Accupro 12182254 Square End Mill 1/2 in 3 Flute Carbide Ticn

Product Description

The ACCUPRO 12182254 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 1/2-inch cutting diameter, a 3-inch length of cut (LOC), and a 6-inch overall length, this is an extra-long configuration suited for deep-cavity and extended-reach applications. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN (Titanium Carbonitride) coating adds surface hardness and wear resistance, extending tool life in abrasive materials. This tool is installed and operated by machinists and CNC operators working with milling machines and machining centers.

This end mill is appropriate for general-purpose and high-performance milling of ferrous and non-ferrous metals, alloys, and similar materials where an extra-long reach is required. The 3-flute geometry balances chip clearance with rigidity, making it effective for slotting, side milling, and profiling in tight pockets or deep features. The right-hand cutting and right-hand flute direction suit standard CNC and manual mill spindle configurations. Micrograin carbide construction supports use in demanding cutting conditions where tool deflection and wear must be minimized.

Key Features

• 1/2-inch mill diameter with a matching 1/2-inch shank diameter for secure toolholder engagement
• 3-inch length of cut supports deep-cavity and extended-reach milling applications
• 6-inch overall length classified as extra long for reach into deep workpiece features
• 40-degree helix angle for efficient chip flow and reduced cutting forces
• TiCN coating provides elevated surface hardness and abrasion resistance
• Micrograin solid carbide substrate for rigidity and edge retention
• Center-cutting capable, allowing plunge entry into workpieces

Compatibility

Designed as an OEM-style replacement or standard tooling selection for 1/2-inch collet or end mill holders used in CNC machining centers and manual milling machines with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the milling machine spindle is fully stopped and locked out before inserting or removing tooling. Seat the shank fully into a clean, properly sized collet or end mill holder and torque the retention mechanism to the toolholder manufacturer's specification. Inspect the cutting edges for chips or damage before each use, and verify runout with a dial indicator after installation.
