Accupro 95168350 Square End Mill 1/4 in 4 Flute Carbide

Product Description

The ACCUPRO 95168350 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining applications. With a 0.250-inch mill diameter, a 3/8-inch (0.375-inch) length of cut, and a 2-inch overall length, this single-end tool is built for tight tolerances and consistent performance. The four-flute, right-hand spiral design paired with a variable helix geometry helps reduce harmonic chatter and improve surface finish. The nACRo coating provides enhanced hardness and thermal resistance, making this end mill suitable for demanding cutting conditions in ferrous and hard materials. It is installed and used by machinists and CNC operators in production and job-shop environments.

This end mill is suited for milling slots, pockets, profiles, and contours in a range of metalworking applications. The micrograin carbide substrate provides edge strength and wear resistance for extended tool life. The center-cutting capability allows for direct plunge entry without a pre-drilled hole. With a 1/4-inch shank diameter matching the mill diameter, it fits standard 1/4-inch collets and tool holders used in vertical machining centers, CNC mills, and manual knee mills. The variable helix design makes it particularly effective in applications where chatter suppression is critical.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• nACRo coating for high hardness and thermal resistance in demanding cuts
• Variable helix flute geometry reduces chatter and improves surface finish
• Center-cutting design allows direct plunge milling
• Right-hand cut and right-hand flute direction for standard spindle use
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit

Compatibility

Designed for use in standard 1/4-inch collets and end mill holders on CNC machining centers, vertical mills, and similar equipment. Confirm holder and collet clearance before use.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Power down and lock out the spindle before loading or unloading the tool. Ensure the shank is fully seated in the collet or tool holder and that the holder is torqued to the machine manufacturer's specification. Inspect the cutting edges for chips or wear before each use and replace the tool if edge condition is compromised.
