Osg 3174025 Square End Mill 0.1181 in 4 Flute Solid Carbide

Product Description

The OSG 3174025 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 0.1181 inch cutting diameter and four flutes ground from micrograin carbide, this tool delivers consistent performance in tight-tolerance applications. The WXL coating provides enhanced wear resistance and surface finish quality. A 35-degree helix angle promotes smooth chip evacuation and reduced cutting forces. This end mill is a single-end, center-cutting tool and is installed and used by machinists and toolroom technicians on CNC machining centers and manual mills.

This end mill is suited for profiling, slotting, and peripheral milling operations where a small-diameter, extended-reach tool is required. The 0.1772 inch length of cut and 25 mm reach length make it effective for working in deep or restricted pockets. The 0.2362 inch shank diameter is compatible with standard collet and end mill holders found on vertical machining centers and multi-axis CNC platforms. Applications typically include die and mold work, aerospace components, and precision part production where micrograin carbide and WXL coating are specified for tool life.

Key Features

• Solid micrograin carbide construction for extended tool life in demanding materials
• WXL coating provides improved wear resistance and thermal protection
• 35-degree helix angle for efficient chip evacuation and reduced cutting forces
• Center-cutting geometry allows direct plunge entry
• Extended reach design with 25 mm reach length for deep pocket access
• Right-hand cut and right-hand flute configuration for standard spindle compatibility

Compatibility

Designed as an OEM-style solid carbide square end mill suitable for standard collet chucks and end mill holders accepting a 0.2362 inch shank diameter.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning cuts, as excessive runout will reduce tool life and surface finish quality on a small-diameter end mill.
