Value Collection 723-4113 Square End Mill 9/16 in Cobalt 4 Flute

Product Description

The VALUE COLLECTION 723-4113 is a cobalt square end mill designed for milling, slotting, and profiling operations on ferrous and non-ferrous metals. Built from M42 cobalt high-speed steel, it offers improved heat and wear resistance compared to standard HSS tooling, making it suitable for harder workpiece materials and higher cutting temperatures. The double-end configuration provides two usable cutting ends, extending tool life between replacements. With a 9/16-inch cutting diameter, a 1-3/8-inch length of cut, and a 30-degree helix angle, this end mill suits general-purpose machining in manual mills and CNC machining centers. It is center-cutting, allowing direct plunge entry into the workpiece.

This end mill is appropriate for job shops, tool rooms, and production machining environments handling steel, stainless, cast iron, aluminum, and similar materials. The bright, uncoated finish makes it a practical choice for applications where a coated tool is not required, or where re-sharpening is planned. The right-hand cut and right-hand spiral flute direction are standard for conventional milling machine setups. Machinists, CNC operators, and tool room technicians will find it suited to both roughing and finishing passes within its rated depth of cut.

Key Features

• M42 cobalt high-speed steel construction for elevated heat resistance and durability in harder materials
• Double-end design delivers two cutting ends per tool, reducing per-edge tooling cost
• Center-cutting geometry allows direct plunge milling without pre-drilling
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Bright, uncoated finish compatible with re-sharpening and general-purpose applications
• Right-hand cut and right-hand spiral for standard milling machine compatibility

Compatibility

Designed as a general-purpose replacement or production end mill for manual knee mills, CNC vertical machining centers, and similar equipment accepting a 5/8-inch straight shank. Verify spindle collet or end mill holder clearance before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully powered down and locked before inserting or removing the tool from the holder. Secure the 5/8-inch shank in a properly sized collet, end mill holder, or Weldon-style holder and verify runout before cutting. Do not exceed the rated length of cut when programming depth of pass.
