Thread Chaser 35-130mm Universal Outside Thread & Bolt Tool

A universal outside thread chaser used to restore damaged external threads on larger bolts, rods and similar threaded parts. This thread chaser covers diameters from 35mm to 130mm and is made for re-grooving worn or damaged threads without the need for cutting a completely new thread.

Used for workshop repairs, vehicle maintenance and general servicing jobs where damaged threads can hold up reassembly, it suits mechanics and trade users working on axle tubes, thrust rods, steering rods and other threaded components. When a thread has been knocked, burred or partially flattened, the tool can be attached to an undamaged section first and then worked along to recover the existing thread form. That makes it useful when trying to save original parts rather than replacing them straight away.

The supplied re-grooving inserts cover both right and left hand threads, giving more flexibility when dealing with different fittings. Metric thread pitches listed include 1.0, 1.25, 1.5, 1.75, 2.0, 2.5, 3.0 and 3.5mm, while the imperial inserts cover 4, 5, 6, 7, 7.5, 8, 9, 10, 11, 11.5, 12, 14, 16, 18, 20 and 24 thread pitches. Because it starts from an undamaged thread position, it is a practical option for restoring usable threads during regular maintenance and repair work.
