RTC Mechanical Scraper
 
The main construction features of the RTC makes it possible to maintain the
thickness of the continuous chip constant, even if the pipe is misshaped.
And to adjust the length of the surface to scrape according to the depth
of the coupler.

The RTC 710 features an extendable arm to scrape the exact length of the
coupler, which is an advantage when having to perform maintenance/
repair jobs on the building site. The main chuck has four extendable arms
that clamp directly onto the inside diameter of the pipe.
