Value Collection MT3258040 Square End Mill 5/8 in Carbide

Product Description

The VALUE COLLECTION MT3258040 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. Built from submicron-grade carbide, this 2-flute tool measures 5/8 inches in diameter with a 1-1/4 inch length of cut and a 3-1/2 inch overall length. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. A bright, uncoated finish makes the tool suitable for applications where coating compatibility or regrinding is a consideration. Centercutting capability allows for direct plunging into workpieces without a pre-drilled pilot hole.

This end mill is used in CNC machining centers, knee mills, and manual milling machines across general-purpose metalworking, tool-and-die, and precision fabrication environments. The 5/8 inch shank diameter provides solid tool holding in standard collets and end mill holders. Right-hand cutting and right-hand flute direction conform to conventional milling setups. The 2-flute configuration offers generous chip clearance, making it particularly effective in slotting and pocketing operations where material removal rates matter.

Key Features

• Submicron-grade solid carbide construction for rigidity and wear resistance
• 2-flute design with spiral flute type for efficient chip clearance in slots and pockets
• 30-degree helix angle for smooth cutting action and reduced cutting forces
• Centercutting geometry allows direct plunge entry without a pilot hole
• Bright, uncoated finish suitable for regrinding and dry or lubricated cutting
• Right-hand cut, right-hand helix for compatibility with standard spindle configurations

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 5/8 inch collets and end mill holders used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the milling machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or tool holder to the recommended grip length, and torque the retention nut to the tool holder specification. Verify runout with a dial indicator before beginning any cut.
