Value Collection 724-0146 Roughing End Mill 5/8 in Cobalt

Product Description

The VALUE COLLECTION 724-0146 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 heat and wear resistance suited to tough ferrous and non-ferrous materials. The 4-flute, right-hand cutting geometry with a 0.625 inch diameter removes chips efficiently while reducing chatter during heavy cuts. With a 1.625 inch length of cut and 3.75 inch overall length, it fits standard vertical and horizontal milling setups. Installed by machinists and tool-and-die professionals, this end mill handles roughing passes where cycle time and tool life are the priorities.

This end mill is suited for roughing operations on a wide range of materials including alloy steels, stainless steels, and cast iron where high heat generation would degrade standard HSS tooling. The center-cutting design allows plunge entry as well as peripheral cutting, making it versatile for pocketing and slotting applications. The 0.625 inch straight shank fits standard ER and side-lock collet systems common to CNC machining centers and manual knee mills.

Key Features

• M42 cobalt HSS construction for elevated heat resistance during aggressive roughing cuts
• 4-flute, right-hand helical geometry promotes efficient chip evacuation and reduces chatter
• Center-cutting capable — supports direct plunge entry without a pre-drilled pilot hole
• Bright, uncoated finish provides a consistent surface for easy wear inspection
• Single-end design with 0.625 inch shank diameter matches standard collet and end mill holder bores
• 1.625 inch length of cut accommodates moderate-depth roughing passes in typical milling fixtures

Compatibility

Designed as an OEM-style replacement roughing end mill for use in standard 5/8 inch end mill holders, ER collet chucks, and side-lock tool holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following established shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended engagement depth in the holder and torque the retention screw or collet nut per the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing the cut, as excessive runout accelerates wear and reduces surface quality.
