Drill America 2"-12" Carbon Steel Hex Die - DWT Series for Thread Repair & Pipe Fitting in Industrial and DIY Projects

I have an 8ft bush hog I use for shredding thick brush and small trees. The cotter key that held the nut in must have snapped off allowing the washer to wiggle loose and over time buggered up the threads on the gear shaft rendering putting a new washer on, not possible. This die saved me tons of time and effort unbolting and hauling in the gear box to the supplier for a fix. Got the die on and slowly and carefully threaded it down onto the shaft creating new threads. Now my blades and stump jumper are back installed like new!
