Accupro 12177401 Square End Mill 3/16 in 6 Flute Carbide

Product Description

The ACCUPRO 12177401 is a 6-flute solid carbide square end mill designed for precision milling operations in metal, composites, and engineering plastics. Built from micrograin carbide, this single-end tool runs a 45-degree helix angle with a spiral flute configuration, promoting efficient chip evacuation and smooth cutting action. At 0.1875 inches in diameter with a 0.5625-inch length of cut, it is sized for light, high-accuracy passes in tight geometries. The centercutting geometry allows plunge entry. Right-hand cut and right-hand flute orientation are standard. This tool is installed and operated by machinists and CNC programmers in job shop and production environments.

This end mill is suited for slot milling, profiling, and pocket milling in applications where a small-diameter, high-flute-count tool is required. The 6-flute design increases feed rates compared to 2- or 4-flute alternatives at equivalent chip loads, making it a practical choice for finishing passes and semi-finish operations in ferrous and non-ferrous materials. The 2-inch overall length keeps the tool compact and rigid, reducing deflection risk in close-tolerance work.

Key Features

• Micrograin solid carbide construction for hardness and wear resistance
• 6 flutes with 45-degree helix angle for improved surface finish and chip flow
• Centercutting geometry enables direct plunge entry
• Spiral flute design promotes efficient chip evacuation
• Right-hand cut and right-hand flute orientation
• No chipbreaker, no variable helix — consistent edge geometry throughout cut length

Compatibility

Designed as a standard shank end mill for use in CNC machining centers, manual mills, and collet-style toolholders accepting a 0.1875-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Secure the shank fully in a collet or end mill holder before operation, ensuring the holder is clean and free of chips that could affect runout. Confirm spindle speed and feed rate are appropriate for the workpiece material and cut depth before engaging the tool. Never exceed the rated length of cut when taking full-depth passes.
