Osg VG441-1006 Square End Mill 1 in 4 Flute Solid Carbide

Product Description

The OSG VG441-1006 is a solid carbide square end mill engineered for high-performance milling in demanding production environments. Built from micrograin carbide and finished with a TiAlN coating, this tool delivers extended wear resistance and thermal stability at elevated cutting speeds. It features a 1-inch cutting diameter, a 2-inch length of cut, and a 5-inch overall length with a 1-inch straight shank. The 35-degree spiral flute geometry and right-hand cut with right-hand flute direction promote efficient chip evacuation and smooth cutting action. Licensed machinists and CNC programmers will find this tool well-suited for aggressive material removal in ferrous and non-ferrous applications.

The VG441-1006 is designed for use in CNC machining centers and manual mills where a full-inch diameter end mill is required. Its centercutting capability allows direct plunge entry into workpieces without pre-drilling. The variable index design reduces harmonic vibration during heavy cuts, making it a practical choice for roughing and semi-finishing operations on steel, stainless steel, cast iron, and similar materials. This tool suits job shops and production floors running medium-to-high-volume work where tool life and repeatability matter.

Key Features

• Micrograin solid carbide substrate for hardness and edge retention
• TiAlN finish provides thermal barrier and oxidation resistance at high cutting speeds
• 35-degree helix angle promotes smooth chip flow and reduced cutting forces
• Variable index flute spacing minimizes chatter and harmonic vibration
• Centercutting geometry allows direct plunge milling without pre-drilling
• Right-hand cut, right-hand flute — standard orientation for conventional and climb milling

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 1-inch straight shank end mill. Part of the OSG VG441 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a properly sized collet or end mill holder torqued to the machine manufacturer's specification before spindle engagement. Verify runout with a dial indicator before cutting. Always power down and lock out the spindle before changing tooling, and confirm the tool is fully seated before resuming operation.
