Came in an Irwin package. Used it this morning to cut 1.5 inch thread and it worked great! Patience is required when threading, be sure to unscrew it if it starts to turn difficult and don't forget to lubricate it as you work. Never overfill oil.
Pros
Package Dimensions: 1/2" (L) x 2 3/4" (W) x 1/2" (H)
