Harvey Tool 34608 Square End Mill 0.2 Mm 3 Flute Carbide

Product Description

The HARVEY TOOL 34608 is a solid carbide square end mill designed for high-precision micro-machining applications. With a 0.2 mm (0.0080 inch) cutting diameter and a 0.3 mm (0.012 inch) length of cut, this tool is built for fine detail work where dimensional accuracy is critical. The three-flute geometry and 30-degree right-hand helix promote chip evacuation and surface finish quality in demanding materials. Extended reach design provides access to deep or confined features. This end mill is single-end and ships bright/uncoated, making it suitable for non-ferrous metals, plastics, and similar materials where coating is not required. Machinists and tool-and-die professionals specify this type of tooling for prototype work, mold details, and precision component manufacturing.

This end mill is suited for CNC milling centers performing micro-scale operations in industries such as medical device manufacturing, electronics, aerospace component work, and precision mold making. The 0.125 inch (1/8 inch) shank diameter is compatible with standard collet systems commonly found on high-speed machining centers and micro-milling platforms. The 2.5 inch overall length and extended reach configuration allow access to features that standard-reach tooling cannot reach. The non-centercutting design means this tool is intended for peripheral and side milling rather than plunge cutting.

Key Features

• 0.2 mm (0.0080 inch) cutting diameter for micro-precision milling
• 3-flute right-hand geometry with 30-degree helix for improved chip flow
• Solid carbide construction for rigidity and wear resistance at small diameters
• Extended reach design with 0.065 inch reach length for deep-feature access
• Bright/uncoated finish suitable for non-ferrous and non-abrasive materials
• Single-end, non-centercutting — intended for peripheral and slot milling

Compatibility

Designed for use in CNC milling machines equipped with standard 1/8 inch collet or toolholder systems. Compatible with high-speed spindles used in micro-machining applications. No specific model compatibility data was provided by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before inserting or removing the end mill. Use a properly sized collet rated for 0.125 inch shank tooling and torque the collet nut to the machine manufacturer's specification. At this diameter, tool runout must be minimized — verify runout with a test indicator before cutting. This tool is not designed for plunge entry; use helical or ramping entry strategies when required.
