Value Collection 723-4433 Roughing End Mill 3/8 in Cobalt

Product Description

The VALUE COLLECTION 723-4433 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers the heat and wear resistance needed for cutting harder ferrous and non-ferrous materials. The 3-flute geometry with a high helix angle and right-hand cutting and flute direction promotes efficient chip evacuation and reduces vibration during roughing passes. At 0.375 inches in diameter with a 0.75 inch length of cut and a 2.5 inch overall length, this tool fits standard 3/8 inch collet or end mill holders. It is center-cutting, allowing plunge entry into workpieces.

This end mill is suited for roughing operations on a CNC machining center or manual knee mill where fast stock removal is the priority. The cobalt M42 grade construction makes it a practical choice when cutting alloy steels, tool steels, stainless steel, and similar tough materials at elevated spindle speeds. The single-end configuration is standard for general shop use and toolroom work. Machinists and tool-and-die technicians typically use this style of roughing mill before transitioning to a finish end mill to bring parts to final dimension.

Key Features

• M42 cobalt construction provides elevated heat and wear resistance compared to standard M2 HSS
• 3-flute high-helix design promotes rapid chip evacuation during heavy roughing cuts
• Center-cutting geometry allows direct plunge entry without pre-drilled starting holes
• Right-hand cut and right-hand flute direction for use in conventional spindle setups
• Bright uncoated finish maintains sharp edge geometry out of the box
• 3/8 inch shank diameter matches standard collet and end mill holder sizes

Compatibility

Designed as a direct-fit roughing end mill for any milling machine or machining center equipped with a 3/8 inch collet, end mill holder, or Weldon-style tool holder.

Installation Notes

Installation and tool changes should be performed with the machine powered off and the spindle fully stopped. Seat the shank fully into the holder and torque the set screw or collet nut according to the toolholder manufacturer's specification. Inspect the cutting edges for chips or damage before mounting. Follow standard shop safety practices and machine guarding requirements during operation.
