Accupro 12183609 Square End Mill 3/4 in 4 Flute Carbide

Product Description

The ACCUPRO 12183609 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin carbide, it provides the edge retention and rigidity needed for long-reach applications. The 4-flute spiral design with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.75 inches in diameter with a 2-inch length of cut and 6-inch overall length, this is a long-series end mill suited for deep-pocket and extended-reach milling where standard-length tools cannot reach. It is installed and run by machinists and CNC operators on vertical machining centers and manual mills.

This end mill is used in general-purpose milling applications requiring a long reach. The 3/4-inch shank diameter matches common ER collet and end mill holder sizes found in most machining setups. The centercutting geometry allows for direct plunge entry, eliminating the need for a pre-drilled start hole in many operations. It is well suited for slotting, profiling, and pocket milling in steel, aluminum, and similar workpiece materials in job shop and production environments.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 4-flute spiral design with 40-degree helix angle for smooth chip flow
• Centercutting geometry enables direct plunge milling
• Right-hand cut and right-hand flute configuration
• Long-series length with 2-inch length of cut for extended-reach applications
• Uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed as a direct-fit replacement for standard 3/4-inch shank square end mills in ER collet chucks, end mill holders, and Weldon-style holders with a 3/4-inch bore.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. The tool must be secured in a properly sized collet or end mill holder, torqued to the holder manufacturer's specification using the appropriate wrench. Ensure the machine spindle is fully stopped and the control is in E-stop or lock-out state before tooling changes. Verify runout with a dial indicator after installation to confirm proper seating before initiating a cut.
