Osg 414-0938 Square End Mill 3/32 in 4 Flute Solid Carbide

Product Description

The OSG 414-0938 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide, it delivers consistent cutting performance at small diameters. It features a 3/32 inch cutting diameter, a 3/16 inch length of cut, and a 1/8 inch shank diameter with a 1-1/2 inch overall length. The four-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. This stub-length end mill is center-cutting, allowing direct plunge entry into workpiece material. It is installed and operated by machinists and CNC programmers in job shop and production environments.

This end mill is suited for profiling, slotting, and light pocketing operations in ferrous and non-ferrous materials where a small-diameter tool is required. The stub length geometry provides added rigidity at the 3/32 inch diameter, making it appropriate for close-tolerance work in confined features. It is compatible with standard 1/8 inch collets and tool holders used on CNC machining centers and manual milling machines. No coating is applied, keeping the tool ready for use in applications where base carbide performance is sufficient or where a specific coating will be applied by the end user.

Key Features

• Micrograin solid carbide construction for wear resistance at small diameters
• Four flutes with right-hand cut and right-hand spiral flute direction
• 30-degree helix angle for efficient chip flow and reduced cutting force
• Center-cutting design allows direct plunge milling without a pre-drilled entry hole
• Stub length body increases rigidity and reduces deflection at 3/32 inch diameter
• Uncoated finish suitable for a wide range of base machining applications

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 1/8 inch collet systems on CNC machining centers and manual mills requiring a 3/32 inch cutting diameter tool.

Installation Notes

This end mill is installed by machinists using a 1/8 inch precision collet or tool holder; ensure the collet bore and shank diameter are matched before tightening. Verify runout with a dial indicator before beginning cuts, as small-diameter carbide tools are sensitive to excessive runout. Do not over-torque the collet nut, as this can distort the collet bore and damage the shank. Follow machine tool manufacturer guidelines and applicable shop safety procedures when changing tooling.
