  • TypeHole, Drill, Bore & Wire Gauges
  • Cobalt construction withstands high heat during heavy roughing cuts
  • TiCN coating reduces friction and extends tool life in steel
  • Four-flute design removes material quickly while maintaining finish quality
  • 30-degree helix angle promotes smooth chip evacuation
  • Square end with zero corner radius creates precise flat-bottom pockets

Cobalt Roughing End Mill for General Milling

This 1/2 inch diameter cobalt end mill is designed for roughing operations in general-purpose milling. The four-flute configuration with a 30-degree helix angle supports efficient material removal across a range of workpiece materials. A TiCN finish adds surface hardness and wear resistance for extended tool life in production environments.

Square-End Geometry with 1/2 Inch Shank

The tool features a square-end profile with zero corner radius and a 1-1/4 inch length of cut for creating flat-bottomed pockets and shoulders. A matching 1/2 inch shank diameter fits directly into standard collets and end mill holders without requiring reduction sleeves. The 3-1/4 inch overall length provides adequate reach for typical milling depths while maintaining rigidity.

Verify Machine Capacity and Workpiece Requirements

Confirm that your milling machine or CNC spindle accommodates a 1/2 inch shank and can deliver appropriate speeds and feeds for cobalt tooling. The right-hand cutting direction suits conventional milling setups; ensure your spindle rotation matches this orientation. This end mill is intended for roughing passes; finishing operations will require a separate tool.

Questions about this item

What does the 30-degree helix angle mean for chip evacuation on this roughing end mill?

The 30-degree helix angle provides a balance between chip lifting and edge strength, helping move chips up and out of the cut during roughing operations in steel and tough alloys.

What holder or collet size matches the 1/2-inch shank diameter of this tool?

Use a 1/2-inch end mill holder, ER collet, or shrink-fit chuck with a 1/2-inch bore; the shank is a standard fractional size for direct clamping.

How do I install this end mill so the 1-1/4-inch length of cut is fully usable?

Clamp the shank deep enough that the full flute length clears the holder face, then indicate runout at the tip before cutting to avoid vibration and premature wear.
