What powertool do I need to use to install countersunk inserts?

The tools CLPTC-1, CLPTC-2 and CLEPT1 are the original tools used for installation in industrial applications.

When the question arose to have a tool that could install inserts at a certain depth, the new nose pieces were designed that could do this:


However, the tool functions in the way that it stops rotating when it reaches the surface of the parent material.

The airmotor of the EPT1 doesn't have enough power, and the pneumatic tool don't have the sensors and aren't "smart".

When installing to have the countersunk, it screws the insert in but then the nose piece sleeve gets too tight to the parent material.

This causes marks on the parent material.

That's why we developed the new tool CLEPT2

It has more options and better sensors.

The better sensors are designed in the way that when you screw in the insert, there's a fast stop, to make sure the tool stops rather quick.

This ensures that there are no more revolutions so the sleeve doesn't get too tight too the parent material, but does have the correct depth.

The motor of the CLEPT2 is also different and stronger than the CLEPT1.

New tool will install with less effort than the old tool.


To summarize, for industrial applications you can use:




with standard nose pieces.

For aerospace applications where you need to install the insert in a certain depth you need:


Special nose piece designed to install the countersink clinserts at a certain depth.
