Hoffman Diamond Pneumatic Core Drill NPC Kor N Seal Model 90539 11690

  For sale is a Hoffman Diamond Pneumatic Core Drill 
NPC Kor N Seal Model 90539

As you can see in the pictures, the wheels still have their 
original paint. In my opinion, I believe this indicates
that this was not used very much.
