Accupro 12177209 Square End Mill 0.2362 in 4 Flute Carbide

Product Description

The ACCUPRO 12177209 is a solid carbide square end mill designed for precision milling in metal, composite, and hard-material applications. This single-end tool features a 0.2362-inch (6.00 mm) mill diameter, four spiral flutes with a 40-degree helix angle, and a long-reach configuration with an extended reach length of approximately 2.441 inches (62.00 mm). The micrograin carbide construction delivers edge retention and rigidity at elevated cutting speeds. Right-hand cut and right-hand flute geometry make it compatible with standard CNC machining center setups. Centercutting capability allows plunge entry directly into the workpiece. Installed by machinists and tool-and-die professionals in production and job-shop environments.

This end mill is suited for slots, pockets, profiling, and contour milling operations where a longer reach is required to access deep features or tall workpiece geometries. The 0.4724-inch (12.00 mm) length of cut falls within the 0.300- to 0.500-inch range typical for this diameter class. The uncoated micrograin carbide substrate performs well in aluminum, brass, and softer ferrous materials, and pairs with coatings or cutting fluids when required by the application. It is a long-length variant, making it appropriate where standard-length tools cannot reach the cut zone.

Key Features

• 0.2362-inch (6.00 mm) mill diameter with a tolerance of +0.000 / -0.002 inches
• 4-flute spiral geometry with 40-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Extended reach length of approximately 2.441 inches (62.00 mm) for deep-feature access
• Micrograin solid carbide construction for rigidity and edge retention
• Right-hand cut, right-hand flute — compatible with standard CNC spindle rotation
• Uncoated finish; compatible with cutting fluid or coolant application

Compatibility

Designed as an OEM-style replacement or direct-procurement solid carbide square end mill for CNC machining centers and manual mills accepting a 6.00 mm (0.2362-inch) shank diameter with a shank tolerance of -0.0001 / -0.0004 inches.

Installation Notes

Installation is performed by qualified machinists using an appropriate collet or end mill holder sized for the 6.00 mm shank diameter. Confirm runout and tool projection before initiating a cut, particularly given the extended reach length. Power down and lock out the spindle before changing or seating tooling. Follow shop SOP and machine manufacturer guidelines for speed, feed, and depth-of-cut parameters appropriate to the workpiece material.
