Harvey Tool 33260-C3 Square End Mill 0.06in 3 Flute Altin

Product Description

The HARVEY TOOL 33260-C3 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.06 inch cutting diameter and a 3/32 inch length of cut, this tool is built for tight-tolerance finishing and profiling in confined areas. The three-flute geometry paired with a 30-degree helix angle improves chip evacuation and surface finish quality. An AlTiN coating adds heat and wear resistance, making this end mill effective in hard and abrasive materials. The extended reach design and 5/16 inch reach length provide access to deep pockets and stepped features that shorter tools cannot reach.

This end mill is suited for CNC machining centers and manual mills in job shop, production, and toolroom environments. It is a single-end, right-hand cutting and right-hand flute tool with centercutting capability, allowing plunge entry into workpieces. The 1/8 inch shank diameter fits standard collets and end mill holders common on benchtop and full-size vertical machining centers. Typical materials include hardened steels, stainless steel, titanium, and other difficult-to-machine alloys where AlTiN coating performance is most effective.

Key Features

• 0.06 inch cutting diameter for fine detail and small-feature milling
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for improved performance in hard and high-temperature materials
• 30-degree helix angle promotes smooth cutting action and chip flow
• Extended reach with 5/16 inch reach length for deep pocket access
• Centercutting design allows direct plunge entry

Compatibility

Designed for use in standard 1/8 inch collets and end mill holders on CNC machining centers and manual vertical mills. Compatible with applications requiring a length of cut up to 0.10 inch.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the collet and holder are clean and free of debris before seating the shank. Micro-diameter end mills require careful runout verification after installation to avoid breakage during initial cuts. Follow the machine tool manufacturer guidelines for speed, feed, and depth of cut when working with small-diameter carbide tools.
