Value Collection 723-5510 Roughing End Mill 5/16 in Cobalt

Product Description

The VALUE COLLECTION 723-5510 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, this tool handles tough ferrous and non-ferrous workpiece materials where standard HSS tooling falls short. The coarse pitch, 3-flute geometry produces heavy chip loads while reducing chatter and heat buildup during roughing passes. With a 5/16-inch mill diameter, a 3/4-inch length of cut, and a 2-1/2-inch overall length, it fits standard toolholders and is well-suited for shops running manual mills or CNC machining centers that require a reliable roughing solution in smaller diameter ranges.

This end mill is intended for roughing applications where stock needs to be cleared quickly before finishing passes. The right-hand cutting and right-hand flute direction make it compatible with conventional right-hand spindle setups. The 3/8-inch shank diameter accommodates common collet and end mill holder sizes. It is not center-cutting, so plunge milling is not recommended. Machinists, toolroom operators, and production CNC operators working in job shop or manufacturing environments are the primary users of this tool.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• Coarse pitch, 3-flute design promotes aggressive chip evacuation during roughing
• Bright, uncoated finish suitable for a range of common workpiece materials
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• 3/8-inch shank diameter fits widely available collets and end mill holders
• Single-end configuration with 3/4-inch length of cut and 2-1/2-inch overall length

Compatibility

Designed as a standard single-end roughing end mill with a 3/8-inch shank, compatible with right-hand spindle milling machines using collet chucks or end mill holders sized for 3/8-inch shanks.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Secure the shank fully in the collet or end mill holder and torque to the toolholder manufacturer's specification before engaging the spindle. Confirm spindle direction is right-hand before operation. Because this tool is not center-cutting, avoid direct plunge entry into solid material.
