Product Features

  • Main application: repair of screw threads. Removal of burrs, rust, paint or spattering during welding operation.
  • Utilizing the best cutting edge shape for manual repairing of large diameter threads.
  • By simply exchanging the tap's head portion, it is possible to repair M50 〜 M80 threads using the same arbor and it's very economical.
  • By using a long type of arbor, you can repair threads deep in a hole.

on the arbor).
④ Set the flat washer and the spring washer in the countersink of the cutting edge portion.
⑤ Lightly tighten the M10 center bolt with a 8 mm hex wrench.
⑥ Rotate the cutting edge portion of the tap toward the parallel drive key like that of

【reference】

Tightening torque of taps head fixing screw

 

Note:
・ Because of the tap's head replacement method, normal tapping to produce internal thread can not be performed.
Be careful as there is a risk of breakage if an excess torque is imposed on the tap.
・The RE-HT is designed to be used by hand, it can not be used on machines.
・Excessive tightening of hexagon socket head bolts may cause deformation or breakage.
