Extension Tube Wrench

Extension tube from ER M type nut to Hexagon for safe tool change:

• The extension tube fits into the ER M nut slots and covers the cutting tool during the tool change process
  preventing possible injury.
• The hexagon of the extension tube allows the operator to place the wrench and apply the necessary force
  to fasten/unfasten the ER M nut safely, minimizing the possibility of the wrench coming loose and
  eliminating the rounding of the edges of the nut. It even allows the use of torque wrenches.
• There are different extension tube lengths to completely cover the tools mounted in the ER tool holder,
  however, if necessary, it can be used with longer tools.

Material: Blued steel.
