Value Collection MT3257944 Square End Mill 11/16 in Solid Carbide

Product Description

The VALUE COLLECTION MT3257944 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. With an 11/16 inch (0.6875 inch) cutting diameter and a 4-flute, right-hand spiral configuration, this tool delivers efficient chip evacuation and a smooth finish on flat surfaces, shoulders, and slots. The 30-degree helix angle balances cutting forces and helps reduce chatter during aggressive passes. Centercutting geometry allows the tool to plunge directly into the workpiece when needed. It is typically installed and operated by machinists and CNC programmers in job shop and production environments.

This end mill suits general-purpose milling applications on manual knee mills and CNC machining centers. The 3/4 inch straight cylindrical shank fits standard collet chucks and end mill holders commonly used in both light-duty and mid-range spindles. With a 1-1/2 inch length of cut and 4 inch overall length, it handles moderate-depth passes without excessive overhang. The bright, uncoated finish makes it appropriate for use with cutting fluids and in applications where coating buildup or heat discoloration needs to be avoided. Typical materials milled include aluminum, mild steel, tool steel, and plastics.

Key Features

• Solid carbide construction using submicron-grade material for hardness and wear resistance
• 4-flute, right-hand spiral design for efficient chip removal and improved surface finish
• 30-degree helix angle reduces cutting forces and chatter on demanding passes
• Centercutting capability allows direct plunge entry into the workpiece
• Bright/uncoated finish suitable for use with cutting fluids across a range of workpiece materials
• Straight cylindrical shank for compatibility with standard collet chucks and end mill holders

Compatibility

Designed as a general-purpose replacement or stock end mill for CNC machining centers and manual milling machines accepting a 3/4 inch straight-cylindrical shank. No specific OEM model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before inserting or removing the tool from the holder. Ensure the shank is seated to the full recommended depth in the collet or end mill holder and that the holder is torqued per the tooling manufacturer's specifications. Inspect the cutting edges for chips or wear before each use, as carbide tools can fail suddenly when edge integrity is compromised.
