Harvey Tool 73199 Square End Mill 1/4 Inch 4 Flute Carbide

Product Description

The HARVEY TOOL 73199 is a 4-flute, solid carbide square end mill designed for precision milling in ferrous and non-ferrous metals, plastics, and composites. With a 0.25-inch cutting diameter and a 0.75-inch length of cut, this single-end tool delivers clean, accurate results in slotting, profiling, and contouring operations. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish makes this end mill well suited for materials where coating adhesion is not required. Licensed machinists and CNC programmers working in job shops, tool rooms, and production environments are the primary users.

This end mill is built for use in vertical machining centers, CNC mills, and manual knee mills where tight tolerances are required. The 0.25-inch shank diameter fits standard ER collets and end mill holders. At 2.5 inches overall length, the 73199 is a compact, general-purpose tool appropriate for shallow-to-moderate depth-of-cut applications in both roughing and finishing passes when combined with appropriate feed and speed parameters for the material being machined.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting conditions
• 4 flutes for improved surface finish and feed rate capability compared to 2-flute designs
• 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Centercutting geometry allows plunge milling in addition to peripheral and slot cutting
• Right-hand cut and right-hand flute orientation compatible with standard CNC spindle rotation
• Bright, uncoated finish suitable for non-ferrous metals, plastics, and general-purpose work

Compatibility

Designed as a general-purpose square end mill compatible with any machining center or CNC mill equipped with a 0.25-inch collet, end mill holder, or equivalent toolholder accepting a 0.25-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Seat the shank fully in the collet or holder to the recommended insertion depth to prevent pullout under cutting loads. Verify runout with a dial indicator after tightening, and confirm feed and speed parameters are appropriate for the workpiece material before beginning the cut.
