Osg 3181841 Square End Mill 0.1614 in 2 Flute Carbide

Product Description

The OSG 3181841 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a mill diameter of 0.1614 inches (4.10 mm) and a length of cut of 0.2441 inches (6.20 mm), this stub-length tool is built for tight-tolerance work in confined areas. The WXL finish reduces friction and extends tool life in demanding materials. This is a centercutting, right-hand cut, right-hand flute tool with a 30-degree spiral helix. It is sold individually and installed by machinists and CNC operators working in job shop, production, or toolroom settings.

This end mill is suited for slotting, profiling, and plunge cutting in ferrous and non-ferrous materials where a small-diameter, high-rigidity tool is required. The extra fine carbide grade provides edge integrity at elevated surface speeds. The stub length reduces deflection in shallow-depth applications, making it a practical choice for precision contouring and fine detail work on CNC machining centers and manual mills.

Key Features

• 0.1614 inch (4.10 mm) mill diameter with a mill diameter tolerance of +0.00 / -0.02 mm
• 0.2441 inch (6.20 mm) length of cut — stub length for reduced deflection
• 2-flute design supports both slotting and plunge cutting
• 30-degree spiral helix promotes efficient chip evacuation
• WXL coating finish extends tool life and reduces built-up edge
• Solid carbide construction with extra fine material grade for edge retention

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual milling machines accepting a 6.00 mm shank diameter, within the OSG Series 3720 product line.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Secure the shank fully in a collet or end mill holder rated for the 6.00 mm shank diameter before operation. Verify spindle direction matches the right-hand cut specification before engaging the workpiece. Inspect the cutting edges and coating prior to each use — do not run a chipped or worn tool.
