Value Collection 723-2024 Square End Mill 1/4 in 2 Flute Cobalt

Product Description

The VALUE COLLECTION 723-2024 is a cobalt steel square end mill designed for material removal and contouring in metal cutting applications. This double-end configuration offers two usable ends, extending tool life between changes. The cutter measures 0.25 inches in diameter with a 0.5 inch length of cut and a 3/8 inch shank diameter. Built from M42 cobalt high-speed steel, it handles heat and wear better than standard HSS tooling. The bright uncoated finish is suitable for general-purpose milling where coating is not required. Machinists and tool-and-die professionals install this end mill in manual mills and CNC machining centers for roughing and finishing passes on ferrous and high-temperature materials.

This end mill is rated for use on steel, stainless steel, cast iron, and high-temperature alloys. The 2-flute geometry promotes chip evacuation in tougher, more ductile materials and allows for slotting operations where chip load management is critical. The 30-degree helix angle balances cutting forces and surface finish across the listed workpiece materials. The right-hand cut and right-hand spiral flute direction are standard for conventional and climb milling on most vertical milling setups. The double-end design makes it a practical choice for shops looking to maximize value from each tool.

Key Features

• M42 cobalt high-speed steel construction for improved heat resistance and wear life over standard HSS
• Double-end design provides two cutting ends per tool, reducing per-edge tooling cost
• 2-flute geometry supports slotting and chip clearance in steel and stainless steel
• 30-degree helix angle balances cutting force and finish quality
• Center-cutting capable, allowing plunge entry into workpiece material
• Bright uncoated finish suitable for general-purpose ferrous and high-temp alloy milling

Compatibility

Designed for use on steel, stainless steel, cast iron, and high-temperature alloys in manual and CNC vertical milling applications. Accepts standard 3/8 inch collets or end mill holders. Compatible with workpiece material codes P, M, K, and S as defined by ISO material classification.

Installation Notes

Installation is performed by machinists using a collet chuck or end mill holder sized for a 3/8 inch shank. Ensure the spindle is fully stopped and locked out before inserting or removing the tool. Verify runout after seating in the holder, as excessive runout accelerates edge wear on small-diameter cobalt tooling. Follow machine manufacturer feed and speed recommendations for the workpiece material and tool diameter before beginning any cut.
