Osg VGM7-0053 Square End Mill 3/8 in 7 Flute Carbide

Product Description

The OSG VGM7-0053 is a solid carbide square end mill engineered for high-performance milling in demanding machining environments. Part of the OSG VGM7 series, this tool features a 3/8-inch diameter cutting head, seven helical flutes with a 36-degree helix angle, and an EXO coating that enhances wear resistance and heat dissipation during aggressive cuts. With a 1.5-inch length of cut and 4-inch overall length, it is sized for a wide range of standard milling operations. The variable index geometry reduces chatter and improves surface finish. A licensed machinist or CNC programmer typically selects and runs this tool.

This end mill is suited for ferrous and non-ferrous metal milling where tool life and cut quality are priorities. The 3/8-inch straight cylindrical shank seats directly into standard collets and end mill holders. The single-end, right-hand cutting configuration and micrograin carbide substrate make it appropriate for finish passes and semi-finish passes on steel, stainless, and hardened materials in CNC machining centers and manual mills. It is a regular-length tool, making it practical for most vertical and horizontal milling setups without the deflection risk of extended-reach tooling.

Key Features

• 3/8-inch cutting diameter with seven helical flutes for efficient chip evacuation
• 36-degree helix angle promotes smooth cutting action and reduced cutting forces
• EXO coating improves surface hardness and thermal resistance for extended tool life
• Variable index flute spacing reduces vibration and chatter during high-feed operations
• Micrograin solid carbide substrate provides hardness and toughness across a range of workpiece materials
• Single-end, right-hand cut with straight cylindrical shank for direct collet or end mill holder mounting

Compatibility

Designed as an OEM-style replacement and standard production end mill for use in CNC machining centers and manual mills accepting a 3/8-inch straight cylindrical shank collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. The spindle must be fully stopped and the machine locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention hardware per the toolholder manufacturer specifications. Inspect the cutting edges for chipping before each use and verify runout with a dial indicator after installation.
