Accupro 12181433 Square End Mill 0.3937 in 2 Flute Carbide

Product Description

The ACCUPRO 12181433 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 0.3937 inch (10 mm) mill diameter and a 40-degree helix angle, this tool delivers aggressive chip evacuation and a clean finish in a wide range of machining applications. The 2-flute, spiral flute geometry with right-hand cut and right-hand flute direction makes it well suited for slotting, profiling, and peripheral milling. Micrograin carbide construction provides hardness and wear resistance in demanding cutting environments. The uncoated finish is appropriate for applications where coating compatibility or regrinding flexibility is a priority.

This end mill fits standard CNC machining centers, vertical mills, and manual knee mills used in job shop, production, and maintenance machining environments. With a 0.9843 inch (25 mm) length of cut and a 2-3/4 inch overall length, it handles regular-length milling passes without excessive overhang. The centercutting design allows plunge entry, making it versatile for pocketing operations. It is installed and used by machinists, tool-and-die makers, and CNC operators working with aluminum, steel, cast iron, and similar workpiece materials.

Key Features

• 0.3937 inch (10 mm) diameter with mill diameter tolerance of +0.000 / -0.002 inches for consistent fitment
• Solid micrograin carbide construction for hardness and wear resistance
• 40-degree helix angle spiral flute for efficient chip evacuation
• Centercutting capability allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute direction - standard orientation for conventional CNC setups
• Uncoated finish suitable for regrinding and use in applications where coatings are not required

Compatibility

Designed as an OEM-style replacement and standard-fitment solid carbide square end mill for use in CNC machining centers, vertical mills, and similar equipment accepting a 10 mm (0.3937 inch) shank diameter toolholder.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or drawbar is de-energized before inserting or removing the end mill. Seat the shank fully in a collet or end mill holder and torque the retention hardware to the toolholder specification. Verify runout with a dial indicator before beginning a production cut.
