Accupro 95168330 Square End Mill 3/8 in 5 Flute Carbide

Product Description

The ACCUPRO 95168330 is a solid carbide square end mill designed for precision milling operations in demanding metalworking and machining environments. With a 3/8-inch mill diameter, 1-1/2-inch length of cut, and 5 flutes, this tool delivers efficient chip evacuation and a fine surface finish on ferrous and non-ferrous materials. The 45-degree helix angle promotes smooth cutting action and reduces chatter. An AlTiN coating provides thermal resistance and extended tool life at elevated cutting speeds. This is a right-hand cut, right-hand flute, single-end configuration, and is centercutting-capable for plunge operations.

This end mill is suited for milling slots, pockets, profiles, and contours in hardened steels, stainless steels, cast iron, and similar materials. The long-length designation and 4-inch overall length make it appropriate for jobs requiring extended reach into deep pockets or stepped features. It is commonly used in CNC machining centers and manual mills in production shops, tool-and-die operations, and precision fabrication environments. Micrograin carbide construction supports consistent performance at high spindle speeds.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for high-temperature performance and extended tool life
• 5-flute design improves feed rates and surface finish compared to standard 4-flute geometry
• 45-degree helix angle reduces cutting forces and minimizes chatter
• Centercutting capable — supports plunge and ramp entry cuts
• Right-hand cut and right-hand spiral flute for standard CNC and manual mill compatibility
• Long-length configuration at 4 inches OAL for extended-reach applications

Compatibility

Designed for use in standard 3/8-inch collet chucks, end mill holders, and shrink-fit toolholders on CNC machining centers and manual milling machines. Verify toolholder runout and clamping specifications before use.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Insert the shank fully into the toolholder to the recommended engagement depth and torque the set screw or collet nut per the toolholder manufacturer specifications. Inspect the cutting edges for chips or coating damage before each use.
