Osg 3181832 Square End Mill 0.126 in 2 Flute Solid Carbide

Product Description

The OSG 3181832 is a solid carbide square end mill designed for precision milling in metalworking and machining operations. It features a 0.1260-inch mill diameter, a 0.189-inch length of cut, and a 0.2362-inch shank diameter, making it a compact stub-length tool suited for controlled, rigid setups. The two-flute geometry with a 30-degree helix angle and right-hand spiral flute promotes efficient chip evacuation in tight spaces. The WXL coating extends tool life in abrasive materials. Machined from micrograin solid carbide, this end mill delivers consistent dimensional accuracy and is centercutting capable, allowing direct plunge entry.

This end mill is intended for use in CNC machining centers and manual mills where small-diameter, high-precision cutting is required. The stub length design minimizes deflection, making it well suited for shallow-cavity milling, slotting, and profiling in ferrous and non-ferrous materials. It belongs to OSG Series 3720 and is appropriate for job shops, tool rooms, and production environments where tight tolerances are critical.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• WXL coating for extended tool life in abrasive and harder materials
• 30-degree helix angle with right-hand spiral flute for efficient chip flow
• Centercutting design allows plunge milling entry
• Stub length reduces overhang and minimizes deflection during cut
• Mill diameter tolerance of +0.00 / -0.02 mm for precise fitment

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill within the OSG Series 3720 product line, compatible with standard tool holders accepting a 0.2362-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC or manual milling equipment. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill from the tool holder. Use an appropriate collet or end mill holder rated for the 0.2362-inch shank diameter and torque the retention fasteners per the tool holder manufacturer specifications. Verify runout after installation before initiating a cut.
