Harvey Tool 34647-C3 Square End Mill 3/64 Inch 3 Flute

Product Description

The HARVEY TOOL 34647-C3 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 3/64 inch (0.047 inch) cutting diameter and a 1/8 inch shank, this tool is built for small-feature work where rigidity and accuracy matter. The AlTiN coating provides heat resistance and extended tool life in ferrous and high-hardness materials. Three flutes with a 30-degree helix angle improve chip evacuation and surface finish. Centercutting geometry allows plunge entry, giving the machinist more flexibility in toolpath strategy. Licensed machinists and CNC operators in production and prototype shops are the primary users of this tool.

This end mill suits applications requiring fine detail work, such as slotting, profiling, and pocketing in small-scale components. The 0.071 inch length of cut and 0.375 inch reach length make it appropriate for shallow features with controlled radial engagement. It is well suited for use on CNC machining centers and high-speed spindle setups where small-diameter tooling is required. The right-hand cut and right-hand flute configuration is standard for conventional CNC milling setups.

Key Features

• 3/64 inch (0.047 inch) cutting diameter for small-feature precision milling
• Solid carbide construction for rigidity and wear resistance
• AlTiN finish for heat resistance and extended tool life in hard materials
• 3 flutes with 30-degree helix for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Right-hand cut and right-hand flute, standard CNC orientation

Compatibility

Designed as a standard 1/8 inch shank square end mill compatible with CNC machining centers, vertical mills, and high-speed spindle collet systems that accept 1/8 inch straight shanks.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or tool holder to the recommended engagement depth before tightening. Verify runout with a dial indicator after installation, as small-diameter carbide tooling is sensitive to excessive runout that can cause premature breakage.
