Harvey Tool 890212-C6 Square End Mill 3/16 in 7 Flute Altin

Product Description

The HARVEY TOOL 890212-C6 is a 7-flute solid carbide square end mill designed for high-performance milling in ferrous and hardened materials. With a 3/16 inch cutting diameter and a 3/4 inch length of cut, this tool is built for finishing passes and detail work where surface finish and dimensional accuracy matter. The AlTiN coating provides oxidation resistance and thermal hardness at elevated cutting temperatures, extending tool life in demanding applications. The variable helix geometry reduces harmonic chatter, improving stability and consistency across the cut. This end mill is a single-end, right-hand cutting tool intended for use by machinists and tool-and-die professionals on CNC machining centers and manual mills.

This end mill is suited for use in job shops, production machining environments, and tool rooms where tight tolerances are required on steel, stainless steel, cast iron, and similar ferrous alloys. The 7-flute configuration increases chip load capacity and surface feet per minute potential compared to standard 4-flute designs, making it a strong choice for semi-finish and finish milling operations in harder workpiece materials where chip clearance is manageable.

Key Features

• 7-flute design increases material removal rate and surface finish quality in harder materials
• AlTiN coating improves heat resistance and wear life at elevated cutting temperatures
• Variable helix angle reduces chatter and harmonic vibration during the cut
• Solid carbide construction provides rigidity and dimensional stability
• Right-hand cut and right-hand flute orientation for standard CNC spindle compatibility
• Single-end configuration for direct replacement or toolchanger use

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 3/16 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Use a properly sized collet or end mill holder rated for 3/16 inch shank diameter and verify runout with a dial indicator before cutting. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
