Accupro 12177075 Square End Mill 3/16 Inch 4 Flute Carbide

Product Description

The ACCUPRO 12177075 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 3/16 inch cutting diameter and a 40-degree helix angle, this tool delivers efficient chip evacuation and reduced cutting forces in a range of ferrous and non-ferrous materials. The AlTiN coating provides elevated heat and wear resistance, extending tool life in high-speed and dry-cutting applications. The micrograin carbide substrate supports sharp, consistent cutting edges. This end mill is installed and operated by machinists and CNC programmers working in job shops, production machining, and tool-and-die environments.

This end mill is suited for slotting, profiling, and peripheral milling in both manual and CNC machining centers. The centercutting design allows plunge entry into workpieces without a pre-drilled pilot hole. Right-hand cut and right-hand flute configuration follows standard spindle rotation. The 5/8 inch length of cut and 2 inch overall length make this tool appropriate for shallow-to-moderate depth passes in tight-tolerance work on steel, stainless steel, cast iron, and similar materials.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN finish for heat resistance and extended tool life in ferrous materials
• 40-degree spiral helix angle promotes efficient chip evacuation
• Centercutting capable - supports direct plunge entry
• Right-hand cut, right-hand flute for standard CNC spindle compatibility
• 4-flute design balances material removal rate with surface finish quality

Compatibility

Designed as a standard single-end square end mill for use in CNC machining centers and manual mills with a 3/16 inch collet or end mill holder.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Secure the shank in a properly sized collet or end mill holder and verify runout before operation. Ensure the machine spindle is fully stopped before changing tooling. Adhere to the machine manufacturer's recommended speeds and feeds for the workpiece material and tool diameter.
