Value Collection 723-6770 Roughing End Mill 3/4 in Cobalt

Product Description

The VALUE COLLECTION 723-6770 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a TiN coating, it handles tough ferrous and non-ferrous materials with consistent performance. The 4-flute, right-hand cutting configuration with a right-hand flute direction delivers efficient chip evacuation and reduced vibration during roughing passes. With a 3/4 inch mill diameter and 1.625 inch length of cut, this tool suits a range of roughing operations on manual and CNC mills operated by machinists and tool-room professionals.

This roughing end mill is suited for use on knee mills, vertical machining centers, and general-purpose CNC milling machines in job shop, maintenance, and production environments. It is a non-centercutting tool, meaning it is intended for peripheral cutting and side milling rather than plunge cuts. The 3/4 inch shank diameter provides rigid tool holding in standard end mill holders and collet chucks. No extended reach geometry is present, keeping runout low and rigidity high in standard-depth applications.

Key Features

• M42 cobalt construction for heat and wear resistance in tough materials
• TiN coating reduces friction and extends tool life between regrinds
• 4-flute, right-hand cut and right-hand helix for efficient chip removal
• Single-end design with 1.625 inch length of cut and 3.875 inch overall length
• Non-centercutting geometry suited for peripheral and side milling operations
• 3/4 inch shank diameter fits standard end mill holders and collet chucks

Compatibility

Designed as a standard single-end roughing end mill with a 3/4 inch shank, compatible with end mill holders, R8 collets, and similar tooling systems that accept 3/4 inch shank tooling on knee mills and vertical machining centers.

Installation Notes

Installation is performed by a machinist or tooling technician. Power down and lock out the spindle before loading or removing the tool. Seat the shank fully in the holder and torque the drawbar or set screws to the toolholder manufacturer's specification. Confirm runout with a dial indicator before beginning a cut. As a non-centercutting tool, do not use for plunge entry into solid material.
