Accupro 14981774 Square End Mill 1/16 in 3 Flute Carbide

Product Description

The ACCUPRO 14981774 is a single-end, solid carbide square end mill designed for precision milling in ferrous and steel workpiece applications. With a 1/16 inch (0.0625 inch) mill diameter and three right-hand spiral flutes at a 30-degree helix angle, this tool delivers clean, efficient chip evacuation in tight-geometry cuts. The AlTiN coating provides high heat resistance and extended tool life under demanding cutting conditions. At 2.5 inches overall length with a 3/8 inch length of cut, this extra-long configuration reaches into deeper pockets and slots that standard-length end mills cannot access.

This end mill is suited for precision machining operations in job shops, tool rooms, and production environments where small-diameter, long-reach milling is required. The 1/8 inch straight shank fits standard collets and tool holders common in CNC machining centers and manual mills. The center-cutting geometry allows direct plunge entry without a pre-drilled hole. Primary workpiece material designation is Steel (ISO material code P), making it appropriate for mild steels, alloy steels, and similar ferrous materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in steel cutting
• AlTiN coating for high-temperature oxidation resistance and extended tool life
• Three right-hand spiral flutes with 30-degree helix angle for efficient chip removal
• Center-cutting capable — supports direct plunge and ramping operations
• Extra-long series 524 design with 2.5 inch overall length for deep-reach applications
• 1/8 inch straight shank for compatibility with standard collet systems

Compatibility

Designed as an OEM-style replacement and standard fitment for CNC machining centers and manual milling machines equipped with 1/8 inch collets or tool holders accepting a straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and de-energize the machine spindle before inserting or removing the end mill from the collet. Ensure the collet and tool holder are clean and free of debris before seating the shank to the recommended engagement depth. Small-diameter carbide end mills are brittle and should not be used for interrupted cuts or heavy side loads beyond the rated geometry.
