Harvey Tool 74125 Ball End Mill 1/8 in 2 Flute Carbide

Product Description

The HARVEY TOOL 74125 is a miniature solid carbide ball end mill designed for precision milling in tight-tolerance applications. With a 1/8-inch cutting diameter and a 3/8-inch length of cut, this single-end tool runs a 2-flute, right-hand spiral configuration with a 30-degree helix angle. The bright, uncoated carbide construction makes it well-suited for both roughing and finishing passes. At 1.5 inches overall length with a 0.0625-inch nose radius, it fits standard 1/8-inch straight-cylindrical shank collets. Licensed machinists, tool and die makers, and CNC programmers will find it a reliable choice for small-feature milling.

This end mill is rated for use on steel, stainless steel, cast iron, and non-ferrous metals, covering a wide range of common shop materials. The stub and standard series designation makes it a practical pick for shallow pocket, slot, and contour work where a compact tool profile is needed to maintain rigidity and reduce deflection. It is equally applicable in job shop environments and production CNC setups running small-diameter features.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 1/8-inch cutting diameter with a 0.0625-inch nose radius for fine-detail ball-end profiling
• 30-degree right-hand helix promotes chip evacuation and smooth cutting action
• 2-flute geometry supports both roughing and finishing in a single tool
• Bright, uncoated finish compatible with a wide range of cutting fluids and materials
• Straight-cylindrical 1/8-inch shank fits standard collet chucks without adapters

Compatibility

Designed for use on steel, stainless steel, cast iron, and non-ferrous metals. Fits any CNC machining center or manual mill equipped with a 1/8-inch straight-collet or ER-style collet chuck. Part of the HARVEY TOOL Miniature End Mills Ball Stub and Standard series.

Installation Notes

Install in a clean, properly sized collet and torque the collet nut to the spindle manufacturer specification before cutting. Verify runout with a dial indicator before production use, as excessive runout accelerates wear on small-diameter carbide tools. Never exceed the recommended depth of cut or feed rate for the workpiece material and machine rigidity class. Handle carbide end mills carefully to avoid chipping the cutting edges prior to use.
