Value Collection 723-5798 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The VALUE COLLECTION 723-5798 is a single-end roughing end mill designed for high-material-removal-rate milling operations in metalworking applications. Made from M42 cobalt high-speed steel with a bright, uncoated finish, it measures 1 inch in diameter with a 1.625-inch length of cut and a 4.125-inch overall length. The 5-flute geometry produces a chip-splitting action that reduces cutting forces and vibration compared to standard end mills, making it a practical choice for roughing passes on ferrous and non-ferrous materials. The 1-inch shank diameter provides solid tool holding in standard end mill holders and collet chucks.

This end mill is suited for roughing operations on vertical machining centers, knee mills, and CNC milling machines in job shops, production facilities, and maintenance shops. The right-hand cutting and right-hand flute direction are standard for conventional and climb milling. It is a non-center-cutting tool, meaning it is not intended for plunge cutting — it requires a pre-drilled or pre-bored entry point or a ramping toolpath when entering a pocket.

Key Features

• M42 cobalt steel construction for improved heat and wear resistance over standard M2 HSS
• 5-flute roughing geometry reduces cutting forces and dampens chatter during heavy stock removal
• Bright, uncoated finish — compatible with cutting fluids and suitable for general-purpose roughing
• 1-inch shank diameter matches 1-inch end mill holders and collet chucks without adapters
• Right-hand cut, right-hand helix — standard orientation for most milling setups
• Single-end configuration — full shank length available for tool holding depth

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard 1-inch end mill holders and collet systems on vertical and horizontal milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing tooling. Seat the shank fully into the holder to the recommended engagement depth and torque the drawbar or set screws per the tool holder manufacturer specifications. Because this is a non-center-cutting end mill, do not use it for direct plunge entry into solid material.
