Harvey Tool 942247-C8 Square End Mill 3/64 in 3 Flute Carbide

Product Description

The HARVEY TOOL 942247-C8 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 3/64 inch (0.047 inch) cutting diameter and a 9/64 inch (0.141 inch) length of cut, this tool is built for small-feature work requiring tight tolerances. Three flutes and a variable 42-degree helix angle improve chip evacuation and reduce chatter during operation. A titanium diboride (TiB2) coating increases surface hardness and wear resistance. Machinists and tooling professionals working with CNC milling centers install this end mill for fine detail passes and micro-milling applications.

This end mill is suited for use in vertical and horizontal CNC machining centers where small-diameter tooling is required. The 1/8 inch shank diameter fits standard collets and tool holders common in production and prototype shops. The single-end, right-hand cutting and right-hand flute configuration makes it a direct fit for conventional right-hand spindle setups. It is appropriate for milling aluminum, plastics, copper alloys, and other non-ferrous or softer materials where TiB2 coating delivers optimal performance. Overall length of 1-1/2 inches keeps deflection minimal at this diameter.

Key Features

• 3/64 inch (0.047 inch) cutting diameter for small-feature and micro-milling applications
• Solid carbide construction for rigidity and extended tool life
• Titanium diboride (TiB2) coating for enhanced wear resistance and surface hardness
• Variable helix design reduces harmonic vibration and chatter
• Center-cutting capable — supports plunge entry cuts
• Right-hand cut, right-hand flute — compatible with standard CNC spindle direction

Compatibility

Designed for use in CNC milling machines equipped with 1/8 inch collets or tool holders. Compatible with right-hand spindle configurations standard in vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Seat the 1/8 inch shank fully and evenly in the collet and torque the collet nut to the tool holder manufacturer's specification. At this diameter, minimize runout during setup — even small amounts of runout cause accelerated tool wear and breakage.
