Harvey Tool 826847 Square End Mill 3/64 in 4 Flute Carbide

Product Description

The HARVEY TOOL 826847 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 3/64 inch (0.0470 inch) cutting diameter and a 3/8 inch length of cut, this tool is built for tight-tolerance work in small-bore and detail milling applications. The 4-flute configuration provides a balance of chip evacuation and surface finish quality. A 30-degree helix angle promotes smooth cutting action and reduces chatter. This end mill is single-end and bright/uncoated, making it suitable for use in a range of materials without coating-related thermal considerations. Machinists and CNC operators in job shops and production environments are the primary users.

This end mill is suited for finish milling, slotting, and profiling in small-scale or precision machining applications. The 1/8 inch shank diameter makes it compatible with standard collets and tool holders used in CNC machining centers and manual mills. Its compact geometry targets fine-detail work where larger tools cannot reach. Right-hand cutting and right-hand flute direction are standard configurations for conventional CNC spindle setups. The 2-1/2 inch overall length provides adequate reach without sacrificing rigidity at this diameter.

Key Features

• 3/64 inch (0.0470 inch) cutting diameter for fine-detail and small-bore milling
• 4 flutes for improved surface finish and balanced chip load
• 30-degree helix angle reduces cutting forces and chatter
• Solid carbide construction for rigidity and wear resistance
• Bright/uncoated finish for broad material compatibility
• Center-cutting capable, allowing plunge entry
• Right-hand cut and right-hand flute direction for standard CNC spindle use

Compatibility

Designed for use in standard 1/8 inch collets and tool holders on CNC machining centers and manual mills configured for right-hand cutting tools.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading tooling. Seat the shank fully in the collet to the recommended grip length before tightening to avoid runout. At 3/64 inch diameter, this tool is highly susceptible to breakage from improper feeds, speeds, or excessive overhang beyond the collet face.
