Accupro 12178795 Square End Mill 3/8 in 2 Flute Carbide

Product Description

The ACCUPRO 12178795 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin carbide stock, it measures 3/8 inches in diameter with a 5/8-inch length of cut and a 2-inch overall length. The nACRo PVD coating provides enhanced wear resistance and lubricity, extending tool life in ferrous and non-ferrous materials. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This is a stub-length, single-end tool suited for high-accuracy profiling, slotting, and peripheral milling in CNC machining centers and manual mills.

This end mill is configured for right-hand cut with right-hand flute spiral geometry and a centercutting design, allowing plunge entry into workpieces. Stub-length geometry increases rigidity and reduces deflection, making it well suited for shallow-pocket work and applications where tool reach is not the primary requirement. The 3/8-inch shank diameter matches standard collet toolholders commonly found in CNC mills and machining centers used in job shops, tool-and-die, and production machining environments.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• nACRo coating for extended tool life in demanding cut conditions
• 40-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Stub-length body increases rigidity and reduces deflection
• Right-hand cut, right-hand flute spiral configuration

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for 3/8-inch collet toolholders on CNC machining centers and manual milling machines accepting standard straight-shank end mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning the cut, particularly in tight-tolerance applications.
