Harvey Tool 854808-C6 Square End Mill 1/8 in 7 Flute Carbide

Product Description

The HARVEY TOOL 854808-C6 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. With a 0.125 inch cutting diameter and 7 flutes, this tool delivers high material removal rates and excellent surface finishes. The AlTiN coating provides heat resistance and extended tool life in ferrous and hardened materials. A 20-degree variable helix angle reduces harmonic vibration during cuts, improving stability and finish quality. This end mill is a single-end tool with right-hand cut and right-hand flute orientation, suited for CNC machining centers and manual mills operated by machinists and tooling professionals.

This end mill is used in precision machining environments where tight tolerances and fine finishes are required. It is well suited for profiling, slotting, and peripheral milling in ferrous alloys, stainless steel, and hardened materials. The 3/8 inch length of cut and 1/4 inch shank diameter make it a practical choice for short-reach finishing passes and detail work in tight pockets. This tool is not center-cutting, so it is not intended for direct plunge operations without a pre-drilled entry point.

Key Features

• 7-flute geometry increases chip load per tooth and improves finish quality at higher feed rates
• AlTiN coating enhances heat resistance and reduces tool wear in ferrous and hardened materials
• 20-degree variable helix reduces chatter and harmonic vibration during profiling cuts
• Solid carbide construction provides rigidity and dimensional stability under load
• Right-hand cut, right-hand flute configuration for standard CNC spindle direction
• Single-end design with 1/4 inch shank for use in standard collets and end mill holders

Compatibility

Designed as a direct-fit replacement end mill for CNC machining centers and manual mills accepting a 1/4 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended engagement depth before tightening. Because this tool is not center-cutting, avoid direct plunge entries without a pre-drilled or ramped entry path.
