Harvey Tool 834205-C3 Square End Mill 3mm 4-flute Altin

Product Description

The HARVEY TOOL 834205-C3 is a single-end, square-profile solid carbide end mill designed for high-performance milling in ferrous and non-ferrous materials. The tool carries a 3 mm (0.1180 inch) cutting diameter with a 5/8-inch length of cut and a 30-degree helix angle that promotes efficient chip evacuation and smooth cutting action. Four flutes deliver a balance of chip load capacity and surface finish quality. The AlTiN coating adds thermal resistance, making this end mill well suited for dry or semi-dry machining environments where heat generation is a concern. The 1/8-inch shank fits standard collets and tool holders for small-diameter work.

This end mill is used in CNC machining centers and manual mills for slotting, profiling, and peripheral milling operations on ferrous alloys, stainless steel, cast iron, and hardened materials. The solid carbide construction and AlTiN coating make it appropriate for production environments where tool life and consistent dimensional accuracy are priorities. The small cutting diameter suits detail work, tight-tolerance features, and die or mold applications. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling on vertical and horizontal machining centers.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN coating provides high-temperature oxidation resistance for dry or semi-dry machining
• 4-flute geometry balances chip evacuation with finish quality
• 30-degree helix angle reduces cutting forces and promotes smooth chip flow
• Center-cutting design allows plunge entry as well as peripheral and slot milling
• Right-hand cut and right-hand flute direction for standard CNC and manual setups

Compatibility

Fits any tool holder or collet accepting a 1/8-inch shank diameter. Designed for use in CNC machining centers, vertical mills, and similar equipment where small-diameter solid carbide end mills are specified.

Installation Notes

Installation is performed by machinists and CNC programmers. Ensure the tool holder or collet is clean and free of chips before seating the shank to full engagement depth. Torque the collet nut to the tool holder manufacturer specification. Verify runout with a dial indicator before running production cuts, as excessive runout accelerates tool wear on small-diameter carbide tools.
