Harvey Tool 934908 Square End Mill 1/8 in 3 Flute Carbide

Product Description

The HARVEY TOOL 934908 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 1/8 inch (0.1250 inch) mill diameter and three flutes, it delivers clean cuts and efficient chip evacuation in ferrous and non-ferrous materials. The 30-degree helix angle balances cutting aggressiveness with finish quality. Centercutting geometry allows for plunge milling operations in addition to standard peripheral and slot milling. This tool is intended for use by machinists and tool-and-die professionals running CNC mills and manual milling machines where tight tolerances and small-diameter work are required.

This end mill is suited for small-feature milling, slotting, profiling, and contouring in tight-clearance areas. The 3/16 inch length of cut and 7/8 inch reach length make it appropriate for shallow pockets and detail work on small components. The bright, uncoated finish makes it a general-purpose option across a range of base materials. Extended reach geometry adds flexibility for accessing recessed features without sacrificing rigidity at this diameter.

Key Features

• Solid carbide construction for rigidity and wear resistance at small diameters
• Three-flute design balances chip clearance with surface finish
• 30-degree right-hand helix for efficient cutting action
• Centercutting capable — supports plunge entry without a pre-drilled pilot hole
• Extended reach at 7/8 inch for accessing recessed or deep features
• Bright/uncoated finish suitable for general-purpose use across multiple materials

Compatibility

Designed as a general-purpose small-diameter square end mill for CNC and manual milling machines accepting a 1/8 inch shank diameter collet or chuck.

Installation Notes

Installation should be performed by a qualified machinist familiar with toolholder runout tolerances and collet maintenance. Ensure the milling machine spindle is fully powered down and locked before changing tooling. Secure the 1/8 inch shank fully within the collet or chuck to the manufacturer-recommended engagement depth to prevent pullout. At this diameter, minimize tool overhang and verify runout before cutting to reduce the risk of tool breakage.
