEY TOOL 834178 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 5/64 inch (0.0780 inch) cutting diameter and a 13/32 inch (0.406 inch) length of cut, this tool handles slotting, profiling, and finishing passes in tight-tolerance work. Four flutes and a 30-degree helix angle provide a balance of chip evacuation and surface finish quality. The bright, uncoated finish makes it suitable for a range of workpiece materials where coating is not required. Machinists and CNC operators install this tool in standard collet or end mill holders.

This end mill fits residential and commercial machine shop environments, as well as production and tool-and-die settings. The 1/8 inch shank diameter suits smaller spindle toolholders and collet chucks commonly found on CNC mills, manual knee mills, and benchtop machining centers. Its compact geometry makes it well suited for fine-detail work, small-feature milling, and finishing cuts where a larger diameter tool cannot reach. Right-hand cutting and right-hand flute direction are standard for conventional CNC and manual milling setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• 5/64 inch cutting diameter (0.0780 inch) for fine-feature and small-slot applications
• 4-flute, 30-degree helix design balances chip flow and surface finish
• Center-cutting capability allows direct plunge entry into workpieces
• Right-hand cut and right-hand flute direction for standard CNC setups
• Bright, uncoated finish suitable for applications where coatings are not required

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 1/8 inch collet or end mill holder tooling systems used in CNC and manual milling operations.

Installation Notes

Installation is performed by machinists or CNC operators using standard end mill holders or collet chucks rated for the 1/8 inch shank diameter. Ensure the spindle is fully powered down and at a complete stop before inserting or removing the tool. Verify holder runout and torque the retention mechanism to the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use, as solid carbide tools are brittle and should not be used if the edge is compromised.
