Value Collection 724-1197 Roughing End Mill 3/4 in Cobalt

Product Description

The VALUE COLLECTION 724-1197 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a TiN coating, this tool handles tough ferrous and non-ferrous materials where standard HSS tooling wears quickly. The 3/4 inch diameter cutter features 4 flutes with a right-hand cutting and right-hand flute direction, a 4.125 inch length of cut, and a 6.375 inch overall length. It is center-cutting, allowing plunge entry as well as peripheral cuts. Machinists and tool-and-die professionals working on manual or CNC mills will find this a reliable workhorse for roughing passes.

This roughing end mill suits general-purpose roughing applications on vertical and horizontal milling machines. The coarse-tooth geometry breaks chips aggressively and reduces chatter on deep cuts in steel, alloy steel, and similar hard metals. The 3/4 inch shank diameter matches standard R8, CAT, BT, and similar collet and end mill holder systems commonly found in job shops and production environments. It is a single-end tool intended for use until the cutting end is worn, then replaced rather than reground in most shop contexts.

Key Features

• M42 cobalt construction for extended tool life in hard and abrasive materials
• TiN coating reduces friction and improves wear resistance at the cutting edge
• 4-flute, right-hand cut and helix for efficient chip evacuation on roughing passes
• Center-cutting design permits direct plunge entry without a pre-drilled hole
• 4.125 inch length of cut accommodates deep pockets and stepped features
• 3/4 inch shank diameter fits common end mill holders and collet chucks

Compatibility

Designed as an OEM-style replacement or standard tooling option for 3/4 inch end mill holders, collet chucks, and milling machine spindles accepting a 3/4 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before seating or removing the tool from the holder. Torque the set screw or collet nut to the holder manufacturer's specification and verify tool runout with a dial indicator before beginning the cut. Inspect the cutting edges for chips or wear before each use and replace the tool when edge condition degrades to avoid workpiece damage or tool breakage.
