Harvey Tool 34625 Square End Mill 0.025 in 3 Flute Carbide

Product Description

The HARVEY TOOL 34625 is a solid carbide square end mill designed for 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 operations where accuracy and rigidity are critical. The three-flute geometry balances chip evacuation with cutting stability, making it well suited for ferrous and non-ferrous materials. A 30-degree helix angle promotes smooth cutting action and reduces deflection. The bright, uncoated finish leaves the carbide substrate exposed for applications where coating buildup or thermal sensitivity is a concern. Machinists and toolroom technicians working with CNC machining centers are the primary users of this end mill.

This end mill fits residential and commercial machine shop environments, as well as precision manufacturing and toolroom applications. It is a single-end, right-hand cut, right-hand flute tool with a 0.125 inch shank diameter and an overall length of 2.5 inches. The extended reach design, with a reach length of 0.203 inches, allows access to features that standard-reach end mills cannot reach. It is appropriate for slot milling, profiling, and finishing passes in small-scale or micro-machining setups on CNC milling equipment.

Key Features

• 0.025 inch cutting diameter for micro-milling and fine-detail work
• Three-flute design balances chip clearance and cutting rigidity
• 30-degree helix angle reduces cutting forces and deflection
• Extended reach with 0.203 inch reach length for deep or restricted-access features
• Centercutting geometry allows plunge entry into workpiece material
• Bright, uncoated solid carbide substrate suitable for a wide range of materials

Compatibility

Designed for use in CNC milling machines and machining centers that accept a 0.125 inch shank diameter. Suitable as a direct replacement or standard tooling selection for micro end mill applications requiring a 0.025 inch diameter, three-flute, square-profile tool.

Installation Notes

This end mill is installed by a machinist or toolroom technician into a compatible collet or end mill holder sized for a 0.125 inch shank. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the recommended insertion depth for the holder type in use and torque the collet nut per the holder manufacturer specification. At 0.025 inch diameter, this tool is highly susceptible to breakage from runout, misalignment, or excessive feed rates — verify holder runout before use.
