Accupro 95168474 Square End Mill 3/8 in 5 Flute Carbide

Product Description

The ACCUPRO 95168474 is a solid carbide square end mill designed for precision metal removal in milling applications. It features a 3/8 inch diameter cutting head with five flutes and a variable helix geometry that reduces chatter and harmonics during cut, improving surface finish and tool life. The cutting edge is nACRo coated, a nanocomposite coating that resists heat and wear at elevated cutting speeds. With a 1/2 inch length of cut and 2 inch overall length, this tool is suited for finishing and semi-finishing passes in tight-tolerance work. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills.

This end mill is intended for use in ferrous and non-ferrous machining environments where high-performance tooling is required. The variable helix flute design makes it well suited for hardened steels, stainless, and difficult-to-machine alloys where standard end mills exhibit vibration. The single-end configuration and right-hand cutting and flute direction are standard for most vertical machining center spindles. It is appropriate for both production shops and maintenance machining operations requiring repeatable precision cuts.

Key Features

• 3/8 inch mill diameter with micrograin solid carbide construction for rigidity and wear resistance
• 5-flute variable helix geometry reduces chatter and improves finish quality
• nACRo nanocomposite coating extends tool life in high-heat cutting conditions
• Right-hand cut and right-hand spiral flute direction compatible with standard CNC spindle rotation
• Centercutting design allows plunge entry without a pre-drilled hole
• Mill diameter tolerance of +0.000 / -0.002 inches for close-tolerance fitment

Compatibility

Designed as a direct-fit tooling option for standard 3/8 inch collets and tool holders used in CNC vertical machining centers and manual knee mills with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Power down and lock out the spindle before inserting or removing the end mill from the tool holder. Ensure the collet or end mill holder is clean and free of chips before seating the shank. Verify runout with a dial indicator after installation to confirm proper seating before beginning a cut.
