Harvey Tool 34639 Square End Mill 1mm 3 Flute Carbide

Product Description

The HARVEY TOOL 34639 is a solid carbide square end mill designed for precision milling in demanding machining applications. With a 1 mm cutting diameter and a 1.5 mm length of cut, this tool is built for small-feature work where tight tolerances are required. The 3-flute geometry with a 30-degree helix angle balances chip evacuation with surface finish quality. At 2.5 inches overall length with a 0.125-inch shank diameter, it mounts in standard collet toolholders. Centercutting capability allows both plunge and lateral cutting passes. Machinists and CNC operators working in mold, die, medical device, and aerospace environments are the primary installers and users of this tool.

This end mill is suited for finish and semi-finish milling of small slots, pockets, and contoured surfaces in ferrous and non-ferrous materials. The bright uncoated carbide substrate performs well in aluminum, brass, copper, and similar non-ferrous workpieces where coating interaction is a concern. The extended reach design, with a 0.325-inch reach length, provides clearance for deeper cavity work without sacrificing rigidity. Right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups.

Key Features

• 1 mm cutting diameter with 1.5 mm length of cut for small-feature precision work
• 3-flute solid carbide construction for rigidity and wear resistance
• 30-degree helix angle balances chip flow and surface finish
• Centercutting design allows direct plunge entry into workpiece
• Extended reach at 0.325 inches for deep cavity and pocket clearance
• Bright uncoated finish suited for non-ferrous and non-reactive material applications

Compatibility

Designed for use in standard 0.125-inch (1/8-inch) collet toolholders on CNC milling machines and machining centers requiring a right-hand, single-end square profile end mill with a 1 mm cutting diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 0.125-inch shank fully into the collet and torque the collet nut to the toolholder manufacturer specification. At 1 mm diameter, tool runout must be minimized — verify runout with a dial indicator before cutting to prevent premature tool breakage.
