Chicago Pneumatic CP9361 Industrial Air Scribe Engraving Pen & Precision Chisel Hammer

Great Customer Service!!! I purchased 14 of these for my shop and my Techs love the tool. Super easy to setup and use. Seller was awesome when we had a problem with one of the items. They shipped replacement right away so we were not down at all.

Excellent tool. I bought this to work on hard limestone rock to extract fossils. I did have to buy a bigger compressor, a 2.2CFM at 90PSI, 8 gallon capacity. It runs maybe every 90 seconds or so while using this tool turned up to 3-4.It’s been error free and I’ve used the same carbide tip for over a year now. It may not start impacting when I first turn it on, but you simply have to tap the tip on something ever so lightly and it will start up.The tool can be set from 1-5. I typically use it at 4 for heavy work, and 2 for more delicate situations.

Couldn't open the unit to change the bit, stylus, now Ihave to wait 30 days to get my money back!

Smooth and precise.

Just received mine, plugged it in to an airline.... NOTHING!!! Then a few moments later it started when the compressor kicked on only to stop after about 4 seconds of running. Can't get it started again, no clue. No trouble shooting info online I can find. It's Friday after CP has closed and I'm not a happy customer!Took the tool apart following the CP YouTube maintenance guide: https://www.youtube.com/watch?v=hq2PmTtbzdg The piston to cylinder fit felt rough and a little too tight to me so I honed the piston a little using a drill to spin it and some 400 grit sand paper. After that it's been working pretty good, although I think it still seems a little too tight or rough as it still tends to stall, so I should probably hone it some more. The cylinder housing pin is difficult to remove as I had to clamp it to my welding table, shim all my supports so as to ensure that all the energy I applied to strike and remove the spring pin was applied effectively. It actually ought to hone itself in the cylinder, you'd think, if one could get it running for a while.
