Accupro 12182790 Square End Mill 0.2362 in 4 Flute Carbide

Product Description

The ACCUPRO 12182790 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide, this tool delivers the rigidity and edge retention needed for demanding cuts in ferrous and non-ferrous materials. It features a 0.2362 inch diameter, a 0.4724 inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The stub length configuration provides added stiffness, reducing deflection in tight-tolerance operations. This end mill is centercutting, allowing plunge entry as well as conventional peripheral milling. It is sold as a single unit and is intended for use in CNC machining centers and manual mills operated by qualified machinists.

This tool is suited for slot milling, profiling, and plunge operations in production and job-shop environments. The right-hand cut and right-hand spiral flute geometry follows standard convention for the majority of CNC spindle setups. The uncoated micrograin carbide construction makes it a practical choice for aluminum, brass, and other non-ferrous materials, as well as light steel cuts where a coating is not required. Its 6 mm shank diameter is compatible with standard ER collets and end mill holders used across a wide range of machining centers.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• 4-flute spiral design with 40-degree helix angle for efficient chip flow
• Centercutting geometry allows direct plunge entry into workpiece
• Stub length body reduces deflection and increases rigidity in close-tolerance cuts
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Uncoated finish suitable for non-ferrous metals and general-purpose milling

Compatibility

Designed for use with standard 6 mm ER collets and end mill holders on CNC machining centers and manual milling machines requiring a 0.2362 inch square end mill.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully within the collet or tool holder to the manufacturer-recommended engagement depth before tightening. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify runout with a dial indicator after installation to confirm proper seating and avoid premature tool wear.
