Accupro 12181522 Square End Mill 16mm 2 Flute Carbide Ticn

Product Description

The ACCUPRO 12181522 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 16 mm (0.6299 inch) cutting diameter and a 32 mm length of cut, it handles slotting, profiling, and peripheral milling in a single-end configuration. The 40-degree helix angle promotes efficient chip evacuation, and the TiCN (titanium carbonitride) coating increases surface hardness and wear resistance. Micrograin carbide construction provides rigidity and edge retention across ferrous and non-ferrous workpiece materials. This tool is installed by machinists and CNC operators working in job shop, production, and tool room applications.

This end mill is suited for milling operations on steel, stainless steel, cast iron, and non-ferrous alloys in both manual and CNC milling machines. The 16 mm shank diameter matches the cutting diameter, allowing direct chuck or collet mounting without a reduction sleeve. The regular length designation makes it appropriate for standard-depth milling where extended reach is not required. Right-hand cut and right-hand flute geometry follow conventional milling orientation. Its centercutting capability allows plunge entry as well as lateral cutting passes, making it versatile for pocketing and contouring operations.

Key Features

• 16 mm cutting diameter with plus 0.000 / minus 0.002 inch diameter tolerance for consistent fit and finish
• TiCN coating for improved hardness, lubricity, and tool life in ferrous materials
• 40-degree helix angle promotes aggressive chip evacuation and reduces cutting forces
• Micrograin solid carbide substrate provides superior edge retention versus HSS or cobalt alternatives
• Centercutting design supports plunge milling and full-slot entry
• 2-flute geometry balances chip clearance with cutting engagement in moderate-to-deep cuts

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC machining centers and manual knee mills accepting a 16 mm straight shank via ER collet, end mill holder, or equivalent toolholding system.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before inserting or removing the tool from any toolholder. Ensure the shank is clean and free of chips before seating in the collet or holder; shank diameter tolerance is minus 0.0001 to minus 0.0004 inch and requires a matching collet size. Confirm correct spindle direction (right-hand) and appropriate feed and speed parameters for the workpiece material before initiating a cut.
