Value Collection 723-3944 Square End Mill 1-3/4 in 6 Flute

Product Description

The VALUE COLLECTION 723-3944 is a 6-flute square end mill designed for milling operations that demand rigidity and heat resistance. Constructed from M42 cobalt high-speed steel, this single-end tool features a 1.75-inch cutting diameter and a 2-inch length of cut, making it well-suited for slotting, profiling, and peripheral milling in tough workpiece materials. The 30-degree spiral helix angle promotes efficient chip evacuation, while the bright uncoated finish is appropriate for applications where coating interaction with the workpiece is a concern. Licensed machinists and tool-and-die professionals are the primary installers of this tool class.

This end mill is intended for use on vertical machining centers, knee mills, and manual or CNC milling machines where a 3/4-inch shank diameter collet or end mill holder is available. The centercutting geometry allows plunge entry in addition to conventional peripheral and slot cuts. With a regular-length overall dimension of 4.5 inches and right-hand cut with right-hand flute direction, it follows standard tooling conventions for most horizontal and vertical milling setups. No extended reach or coolant-through capability is built into this tool.

Key Features

• M42 cobalt construction for elevated heat and wear resistance compared to standard M2 HSS
• 6-flute design increases feed rates and improves surface finish on finishing passes
• 30-degree helix angle promotes smooth cutting action and efficient chip flow
• Centercutting geometry permits plunge milling in addition to side and slot cuts
• Bright uncoated finish compatible with a wide range of cutting fluids and materials
• Right-hand cut, right-hand flute — standard orientation for most milling machines

Compatibility

Designed for use in any milling machine or machining center equipped with a 3/4-inch diameter end mill holder, collet chuck, or shrink-fit toolholder accepting a straight shank tool.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Secure the shank to the minimum recommended engagement depth in the toolholder to prevent pullout under cutting loads. Verify runout with a dial indicator after clamping before beginning a cut.
