Harvey Tool 35493 Square End Mill 3/32 in 3 Flute Carbide

Product Description

The HARVEY TOOL 35493 is a solid carbide square end mill designed for precise milling operations in metalworking, moldmaking, and general machining applications. With a 3/32-inch (0.093-inch) cutting diameter and three flutes, this single-end tool delivers efficient chip evacuation and a clean square shoulder profile. The 30-degree helix angle balances cutting forces across the flute length, reducing chatter on light-duty passes. A bright, uncoated finish makes it well suited for non-ferrous metals and plastics where coating buildup is a concern. The extended-reach geometry provides access to recessed features without requiring a longer overall assembly.

This end mill fits CNC machining centers, manual mills, and high-speed spindle setups where small-diameter precision work is required. The 1/8-inch shank diameter is compatible with standard collet systems commonly found in both benchtop and production CNC equipment. It is typically installed by machinists and tool-and-die professionals working on intricate contours, slots, and pockets. The 0.139-inch length of cut and 1.125-inch reach length make it practical for shallow-to-moderate pocket depths in a single setup.

Key Features

• 3/32-inch (0.093-inch) cutting diameter for small-feature milling
• Three-flute geometry for improved chip flow and surface finish
• 30-degree helix angle reduces cutting forces and chatter
• Solid carbide construction for rigidity and wear resistance
• Center-cutting capable — plunge entry without pre-drilling required
• Extended reach at 1.125 inches for recessed pocket access
• Bright/uncoated finish suited for non-ferrous and plastic materials

Compatibility

Designed for use in standard 1/8-inch collet systems on CNC machining centers and manual milling machines requiring small-diameter solid carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's collet torque and runout specifications. Ensure the spindle is fully powered down and locked before changing tooling. Inspect the collet and tool holder for wear or debris before seating the shank to maintain concentricity. Verify that programmed feeds and speeds are appropriate for the workpiece material and this tool's diameter before running the first pass.
