Value Collection 723-8698 Square End Mill 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-8698 is a cobalt square end mill designed for milling, slotting, and profiling operations on a range of ferrous and non-ferrous materials. Built from M42 cobalt high-speed steel, it delivers improved heat and wear resistance compared to standard HSS tooling. The cutter measures 0.7874 inches in diameter with a 1.875-inch length of cut, a 0.75-inch shank diameter, and a 4.125-inch overall length. Four spiral flutes at a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The bright uncoated finish suits general-purpose applications where coating is not required.

This end mill is suited for manual mills, CNC machining centers, and knee mills used in job shops, maintenance departments, and production environments. The centercutting geometry allows the tool to plunge directly into material, enabling both peripheral and end cutting in a single setup. Single-end construction with a right-hand cut and right-hand flute direction follows standard milling conventions, making it a direct fit for most tool holders and collet systems using a 0.75-inch bore.

Key Features

• M42 cobalt construction for increased heat resistance and tool life versus standard HSS
• Centercutting design allows direct plunge entry into workpiece material
• 30-degree helix angle promotes smooth chip flow and reduces cutting pressure
• Bright uncoated finish for general-purpose use across a broad range of materials
• Right-hand cut and right-hand flute direction compatible with standard milling setups
• Regular length series suitable for most standard-reach milling applications

Compatibility

Designed as a general-purpose replacement or standard square end mill for use in any milling machine or machining center equipped with a 0.75-inch collet, end mill holder, or Weldon shank holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully and evenly in the collet or holder to the recommended engagement depth to prevent runout and tool pullout during cutting. Verify tool runout with a dial indicator before beginning a production cut.
