Osg VG441-7502 Square End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The OSG VG441-7502 is a solid carbide square end mill engineered for high-performance milling in ferrous and non-ferrous materials. With a 0.75 inch mill diameter, a 1.625 inch length of cut, and a TiAlN finish, this end mill is built for demanding cutting environments where heat resistance and edge retention are critical. The micrograin carbide substrate supports tighter tolerances and extended tool life compared to standard grades. Four spiral flutes with a 35-degree helix angle promote efficient chip evacuation and smooth cutting action. This tool is intended for use by machinists and tooling professionals in CNC milling centers and manual machines.

The VG441-7502 is suited for production milling applications in job shops, manufacturing facilities, and toolrooms. Its variable index geometry helps reduce chatter and harmonics during aggressive cuts, making it a practical choice for side milling, slotting, and profiling operations. The 0.75 inch shank diameter and 4 inch overall length fit standard collets and end mill holders common across most vertical and horizontal machining centers. Right-hand cut and right-hand flute configuration is the standard orientation for conventional and climb milling.

Key Features

• 0.75 inch mill diameter with 1.625 inch length of cut for deep-reach milling
• TiAlN finish provides high-temperature oxidation resistance for dry and semi-dry cutting
• Micrograin solid carbide substrate for superior hardness and edge integrity
• 4 spiral flutes with 35-degree helix angle for effective chip evacuation
• Variable index flute spacing reduces vibration and chatter during heavy cuts
• Right-hand cut, right-hand flute with single-end configuration

Compatibility

Designed as a standard-shank solid carbide end mill in the OSG VG441 series, compatible with 3/4 inch collets, end mill holders, and hydraulic chucks used on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's runout and clamping specifications. Ensure the machine spindle and tool holder are clean and free of debris before seating the shank. Confirm proper shank engagement depth and secure clamping torque per the holder manufacturer's guidelines before initiating a cut. Inspect the cutting edges for chips or wear before each use and replace the tool if edge integrity is compromised.
