Accupro 12177206 Square End Mill 0.1575 in 4 Flute Carbide

Product Description

The ACCUPRO 12177206 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.1575-inch mill diameter and a 0.315-inch length of cut, this tool handles slotting, profiling, and peripheral milling in tight-tolerance work. The four-flute, spiral design features a 40-degree helix angle and an AlTiN coating, which increases heat resistance and tool life when cutting ferrous and hardened materials. The micrograin carbide substrate provides edge retention under high cutting loads. It is centercutting, allowing plunge entry, and features an extended reach configuration with a reach length of 1.496 inches.

This end mill is suited for CNC machining centers and manual mills used in tool-and-die, mold making, aerospace component, and precision parts manufacturing. Its 0.2362-inch shank diameter fits standard collets and tool holders common in production and job-shop environments. The right-hand cut and right-hand flute configuration is the standard orientation for conventional and climb milling operations. It is appropriate for use in dry, mist, or through-spindle coolant setups depending on machine capability and material being cut.

Key Features

• AlTiN coating for elevated heat resistance and extended tool life in ferrous materials
• 40-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting geometry enables direct plunge entry without pre-drilling
• Micrograin solid carbide substrate for superior hardness and edge retention
• Extended reach design with 1.496-inch reach length for deeper cavity access
• Four flutes with spiral configuration for efficient material removal and surface finish

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for CNC machining centers and manual mills accepting a 0.2362-inch shank diameter. Suitable for length-of-cut requirements in the 0.300 to 0.500-inch range per manufacturer specification.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify collet or end mill holder bore matches the 0.2362-inch shank diameter within specified tolerance before tightening. Confirm runout after installation and refer to the machine tool manufacturer guidelines for appropriate cutting parameters.
