This reamer (called a bridge reamer) is used when flipping 1 ton TRE (tie rod ends), to open knuckles to 7/8″ when using a tapered sleeve. This style of reamer will make quick work of the job, and we suggest using one over a standard drill bit for a more accurate, quicker process.
Dave –
Just buy this – don’t use a drill bit! This thing cuts knuckles like butter – just use lots of lube and go slow! Drilling with a normal bit is a DISASTER and you’ll just break one or two while cussing at it the whole time. This is much easier, and cheaper than buying multiple 7/8″ drill bits.
