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. Before repair processing After repair processing After repair processing (enlarged picture)

Assembling method LOCK 【procedure】 ① Insert the parallel drive key into the key groove on the arbor. ② Turn the M4 bolt using a 3 mm hex wrench and firmly tighten the parallel drive key in place.

  • On the opposite side, follow the operation instructions

⑤ ① and ② and firmly tighten the second parallel drive key. ③ Insert the cutting edge portion of the tap onto the pilot diameter of the arbor. ④ (Align the tenon groove of the cutting edge portion of the tap to the parallel drive key on the arbor). ③ 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 ⑥ the cutting load during tapping. ① ② Firmly tighten the M10 center bolt using a 8 mm hex wrench to attach the cutting edge portion of the tap to the arbor. LOCK

  • When exchanging the taps head part, secure the arbor firmly to the vise.
  • When ordering for the first time, please order a set of head and arbor.

【reference】 Tightening torque of taps head fixing screw Socket head cap screw. Tightening torque (N · m） M10 24

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.
