Harvey Tool 50308-C4 Square End Mill 1/8 in 4 Flute Carbide

Product Description

The HARVEY TOOL 50308-C4 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 1/8 inch cutting diameter and 4-flute geometry, it delivers clean, accurate cuts in ferrous and non-ferrous materials. The amorphous diamond finish reduces friction and extends tool life compared to uncoated carbide. At 3/16 inch length of cut and 1-1/2 inch overall length, this end mill is suited for tight-tolerance work in shallow pockets, slots, and profiles. It is installed and operated by CNC machinists and toolroom professionals working on vertical and horizontal machining centers.

This end mill is appropriate for high-precision milling applications across aerospace, medical device, mold and die, and general machining industries. The 30-degree helix angle promotes chip evacuation and reduces cutting forces in both light finishing and moderate material removal passes. The centercutting design allows plunge entry directly into the workpiece without a pre-drilled pilot hole, adding setup flexibility. Right-hand cut and right-hand flute orientation conform to standard CNC spindle configurations used in most production and toolroom environments.

Key Features

• 1/8 inch cutting diameter with 3/16 inch length of cut for shallow slot and pocket milling
• 4-flute solid carbide construction for rigidity and edge retention
• Amorphous diamond finish reduces friction and extends tool life
• 30-degree helix angle promotes efficient chip evacuation
• Centercutting geometry allows direct plunge entry without a pilot hole
• Right-hand cut, right-hand flute - compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style solid carbide square end mill suitable for use in standard CNC machining centers and manual mills equipped with 1/8 inch collet or tool holder systems.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully within the collet or end mill holder to the minimum recommended insertion depth before tightening. Verify spindle runout prior to operation, as excessive runout will accelerate edge wear on small-diameter carbide tooling. Never exceed the tool manufacturer's recommended feed and speed parameters for the specific workpiece material.
