Osg 3133020 Square End Mill 0.0787 in 2 Flute Solid Carbide

Product Description

The OSG 3133020 is a solid carbide square end mill designed for precise milling operations in metalworking and machining environments. With a 0.0787-inch cutting diameter and a 0.1181-inch length of cut, this end mill is built for small-feature work requiring tight tolerances and clean edge geometry. The WXL coating improves wear resistance and surface finish performance across a range of materials. A 30-degree helix angle promotes efficient chip evacuation and reduced cutting forces. This tool is used by machinists and tool-and-die professionals on CNC mills and machining centers.

This end mill is suited for slotting, profiling, and contouring in precision machining applications. The 0.1575-inch shank diameter fits standard collet chucks and end mill holders used on vertical and horizontal machining centers. The extended reach design and 20 mm reach length make it appropriate for applications where standard-reach tools cannot access the feature geometry. It is a single-end tool with right-hand cut and right-hand flute direction.

Key Features

• 0.0787-inch cutting diameter for small-feature and detail milling
• Solid carbide micrograin construction for rigidity and edge retention
• WXL coating for improved wear resistance and extended tool life
• 30-degree helix angle for efficient chip evacuation
• Center cutting capability allows plunge entry
• Extended reach with 20 mm reach length for deep-feature access

Compatibility

Designed as an OEM-style replacement end mill compatible with standard collet and end mill holder systems accepting a 0.1575-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before tool changes. Seat the shank fully in the collet or holder to the recommended engagement depth before tightening. Verify runout with a dial indicator after securing the tool, particularly given the small diameter of this end mill.
