version.
(3) High strength steel tube material is picked and heat-treated to

during welding process
1. Square head following section bold, more solid, not easy to
break
2. Welding: processing all welding two times more durable
3. The first row of the pressure point two holes, more solid, which
greatly reduces the rebound is not easy to break, and the pressure
point is lengthened 500mm, longer and more durable
4. Oblique tooth widening, no longer parallelogram, but symmetry
and pressure points, unlock more convenient, prevention with rod
5. Protective ring, easy to wear point replaced removable
replacement parts, easy to maintain, more wear and increase the
service life of the Kelly bar
6. Driver sets: Our products internal spline to 1 m, longer, more
wearable, and the drive sleeve height 1.2m (other manufacturers
