Well Bore Clean Tools Junk Sub For Oil Well Drilling Fishing Tools
Junk Sub is the component of well bore clean tools. The junk sub is normally run just above the drill bit which has a cup for catching object too heavy to be completely circulated out of the hole. This is particularly advantageous in junk milling operations.By running a Junk Sub above a Scraper, operators can get quicker, cleaner scraping jobs. Junk Sub is constructed from high quality steel, and features a rib guide which prevents the cup from becoming crushed and helps guide the tool through tight places upon withdrawal from the hole.
