Harvey Tool 930825 Square End Mill 0.025 in 3 Flute Carbide

Product Description

The HARVEY TOOL 930825 is a solid carbide square end mill designed for high-precision milling in tight-tolerance applications. With a 0.025-inch cutting diameter and a 0.038-inch length of cut, this tool is built for micro-milling work where dimensional accuracy is critical. The 3-flute geometry with a 42-degree variable helix promotes chip evacuation and reduces chatter during cut. The bright uncoated finish suits bare carbide performance in a range of workpiece materials. Machinists and tooling professionals working in aerospace, medical device, mold, and die applications will find this end mill suited for fine-detail work at small scales.

This end mill is intended for use in CNC machining centers and precision manual mills where micro-diameter tooling is required. The 0.125-inch shank diameter fits standard ER collets and toolholders commonly found in production and prototype shops. The 2.5-inch overall length combined with a 0.125-inch reach length and extended reach design allows access to features in confined areas without sacrificing rigidity. Single-end configuration means the tool is replaced rather than reindexed when worn.

Key Features

• 0.025-inch cutting diameter for micro-milling and fine-detail work
• 3-flute solid carbide construction for rigidity and wear resistance
• 42-degree variable helix reduces vibration and chatter during cut
• Centercutting design allows plunge entry into the workpiece
• Extended reach geometry provides access to recessed features
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-use micro end mill for CNC machining centers and precision mills accepting a 0.125-inch shank diameter via standard collet toolholders.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Seat the shank fully in the collet to the recommended minimum grip depth and torque the collet nut according to the toolholder manufacturer specifications. At this diameter, tool runout must be minimized at setup to prevent premature breakage.
