Accupro 12182438 Square End Mill 0.1969 in 4 Flute Carbide

Product Description

The ACCUPRO 12182438 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. This single-end, center-cutting tool features a 0.1969-inch (5.00 mm) mill diameter, a 0.6299-inch (16.00 mm) length of cut, and four spiral flutes with a 40-degree helix angle. The AlTiN (Aluminum Titanium Nitride) finish extends tool life in high-temperature cutting environments. Micrograin carbide substrate provides wear resistance and edge retention in demanding milling applications. Licensed machinists and CNC operators use this tool in vertical machining centers and manual mills for slotting, profiling, and plunge cuts.

This end mill is suited for regular-length milling tasks in job shops, production machining, and toolroom environments. The right-hand cut and right-hand flute configuration is the standard orientation for conventional CNC milling setups. The center-cutting design allows direct plunge entry without a pre-drilled pilot hole. The 6.00 mm (0.2362-inch) shank diameter fits standard collet chucks and end mill holders used across most 3-axis and 4-axis machining centers. Typical applications include finish profiling, pocket milling, and contour work in steel, stainless steel, cast iron, and hardened alloys where AlTiN coating provides thermal and abrasion resistance.

Key Features

• 0.1969-inch (5.00 mm) mill diameter with mill diameter tolerance of +0.000 / -0.002 inches
• 4-flute spiral design with 40-degree helix angle for efficient chip evacuation and smooth cutting action
• AlTiN finish for elevated heat resistance and extended tool life in hard and abrasive materials
• Center-cutting capability enables direct plunge entry without pre-drilling
• Micrograin solid carbide substrate delivers consistent edge geometry and wear resistance
• Right-hand cut and right-hand flute configuration matches standard CNC spindle rotation

Compatibility

Designed as an OEM-style replacement and standard-fitment solid carbide square end mill for use in collet chucks and end mill holders accepting a 6.00 mm shank diameter in vertical machining centers and CNC milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle drive before mounting or removing any cutting tool. Seat the shank fully into the collet or end mill holder and torque the retention mechanism to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut to confirm proper seating and avoid premature tool wear or workpiece damage.
