Today's offering is a used pipe tap. I do not see a brand stamped on it, though it does have 'GH4' stamped on it. The drive shaft measures approximately 3/4 inch across, while the tap width is approximately 1 inch. The tap is approximately 5 3/4 inches long total length. It is in fair condition, overall. Please ask questions! No additional accessories are included; what you see in the pictures is what you will get! We are happy to combine shipping whenever possible if you win or buy multiple items. Thanks for your interest!
