Harvey Tool 53408-C6 Square End Mill 1/8 in 5 Flute Altin

Product Description

The HARVEY TOOL 53408-C6 is a solid carbide square end mill designed for high-performance milling in demanding materials. It features a 1/8 inch diameter with a 1 inch length of cut and a 5-flute geometry built around a variable helix design. The variable helix reduces harmonic chatter during cut, improving surface finish and tool life. With an AlTiN coating, the tool handles elevated cutting temperatures and resists wear in ferrous and hardened materials. At 2.5 inches overall length and a 1/8 inch shank diameter, it fits standard collet and toolholder setups used by machinists in production and job shop environments.

This end mill is suited for profiling, slotting, and finishing passes in steel, stainless steel, titanium, and other hard alloys. The 5-flute configuration delivers higher feed rates compared to standard 4-flute tools, making it effective in high-speed machining programs. Right-hand cut and right-hand flute direction follow conventional CNC milling setups. It is a single-end tool intended for machining centers, vertical mills, and CNC routers where tight tolerances and consistent finish are required.

Key Features

• 1/8 inch diameter with 1 inch length of cut for deep-reach profiling in confined slots
• 5-flute geometry allows higher feed rates and improved surface finish versus 4-flute designs
• Variable helix angle reduces chatter and vibration during aggressive cuts
• AlTiN coating provides heat resistance and extended tool life in ferrous and hardened materials
• Solid carbide construction maintains rigidity and dimensional stability at high RPM
• Right-hand cut, right-hand helix matches standard CNC milling spindle direction

Compatibility

Designed as a direct-fit replacement for 1/8 inch shank square end mills in standard ER collets, end mill holders, and shrink-fit toolholders on CNC machining centers and manual vertical mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Confirm spindle is fully stopped and machine is in an e-stop or lockout state before changing tooling. Seat the shank fully in the collet or holder to the recommended gauge length and torque the retention nut per the toolholder manufacturer specification. Verify runout at the tool tip with a dial indicator before beginning a cut program.
