Harvey Tool 33708-C4 Square End Mill 0.125in 3 Flute Carbide

Product Description

The HARVEY TOOL 33708-C4 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.125-inch cutting diameter and a 1-inch length of cut, this tool handles slotting, profiling, and contouring in tight-tolerance applications. The 3-flute geometry with a 30-degree helix angle balances chip evacuation with surface finish quality. An amorphous diamond coating reduces friction and extends tool life when cutting abrasive or non-ferrous materials. This end mill is installed and operated by machinists and CNC programmers working in job shop, production, or toolroom settings.

This end mill suits applications requiring a small-diameter, high-rigidity cutting tool in CNC milling machines and manual mills. The 0.125-inch shank diameter matches standard collet and end mill holder sizes used with ER-style tooling systems. The 2.5-inch overall length provides adequate reach for most standard fixturing setups without sacrificing rigidity. Right-hand cut and right-hand flute direction make this tool compatible with conventional spindle-forward CNC programming. Center-cutting capability allows plunge entry directly into the workpiece.

Key Features

• 0.125-inch cutting diameter with 1-inch length of cut for precise, small-feature milling
• 3-flute, 30-degree helix design balances chip clearance and surface finish
• Amorphous diamond coating for reduced friction and extended tool life on abrasive materials
• Center-cutting geometry supports direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute direction for standard CNC spindle operation
• Solid carbide construction delivers rigidity and wear resistance in demanding cuts

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 0.125-inch collets or end mill holders; suitable for non-ferrous metals, plastics, and other materials compatible with amorphous diamond-coated tooling.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an safe state before loading or unloading the tool. Seat the shank fully in the collet or holder and torque to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a production run, as runout beyond acceptable limits will reduce tool life and surface finish quality on a small-diameter end mill.
