Accupro 12177202 Square End Mill 0.0787 in 4 Flute Carbide

Product Description

The ACCUPRO 12177202 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.0787 inch (2.00 mm) mill diameter and a 0.1969 inch (5.00 mm) length of cut, this end mill is built for tight-tolerance work in small-feature profiling and slotting. The 4-flute, spiral design with a 30-degree helix angle promotes efficient chip evacuation while maintaining a smooth surface finish. Coated in AlTiN for heat resistance and extended tool life, it is sized for use in CNC machining centers and manual mills where fine detail and dimensional accuracy are critical. A micrograin carbide substrate adds rigidity and wear resistance at small diameters.

This end mill is suited for small-feature milling in hardened steels, stainless steels, cast iron, and high-temperature alloys where AlTiN coating performance is most beneficial. The extended reach design, with a 20.00 mm reach length and a 6.00 mm shank diameter, allows access to deeper pockets and stepped features without excessive tool deflection. Centercutting capability allows both plunge and ramp entry cuts. Right-hand cut and right-hand flute orientation are standard for conventional CNC setups. This tool is appropriate for use by machinists, tool and die makers, and precision machine shops working with close-tolerance components.

Key Features

• 0.0787 inch (2.00 mm) mill diameter with mill diameter tolerance of +0.000 / -0.002 inches for close-tolerance applications
• AlTiN coating provides high heat resistance and extended tool life in ferrous and high-temperature alloy cutting
• 4-flute spiral design with 30-degree helix angle for efficient chip evacuation and improved surface finish
• Centercutting geometry enables plunge milling and ramp entry without a pre-drilled pilot hole
• Extended reach with 20.00 mm reach length and 6.00 mm shank for deep pocket and stepped-feature access
• Micrograin solid carbide substrate delivers rigidity and wear resistance at small diameters

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard CNC machining centers and manual milling machines accepting a 6.00 mm shank diameter collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the tool holder collet is clean and undamaged before seating the shank, and confirm runout with a dial indicator before engaging the workpiece. At this diameter, excessive side load or improper feed rates can cause tool breakage — follow the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type. Never exceed the rated depth of cut for the length-of-cut range of 0.100 to 0.200 inches.
