Harvey Tool 894308 Square End Mill 1/8 in 3 Flute Carbide

Product Description

The HARVEY TOOL 894308 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 1/8 inch cutting diameter and a 3/4 inch length of cut, this tool handles slotting, profiling, and peripheral milling in tight-tolerance applications. The 3-flute geometry balances chip evacuation and cutting efficiency, making it well suited for ferrous and non-ferrous materials. A 30-degree helix angle promotes smooth cutting action and reduced chatter. This end mill is installed and operated by machinists and CNC tooling professionals in shop and production environments.

This end mill fits standard 1/8 inch collets and tool holders, making it compatible with CNC machining centers, manual mills, and high-speed spindle setups where a compact cutting tool is required. The 2-1/2 inch overall length provides adequate reach for most standard milling applications. Right-hand cutting and right-hand flute direction are the conventional configuration for general-purpose milling. The centercutting capability allows plunge cutting as well as conventional contouring passes.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• 3-flute design balances chip clearance with surface finish quality
• 30-degree helix angle reduces cutting forces and chatter
• Centercutting geometry enables plunge entry without a pilot hole
• Bright/uncoated finish suitable for use with cutting fluids or dry in non-ferrous materials
• Right-hand cut, right-hand flute — standard configuration for most CNC and manual mill setups

Compatibility

Designed for use in standard 1/8 inch collets and tool holders on CNC machining centers and manual milling machines requiring a compact square end mill profile.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or end mill holder to the recommended engagement depth and verify runout with a dial indicator before beginning a cut. Do not exceed the rated speeds and feeds for solid carbide tooling in the material being machined.
