Accupro 12183285 Square End Mill 3/8 in 4 Flute Carbide Ticn

Product Description

The ACCUPRO 12183285 is a solid carbide square end mill designed for precision milling operations across a wide range of ferrous and non-ferrous materials. It features a 3/8 inch cutting diameter, a 1-3/4 inch length of cut, and a 4 inch overall length, placing it in the extra long category for improved reach in deep-pocket and stepped-surface applications. The four-flute spiral design runs a 40-degree helix angle with a TiCN coating, which increases surface hardness and reduces built-up edge. The micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades. Installed by machinists and tool-and-die professionals, this end mill suits both manual and CNC milling machines.

This end mill is suited for slot milling, profiling, and contouring on vertical and horizontal milling centers. The centercutting geometry allows plunge entry, making it practical for applications where a pilot hole is not pre-drilled. The extra long OAL is particularly useful when clearing tall workpiece features or milling at extended reach without a long-reach adapter. Right-hand cut and right-hand flute orientation are standard for conventional CNC spindle configurations.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance at elevated cutting speeds
• TiCN coating reduces friction and extends tool life in steel and cast iron applications
• 40-degree spiral helix promotes efficient chip evacuation and smooth surface finish
• Centercutting design enables direct plunge milling without pre-drilling
• Extra long 4 inch OAL provides extended reach for deep features and stepped setups
• Right-hand cut, right-hand flute — compatible with standard CNC and manual mill spindle rotation

Compatibility

Designed as a standard shank square end mill for use in 3/8 inch collets, end mill holders, shrink-fit holders, or hydraulic tool holders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully within the tool holder to the minimum insertion depth recommended for the holder type, and torque retention screws or collet nuts per the holder manufacturer specification. Inspect the tool for chips or cracks before mounting. Verify spindle rotation direction matches the right-hand cut orientation before engaging the workpiece.
