Harvey Tool 34662 Square End Mill 1/16 in 3 Flute Carbide

Product Description

The HARVEY TOOL 34662 is a solid carbide square end mill designed for precise milling in demanding materials. It features a 1/16 inch cutting diameter, a 3/32 inch length of cut, and a 1/8 inch shank diameter with an overall length of 2.5 inches. The three-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The long-reach, stub-flute geometry provides access to confined features while maintaining rigidity. This tool is centercutting and ships uncoated, making it well suited for machinists and tool-and-die professionals working in precision machining environments.

This end mill is intended for single-end use in a wide range of workpiece materials, including steel, stainless steel, cast iron, aluminum and other non-ferrous metals, and carbon fiber reinforced polymer (CFRP) materials. Its long-reach configuration — with a 1/2 inch reach length — makes it a practical choice for slotting, profiling, and pocketing operations where a standard-length tool cannot reach the feature. It is suited for CNC machining centers and high-speed spindle applications requiring tight-tolerance, small-diameter work.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 1/16 inch cutting diameter with 3/32 inch length of cut for fine-feature machining
• Three right-hand flutes with 30-degree helix angle for efficient chip evacuation
• Long-reach, stub-flute series with 1/2 inch reach length for access to deep or confined features
• Centercutting geometry allows plunge entry
• Bright/uncoated finish suitable for use with or without coolant on compatible materials

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 1/8 inch shank. Rated for steel, stainless steel, cast iron, aluminum and non-ferrous metals, and CFRP materials per the manufacturer workpiece material classification.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians using a collet or end mill holder rated for 1/8 inch shank diameter. Verify spindle runout before seating the tool, as runout at this diameter will directly affect tool life and cut quality. Do not exceed the manufacturer-rated depth of cut for the given workpiece material. Ensure the machine spindle is fully stopped and the control is in a safe state before changing or measuring the tool.
