Accupro 12177208 Square End Mill 0.1969 in 4 Flute Carbide

Product Description

The ACCUPRO 12177208 is a solid carbide square end mill designed for precision milling operations in ferrous and hard materials. Built from micrograin carbide, it measures 0.1969 inches (5 mm) in cutting diameter with a 0.3937-inch (10 mm) length of cut and a 40-degree helix angle that promotes aggressive chip evacuation and reduced cutting forces. The AlTiN coating provides high heat resistance, making this end mill well-suited for dry machining and high-speed applications. At 0.1 pounds, it is a single-end, centercutting tool with a right-hand cut and right-hand spiral flute configuration. It is typically installed and operated by CNC machinists and tool-and-die professionals.

This end mill is built for extended-reach applications, with a 60 mm reach length and a 0.2362-inch (6 mm) shank diameter. It fits standard collet chucks and end mill holders used in vertical machining centers and CNC milling machines. Typical applications include slotting, profiling, and pocket milling in steel, stainless steel, cast iron, and similar materials where a small-diameter, high-performance tool is required. The centercutting geometry allows plunge entry into workpieces without a pre-drilled hole.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating supports dry and high-speed cutting with strong thermal resistance
• 40-degree helix angle promotes efficient chip flow and reduced heat buildup
• Extended reach design with 60 mm reach length for deep cavity and pocket work
• Centercutting geometry enables direct plunge milling without pilot drilling
• Right-hand cut and right-hand flute configuration for standard CNC spindle operation

Compatibility

Designed as an OEM-style replacement and standard fitment for CNC machining centers and manual mills accepting a 0.2362-inch (6 mm) shank diameter with standard collet or end mill holder tooling.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC toolholding systems. Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before changing tooling. Seat the shank fully into the collet or holder to the recommended gauge line and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.
