Osg 414-109411 Square End Mill 7/64 in 4 Flute Solid Carbide

Product Description

The OSG 414-109411 is a solid carbide square end mill designed for precise milling operations in ferrous and non-ferrous materials. Built to Series 414 specifications, it features a 7/64 inch (0.1094 inch) cutting diameter, a 7/32 inch length of cut, and a 1/8 inch shank diameter with an overall length of 1-1/2 inches. The TiAlN coating provides heat resistance and extended tool life in demanding cutting environments. With 4 spiral flutes and a 30-degree helix angle, this end mill delivers efficient chip evacuation and smooth cutting action. It is centercutting-capable, allowing direct plunge entry into workpieces. Installed by machinists and toolroom technicians in CNC and manual milling applications.

This end mill is suited for slotting, profiling, and contouring operations in precision machining environments. Its compact 7/64 inch diameter makes it well-suited for fine-detail work, narrow slot cutting, and tight-tolerance features common in mold making, die work, and general precision part production. The right-hand cut and right-hand flute configuration is standard for conventional and climb milling on vertical and horizontal machining centers. The 1/8 inch shank fits standard collet systems widely used in CNC machining centers and manual mills.

Key Features

• Solid carbide construction for rigidity and wear resistance
• TiAlN finish for elevated heat resistance and longer tool life
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge milling
• Right-hand cut and right-hand flute, standard for most milling operations
• Compact 7/64 inch diameter suited for fine-detail and narrow-slot work

Compatibility

Designed as an OEM-style replacement and standard tooling option for 1/8 inch collet systems on CNC machining centers and manual milling machines requiring a 7/64 inch solid carbide square end mill.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully powered down and the machine is in a safe, locked-out state before changing tooling. Seat the 1/8 inch shank fully and evenly in the collet to the recommended engagement depth before tightening. Inspect the cutting edges for chips or damage before each use, as carbide tooling is brittle and should not be used if the cutting edge is compromised.
