Value Collection C3SRH-4806 3/4 in Cobalt End Mill

Product Description

The VALUE COLLECTION C3SRH-4806 is a single-end roughing finishing end mill designed for aggressive material removal followed by a refined surface finish in a single tool. Built from M42 cobalt high-speed steel, it carries a 3/4 inch cutting diameter and a 60-degree helix angle that promotes efficient chip evacuation and reduced cutting forces. With 3 flutes and a square end profile, it handles both roughing passes and light finishing cuts across a range of ferrous and non-ferrous materials. The bright uncoated finish is well suited to applications where coating adhesion or heat buildup is a concern. Machinists and toolroom operators use this end mill in vertical machining centers and manual mills alike.

This end mill is intended for use in standard milling operations requiring a 3/4 inch shank tool. The Weldon flat shank provides positive drive engagement in side-lock holders, reducing the risk of pullout under heavy cuts. With a 1-5/8 inch length of cut and a 3-7/8 inch overall length, it fits comfortably in most standard toolholders without excessive overhang. Right-hand flute direction and right-hand cutting orientation are standard configurations compatible with conventional CNC and manual spindle setups. Center cutting capability allows plunge entry without a pilot hole.

Key Features

• M42 cobalt HSS construction provides increased heat and wear resistance compared to standard M2 HSS
• 60-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Weldon flat shank ensures positive drive engagement and reduces pullout in side-lock holders
• Center cutting design allows direct plunge entry into the workpiece
• 3-flute square end geometry supports both roughing and light finishing in a single tool
• Bright uncoated finish suitable for general-purpose milling without coating-related thermal concerns

Compatibility

Designed as a standard 3/4 inch shank roughing finishing end mill compatible with side-lock and Weldon flat toolholders used in CNC machining centers and manual vertical mills.

Installation Notes

Install in a side-lock or Weldon flat toolholder torqued to the holder manufacturer's specification. Ensure the machine spindle is fully stopped and the control is in an e-stop or lockout state before changing tooling. Verify runout with a dial indicator after seating to confirm proper engagement of the Weldon flat against the set screw. Follow your shop's speeds and feeds data for cobalt HSS end mills at the applicable material hardness.
