Accupro 12181600 Square End Mill 0.1575 in 2 Flute Carbide

Product Description

The ACCUPRO 12181600 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.1575-inch (4.00 mm) mill diameter and a 0.315-inch (8.00 mm) length of cut, this stub-length tool delivers rigidity in tight clearance setups. The 2-flute geometry and 40-degree helix angle promote efficient chip evacuation and smooth cutting action. A TiCN (Titanium Carbonitride) coating improves surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials. Machinist and CNC operators handling small-diameter work in production or job-shop environments will find this tool well-suited to their needs.

This end mill is suited for slot milling, peripheral milling, and light profiling operations in ferrous metals, stainless steel, aluminum, and similar materials. The stub-length configuration reduces deflection, making it appropriate for applications requiring dimensional accuracy. Centercutting capability allows plunge entry directly into the workpiece. Right-hand cut and right-hand flute orientation follow standard CNC and manual mill conventions. The 4.00 mm shank diameter matches the mill diameter for straightforward toolholder selection.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention in demanding cuts
• TiCN coating for increased surface hardness and extended tool life
• 40-degree helix angle supports efficient chip flow and reduced cutting forces
• Centercutting design allows direct plunge milling without a pre-drilled pilot hole
• Stub-length body minimizes deflection in close-tolerance operations
• Right-hand cut and right-hand flute orientation compatible with standard CNC setups

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 4.00 mm collet or end mill holders used in CNC machining centers and manual milling machines.

Installation Notes

This tool is installed and changed by qualified machinists or CNC setup personnel. Ensure the machine spindle is fully stopped and locked out before inserting or removing any end mill. Use a properly sized collet or end mill holder matching the 4.00 mm shank diameter and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges and coating for wear or chipping before each use and replace the tool if damage is observed.
