Harvey Tool 956847-C3 Square End Mill 3/64 in 4 Flute

Product Description

The HARVEY TOOL 956847-C3 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 3/64 inch (0.0470 inch) cutting diameter and four flutes, this single-end tool delivers clean, accurate cuts in hardened and abrasive materials. The AlTiN coating adds thermal resistance and surface hardness, extending tool life when running at elevated speeds or in dry cutting conditions. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This end mill is center-cutting, allowing plunge entry, and features an extended reach configuration suited for accessing recessed features or deep pockets in a workpiece.

This end mill is intended for use in CNC milling operations where tight tolerances and fine detail work are required. The 3/64 inch diameter makes it well suited for micro-milling applications in tool-and-die, mold making, aerospace component machining, and precision medical part manufacturing. The 1/8 inch shank diameter is compatible with standard collets found on vertical and horizontal machining centers. The extended reach geometry, with a 1/4 inch reach length, allows the tool to machine features that standard-reach end mills cannot access.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides thermal protection and extends tool life in high-speed or dry cutting
• Four right-hand flutes with right-hand cutting direction for conventional milling setups
• 30-degree helix angle supports efficient chip evacuation and reduced cutting force
• Center-cutting design permits direct plunge entry into workpiece material
• Extended reach with 1/4 inch reach length for access to recessed or deep features

Compatibility

Designed for use in CNC machining centers equipped with 1/8 inch collets or tool holders accepting standard shank diameters in the 0.1250 inch range.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully powered down and locked out before inserting or removing the end mill from the tool holder. Seat the shank fully into the collet and torque the collet nut to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning production cuts, as excessive runout on a micro-diameter tool can cause premature breakage.
