Harvey Tool 63510-C6 Square End Mill 5/32 in 5 Flute Carbide

Product Description

The HARVEY TOOL 63510-C6 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. With a 5/32-inch (0.1562-inch) cutting diameter and five variable-helix flutes, this tool delivers improved chip evacuation and reduced chatter compared to fixed-helix designs. The AlTiN coating increases surface hardness and heat resistance, making it well-suited for dry or semi-dry cutting of hardened steels, stainless, and high-temperature alloys. Machinists and CNC operators working in tool rooms, job shops, and production environments rely on this end mill for fine-feature profiling and slotting where tight tolerances are required.

This end mill is intended for use in CNC machining centers and manual knee mills capable of holding a 3/16-inch shank. It is a single-end, right-hand cut, right-hand helix tool with a 7/8-inch length of cut and a 3-inch overall length. The non-centercutting geometry means it is not suited for direct plunge operations and should be entered via ramp or helical interpolation. It fits applications in aerospace, medical, and mold-and-die work where small-diameter, multi-flute tooling is standard practice.

Key Features

• 5-flute variable helix design reduces harmonic vibration during high-speed milling
• AlTiN coating provides elevated heat resistance and extended tool life in ferrous and exotic materials
• Solid carbide construction offers superior rigidity and wear resistance compared to HSS tooling
• Right-hand cut and right-hand flute direction for use in standard CNC spindle configurations
• 3/16-inch shank diameter fits common collet and end mill holder systems
• Non-centercutting geometry requires ramp or helical entry rather than direct plunge

Compatibility

Designed as an OEM-style solid carbide square end mill for use in CNC machining centers and milling machines equipped with a 3/16-inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or holder is torqued to the machine manufacturer's specification before running. Inspect the cutting edges and coating condition before each use and replace the tool at the first sign of chipping or excessive wear to avoid workpiece damage.
