Accupro 12183150 Square End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12183150 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous metals. Built from micrograin carbide stock, it delivers the hardness and edge retention required for demanding cutting applications. The 4-flute, spiral-flute geometry paired with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN coating adds heat and oxidation resistance, extending tool life in high-speed and dry-cutting environments. This end mill is centercutting, allowing it to plunge directly into material when needed. It is installed and operated by machinists in job shop, production, and maintenance machining environments.

This end mill suits long-reach applications where a standard-length tool would not clear the workpiece or fixture. The 2.25-inch length of cut and 5.0-inch overall length place it in the long-length category, making it appropriate for deep-pocket milling, slotting, and profiling operations on mills and machining centers. Right-hand cut and right-hand flute orientation are standard for conventional spindle operation. The 0.75-inch shank diameter fits standard ER, hydraulic, shrink-fit, and Weldon-style toolholders sized for 3/4-inch shanks.

Key Features

• Solid micrograin carbide construction for high hardness and edge retention
• AlTiN coating for heat resistance and extended tool life in high-speed or dry cutting
• 40-degree helix angle with spiral flutes for efficient chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge entry into material
• Long-length configuration with 2.25-inch length of cut for deep-pocket and hard-to-reach applications
• Right-hand cut and right-hand flute for standard CNC and manual mill spindle operation

Compatibility

Designed for use in standard 3/4-inch toolholders including ER collet chucks, hydraulic chucks, shrink-fit holders, and Weldon-style holders on CNC machining centers and manual vertical mills.

Installation Notes

Installation is performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Confirm toolholder bore and collet size match the 0.75-inch shank diameter before seating the tool. Verify runout after installation and before cutting, as excessive runout accelerates edge wear on carbide tooling.
