Harvey Tool 823102 Square End Mill 7/64 in 3 Flute Carbide

Product Description

The HARVEY TOOL 823102 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 7/64 inch (0.109 inch decimal) cutting diameter and a 0.164 inch length of cut, making it well suited for tight-tolerance slotting, profiling, and peripheral milling in small-feature work. The 3-flute geometry balances chip evacuation with rigidity, and the 30-degree helix angle promotes smooth cutting action. The bright, uncoated finish is appropriate for a wide range of workpiece materials. This end mill is a single-end tool and is center-cutting, allowing plunge entry. Installation and use require a compatible collet or end mill holder sized to the 1/8 inch shank diameter.

This end mill is used in CNC machining centers, manual mills, and high-speed spindle applications where small-diameter tooling is required. It is commonly selected for detail work in mold making, die work, aerospace components, and precision mechanical parts. The compact 1.5 inch overall length and 1/8 inch shank diameter make it compatible with standard ER collet systems and small-bore tool holders. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling setups on most machine tool platforms.

Key Features

• 7/64 inch (0.109 inch) cutting diameter for small-feature precision work
• 3-flute design for balanced chip load and surface finish
• 30-degree helix angle for smooth, efficient cutting action
• Solid carbide construction for rigidity and wear resistance
• Center-cutting geometry allows direct plunge entry
• Bright/uncoated finish suitable for a broad range of materials
• Right-hand cut and right-hand flute direction for standard machine setups

Compatibility

Designed for use with standard 1/8 inch collets and end mill holders on CNC machining centers and manual milling machines. No specific compatible model numbers were provided by the manufacturer for this part.

Installation Notes

This end mill is installed by a machinist or CNC operator using a compatible collet or shrink-fit holder sized to the 1/8 inch shank. Confirm runout and tool projection before beginning a cut, as small-diameter carbide tooling is sensitive to excessive overhang and vibration. Power down and lock out the spindle before changing tooling. Follow the machine manufacturer guidelines and applicable shop safety standards for tool change procedures.
