Harvey Tool 12750 Square End Mill 0.05 in 3 Flute Carbide

Product Description

The HARVEY TOOL 12750 is a solid carbide square end mill designed for precision milling operations where tight tolerances and clean edge geometry are required. With a 0.0500-inch cutting diameter and three spiral flutes cut at a 30-degree helix angle, this tool delivers efficient chip evacuation and smooth surface finishes in ferrous and non-ferrous materials. The 0.3-inch length of cut and 2.5-inch overall length place it in the long-series category, giving machinists access to features with moderate depth requirements. It is center-cutting, allowing plunge and ramp entry without a pre-drilled pilot. Machining professionals in CNC shop environments are the primary users of this tool.

This end mill is suited for fine-detail work in industries such as aerospace, medical device manufacturing, mold making, and precision tooling. The 0.0500-inch diameter is appropriate for slot milling, profiling, and contouring in small-scale features where a larger tool cannot reach. The long-series geometry provides additional reach for stepped or recessed part features. The 0.125-inch shank diameter is compatible with standard collet and toolholder systems commonly found on CNC machining centers and high-speed spindles.

Key Features

• 0.0500-inch cutting diameter for fine-detail and small-feature milling
• 3 spiral flutes at 30-degree helix angle for efficient chip removal
• Center-cutting design allows direct plunge and ramp entry
• Solid carbide construction for rigidity and wear resistance
• Bright uncoated finish suitable for a wide range of workpiece materials
• Long-series length of cut at 0.3 inches provides extended reach capability

Compatibility

Designed for use in CNC machining centers and high-speed spindles accepting a 0.125-inch shank diameter via standard collet or toolholder systems.

Installation Notes

This tool should be installed and adjusted only by qualified machinists familiar with CNC tooling practices. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the end mill from the collet or toolholder. Verify runout and tool projection before initiating a cut, as small-diameter carbide tools are sensitive to misalignment and excessive overhang. Follow the tool manufacturer and machine builder recommendations for speeds, feeds, and depth of cut parameters for this diameter range.
