Value Collection MT3257956 Square End Mill 7/8 in 4 Flute

Product Description

The VALUE COLLECTION MT3257956 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard material applications. With a 7/8 inch mill diameter and 4-flute geometry, this tool delivers efficient chip evacuation and a quality surface finish. The 30-degree right-hand helix angle promotes smooth cutting action and reduces chatter during full-depth passes. At 4 inches overall length with a 1-1/2 inch length of cut, this centercutting end mill can plunge directly into the workpiece, making it suitable for slotting, profiling, and pocket milling. Machinists and tooling professionals rely on this geometry for demanding production environments.

This end mill is suited for use in manual mills, CNC machining centers, and knee mills where consistent tool geometry and material removal rates are required. The bright uncoated finish makes it well-suited for applications where coating adhesion could present issues or where re-sharpening is planned. Its straight cylindrical shank fits standard collets and end mill holders across common tooling systems. Typical applications include contouring, face milling, and slot cutting in steel, aluminum, and similar workpiece materials at the discretion of the machinist based on speeds and feeds for the specific setup.

Key Features

• Solid carbide construction with submicron material grade for rigidity and wear resistance
• 4-flute spiral flute design for improved surface finish and efficient chip removal
• 30-degree right-hand helix angle reduces cutting forces and vibration
• Centercutting capability allows direct plunge entry into the workpiece
• Bright uncoated finish suitable for re-sharpening and non-coated applications
• Straight cylindrical shank for compatibility with standard collets and tool holders

Compatibility

Designed as an OEM-style replacement and standard tooling option for milling machines accepting a 7/8 inch straight cylindrical shank end mill holder or collet.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and all motion fully stopped. Ensure the collet or tool holder is clean and free of debris before seating the shank to the correct engagement depth. Torque the collet nut or set screw according to the tool holder manufacturer specifications. Always verify runout with a dial indicator before engaging the cut and set speeds and feeds appropriate to the workpiece material and machine rigidity.
