Osg 414-062508 Square End Mill 1/16 in 4-flute Solid Carbide

Product Description

The OSG 414-062508 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.0625 inch (1/16 inch) cutting diameter and 4-flute spiral geometry, it delivers clean, accurate cuts in a compact stub-length profile. The TiCN (Titanium Carbonitride) coating extends tool life by reducing friction and wear at the cutting edge. Micrograin carbide construction supports rigidity and edge retention during high-speed operations. This end mill is centercutting, allowing direct plunge entry into workpiece material. It is suited for use by machining professionals working in tool rooms, job shops, or production environments requiring small-diameter, fine-detail milling.

The 414-062508 is built for small-feature milling tasks where a standard-length end mill would lack rigidity or clearance. The stub-length design minimizes deflection during cuts in shallow pockets, slots, and contoured surfaces. Applications include mold and die work, aerospace component machining, and precision part fabrication where tight dimensional tolerances are required. The 1/8 inch shank diameter makes it compatible with standard collet chucks and tool holders commonly found in CNC machining centers and manual mills.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating reduces friction and extends tool life in ferrous and non-ferrous materials
• 4-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting capability allows direct plunge cuts without pre-drilling
• Right-hand cut with right-hand flute orientation for standard spindle operation
• Stub length profile minimizes deflection in shallow-depth applications

Compatibility

Designed as an OEM-style replacement and standard fitment for 1/8 inch collet chucks and tool holders on CNC machining centers and manual milling machines requiring a 1/16 inch diameter square end mill.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with CNC or manual milling equipment. Power down and lock out the spindle before loading or unloading the tool from the collet or end mill holder. Ensure the shank is fully seated to the recommended engagement depth in the tool holder before tightening. Verify runout with a dial indicator after installation, as this tool diameter is sensitive to even minor collet or holder concentricity issues.
