Harvey Tool 33714 Square End Mill 7/32 Inch 4 Flute Carbide

Product Description

The HARVEY TOOL 33714 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineering plastics. With a 7/32-inch (0.2187-inch) cutting diameter and four flutes, this centercutting tool handles slotting, profiling, and plunge cutting in a single setup. The 30-degree helix angle balances chip evacuation and surface finish across a range of materials. Right-hand cut and right-hand flute geometry follow standard milling conventions, making this a direct fit for most CNC machining centers and manual knee mills. Machinists and toolroom technicians install this style of end mill for close-tolerance work where consistent tool geometry is critical.

This end mill suits light-to-medium-duty milling in job shops, production machining, and maintenance toolrooms. The 1-3/4-inch length of cut accommodates wall heights and slot depths common in fixture work and prototype machining. The 1/4-inch shank diameter fits standard ER collets, end mill holders, and set-screw tool holders commonly found in 3-axis and 4-axis CNC setups. Its uncoated carbide construction makes it well suited for non-ferrous metals, aluminum alloys, plastics, and certain steel applications where a bare carbide edge is preferred for edge sharpness and re-grindability.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• Four-flute design balances material removal rate with chip clearance
• 30-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Right-hand cut, right-hand flute — standard orientation for conventional and climb milling
• Uncoated finish preserves a sharp edge and simplifies re-grinding

Compatibility

Designed for use in CNC machining centers, manual mills, and multi-axis machines equipped with 1/4-inch collets or end mill holders. Compatible with standard ER16, ER20, and similarly sized collet systems that accept a 0.2500-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 powered down or in an e-stop state before changing tooling. Seat the shank to the full recommended engagement depth in the tool holder to minimize runout and prevent pull-out under load. Verify tool runout with a dial indicator before production cutting, especially for close-tolerance applications.
