JUNK SUBS
Application
Junk Subs, which are normally run just above the drill bit, have a cup for catching objects too heavy to be completely circulated out of the hole. This is particularly advantageous in milling operations. By running a Junk Sub above a scraper, operators can get quicker, cleaner scraping jobs.
Construction
Junk Subs are constructed from high quality steel, completely stress-relieved after cup and rib guides have been welded to the main body. Rib guides prevent the cup from becoming crushed and help guide the tool through tight places upon withdrawal from the hole. Junk Subs are available in standard, long and extra-long types.
