Accupro 95168552 Square End Mill 3/16 in 5 Flute Carbide

Product Description

The ACCUPRO 95168552 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 3/16 inch cutting diameter with a 5/8 inch length of cut and five flutes for improved chip evacuation and surface finish. The variable helix geometry reduces harmonic vibration during cutting, which is critical when working with tighter tolerances or harder materials. An nACRo coating provides elevated heat resistance and wear protection, extending tool life in demanding applications. This end mill is single-end and center-cutting, making it suitable for plunge and slot milling. Machinists and tool-and-die professionals are the primary users.

This end mill is suited for use in CNC machining centers and manual mills where small-diameter, high-precision cuts are required. Its micrograin carbide construction and right-hand cutting and flute direction make it appropriate for ferrous and non-ferrous materials in both roughing and finishing passes. The 3/16 inch shank diameter matches the cutting diameter, allowing use in standard collets and end mill holders. The 2 inch overall length keeps the tool compact and rigid in confined setups.

Key Features

• 5-flute design improves material removal rate and surface finish compared to standard 4-flute tools
• Variable helix geometry reduces chatter and vibration during high-speed cutting
• nACRo coating provides enhanced hardness and thermal resistance for extended tool life
• Micrograin solid carbide construction for consistent edge integrity and dimensional stability
• Center-cutting capable for plunge entry without pre-drilled pilot holes
• Right-hand cutting and flute direction compatible with standard spindle rotation

Compatibility

Designed for use in standard 3/16 inch collets and end mill holders on CNC machining centers and manual milling machines requiring a single-end square profile tool.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling setup procedures. Ensure the machine spindle is fully stopped and locked before inserting or removing the end mill. Seat the shank fully within the collet or holder to the recommended grip length to prevent pullout during cutting. Follow machine manufacturer guidelines for runout inspection before initiating a cut.
