A tool holder is a machining component that holds the end mill in place. Its purpose is to hold the tool in place as precisely and firmly as possible, as a barely perceptible increase in runout can ruin your project or break your cutting tool.

Different types of holders have varying levels of runout and balance. There is also variation in their lifespans and durability. Another important factor to consider when picking a CNC tool holder is the time it takes to change end mills, as it directly impacts your bottom line.


Tool holders vary based on the method used to hold the end mill in place. Here is a basic overview of the CNC milling tool holder types we offer:

  • Shrink fit holders: This type of holder uses heating and cooling to apply clamping force to the cutting tool. Shrink fit holders offer powerful grip and can dramatically extend tool life.
  • Collet chucks: A collet chuck grips the end mill with a slotted collar. Standard collets are sized by millimeter, and they can be customized as well.
  • End mill holders: These parts use a set screw to secure the cutting tool. They have small nose diameters and are available in a variety of lengths.
  • Tap holders: This category includes rigid, floating, and cartridge-style tap holders. Adapters are also available so you can use more tools on the same holder.
