Accupro 12181806 Square End Mill 3/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12181806 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. It features a 3/16 inch cutting diameter, a 1 inch length of cut, and a 4 inch overall length, making it well-suited for extended-reach applications where a standard-length tool falls short. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Micrograin carbide construction provides the edge retention and rigidity needed for demanding cuts. This is a single-end, centercutting tool, meaning it can plunge directly into a workpiece as well as cut laterally.

This end mill is used in CNC machining centers, manual knee mills, and similar setups for slotting, profiling, and plunge-milling operations. The long-length configuration suits applications where reach into a deep pocket or a tall workpiece is required. It is a standard choice for machinists, tool-and-die shops, and maintenance shops working with ferrous and non-ferrous stock. The uncoated finish makes it suitable for aluminum and other non-ferrous applications where coatings can cause material adhesion.

Key Features

• Micrograin solid carbide construction for superior edge retention and rigidity
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting geometry allows direct plunge entry into workpiece
• Right-hand cut with right-hand spiral flute for standard CNC and manual mill spindles
• Long-length designation with 4 inch OAL for extended-reach applications
• Uncoated finish suited for aluminum and non-ferrous materials

Compatibility

Designed as a standard 3/16 inch shank square end mill compatible with collet systems and tool holders accepting a 3/16 inch round shank, including ER collets and standard end mill holders on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the shank to the full engagement depth recommended by the tool holder manufacturer to prevent pullout during cutting. Inspect the cutting edges for chips or wear before each use, as carbide tools can fracture under interrupted cuts if edge integrity is compromised.
