Harvey Tool 894235-C3 Square End Mill 0.9mm 3 Flute Carbide

Product Description

The HARVEY TOOL 894235-C3 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. It features a 0.9 mm (0.0350 inch) cutting diameter, three flutes, and a 30-degree helix angle, making it well suited for finishing and light profiling in tight geometries. The AlTiN coating improves hardness and heat resistance at the cutting edge, extending tool life in ferrous and high-temperature alloy materials. With a 1/8 inch shank diameter and a 2.5 inch overall length, this end mill fits standard collet chucks on CNC machining centers and manual mills. Installation and operation require no special setup beyond standard collet selection for 1/8 inch tooling.

This end mill is intended for use in precision CNC milling, engraving, and micro-machining operations where small-diameter cutting tools are required. It is commonly used in mold and die work, aerospace component machining, and medical device manufacturing where tight tolerances and small feature sizes demand consistent tool geometry. The right-hand cutting and right-hand flute direction suit conventional CNC vertical and horizontal machining center configurations. This is a single-piece tool sold individually.

Key Features

• 0.9 mm (0.0350 inch) cutting diameter for small-feature and micro-milling work
• Three-flute geometry balances chip evacuation and surface finish
• 30-degree helix angle supports smooth cutting action in profiling operations
• AlTiN coating increases surface hardness and thermal resistance for longer tool life
• Solid carbide construction provides rigidity and wear resistance over high-speed steel alternatives
• Right-hand cut, right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8 inch collet chucks or compatible toolholders. This is a non-centercutting end mill; it is not intended for direct plunge cutting operations.

Installation Notes

Installation should be performed by a qualified machinist familiar with small-diameter carbide tooling. Power down and lock out the spindle before inserting or removing the tool from the collet. Secure the shank to the full recommended collet grip depth to minimize runout and prevent tool pullout during cutting. Carbide tooling is brittle — avoid dropping or contacting hard surfaces during handling.
