Harvey Tool 35508 Square End Mill 1/8 in 3 Flute Carbide

Product Description

The HARVEY TOOL 35508 is a solid carbide square end mill designed for precision milling in demanding shop environments. With a 0.125-inch cutting diameter and a 3/16-inch length of cut, this tool handles slotting, profiling, and contouring operations in a compact footprint. The 3-flute geometry balances chip evacuation and surface finish, making it well-suited for harder materials where rigidity and edge retention matter. A 30-degree helix angle promotes smooth cutting action and reduces cutting forces. Licensed machinists and CNC operators in job shops, toolrooms, and production environments are the primary users of this tool.

This end mill is built for use on CNC machining centers and manual knee mills where tight tolerances are required. The 0.125-inch shank diameter matches the cutting diameter, and the 3-inch overall length provides adequate clearance for most standard toolholding setups. The 1.5-inch reach length supports operations that require extended reach without sacrificing rigidity. Right-hand cut and right-hand flute configuration is standard for conventional CNC spindle rotation.

Key Features

• Solid carbide construction for superior rigidity and wear resistance compared to HSS
• 3-flute design balances chip clearance and surface finish in harder materials
• 30-degree helix angle reduces cutting forces and promotes smooth chip flow
• Centercutting geometry allows plunge milling operations
• Uncoated finish suitable for use with appropriate cutting fluids on a wide range of materials
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed for use in standard 1/8-inch collets, end mill holders, and shrink-fit toolholders on CNC machining centers and manual milling machines accepting a 0.125-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 an e-stop or powered-down state before changing tooling. Seat the shank to the recommended minimum insertion depth per the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning production cuts, as excessive runout accelerates edge wear on small-diameter carbide tools.
