Where can buy hilti sf 144 switch - Hilti 3431126 SF 144-A CPC Drill/Driver

I would contact Hilti or a Hilti dealer. Here is a link to their site. You will have to remove any fasteners that hold the housings together so that you can replace the switch.

Hilti

call HILTI direct at 1-800-879-8000 and they can either give you the location of a local service center or buy from them direct. They have excellent customer service people.

Under Hilti, the SF 121 is the battey part number. I would need the tool's part number to know which switch you need. On the bad side, I haven't been able to find a secondary market for Hilti parts, you usually have to buy from them. Hilti's number is (866) 445-8827 if you would like to call them and order the part.

look at this website for parts....

MABE THE TORQ OF THE DRILL IS NOT POWERFULL ENUGH FOR CORE BORE .

It could be the contacts on the switch are burning out. The 92 also had an electronic speed regulator that could be going out.

After you run the drill and it stops. Unplug the drill, take the handle off and apart. Feel the screws on the switch were the wires are connected. If one of them is hot to the touch that usually means the contacts are burning up.

The genuine hilti grease isnt that easy to get. but I have used a stadard lithium grease in the past without any problems.
