Harvey Tool 67131 Square End Mill 1/32 in 5 Flute Carbide

Product Description

The HARVEY TOOL 67131 is a solid carbide square end mill designed for high-precision milling in demanding metalworking and machining applications. With a 1/32 inch (0.0310 inch) cutting diameter and a 1/4 inch length of cut, this tool is built for tight-tolerance work in small-scale features, slots, and profiles. The 5-flute geometry paired with a 50-degree variable helix promotes chip evacuation and reduces chatter at elevated feed rates. Right-hand cutting and right-hand flute direction are standard. This end mill is intended for use by machinists and toolroom technicians operating CNC mills and manual machines.

The 67131 is suited for finish milling, slotting, and contouring in small-part machining environments, including aerospace, medical device, and precision mold work where micro-scale features are common. The bright uncoated finish makes it appropriate for a range of ferrous and non-ferrous materials where coating interaction with the workpiece or cutting fluid is a consideration. The 1/8 inch shank diameter fits standard collets and toolholders used for miniature end mill work.

Key Features

• 1/32 inch (0.0310 inch) cutting diameter for micro-scale milling operations
• 5-flute design increases tool rigidity and surface finish quality
• Variable helix geometry reduces harmonic vibration and chatter
• Solid carbide construction delivers hardness and wear resistance
• Right-hand cut, right-hand flute direction for standard CNC spindle compatibility
• Bright uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC and manual milling machines equipped with 1/8 inch collets or toolholders accepting miniature end mills.

Installation Notes

Installation of miniature end mills should be performed by a qualified machinist. Ensure the spindle is fully powered down and at rest before changing tooling. Secure the 1/8 inch shank in a clean, properly sized collet or toolholder to the manufacturer-specified clamping torque range for the holder in use. Inspect the cutting edges under magnification before use, as micro-diameter carbide tools are susceptible to chipping during handling.
