Accupro 12185420 Solid Carbide Square End Mill 3/16 Inch

Product Description

The ACCUPRO 12185420 is a solid carbide square end mill designed for both roughing and finishing operations in a single tool. The 4-flute, right-hand cutting configuration with a 40-degree helix angle delivers aggressive material removal while maintaining surface quality on the finish pass. A chipbreaker geometry reduces cutting forces and helps evacuate chips in deep-slot or extended-reach applications. At 3/16 inch in diameter with a 1-1/8 inch length of cut and 3 inch overall length, this tool is suited for close-tolerance work in ferrous and non-ferrous materials. It ships uncoated and is intended for use by machinists and tool-and-die professionals.

This end mill is used in CNC machining centers and manual mills for slotting, profiling, and pocketing operations where a single tool must handle both stock removal and finish work. The extra long length relative to diameter makes it appropriate for deep cavity work or applications requiring extended reach. The single-end design and right-hand flute direction are standard for conventional and climb milling setups on vertical machining centers. It is commonly used in job shops, toolrooms, and production environments working with steel, aluminum, and similar materials.

Key Features

• 4-flute right-hand configuration supports both roughing and finishing in one tool
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Chipbreaker geometry reduces cutting forces in deep slots and long-reach setups
• Solid carbide construction provides rigidity and wear resistance
• Uncoated finish suitable for use with cutting fluids across a range of work materials
• Extra long length of cut relative to diameter allows deep cavity and extended-reach milling

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 3/16 inch collet or end mill holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerance. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly sized collet or end mill holder rated for the 3/16 inch shank diameter to prevent tool pullout. Verify tool projection and length of cut engagement before initiating a cutting cycle.
