Accupro 12178611 Square End Mill 5/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12178611 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It carries a 5/8 inch cutting diameter with a 7/8 inch length of cut and a 3 inch overall length. The three-flute geometry paired with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Machined from micrograin carbide stock, this tool delivers the rigidity and edge retention required for demanding production environments. It is a stub-length configuration, making it well suited for applications where rigidity is prioritized over reach.

This end mill fits standard machining center and manual milling applications where a 5/8 inch shank is required. The centercutting design allows plunge entry, expanding its utility across slotting, profiling, and pocketing operations. Right-hand cut with right-hand spiral flutes is the standard orientation used in the majority of CNC and manual mill setups. The uncoated finish makes this tool a straightforward choice for general-purpose work or for shops that apply their own coatings to custom specifications.

Key Features

• Solid micrograin carbide construction for high edge retention and wear resistance
• 3-flute spiral design with 40-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge milling without a pilot hole
• Stub-length configuration maximizes rigidity and minimizes deflection
• Right-hand cut and right-hand flute orientation for standard spindle compatibility
• Mill diameter tolerance of +0.000 / -0.002 inches ensures consistent fit and finish

Compatibility

Designed as a standard 5/8 inch shank square end mill for use in CNC machining centers, knee mills, and manual milling machines that accept 5/8 inch tool holders or collets.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before inserting or removing the tool. Seat the shank fully into the collet or tool holder to the recommended engagement depth before torquing the retention hardware. Inspect the cutting edges for chips or damage before each use and discard the tool if edge integrity is compromised.
