The Step Rombo is the worlds best diamond tool as it combines and improves upon the worlds 2 best diamond tool segment designs, that delivers unbeatable ride and cutting performance. The Step segment shape has already taken the local Australian market by storm, with its many serrated cutting edges, it has proven to be one of the best and most effective designs for removing coatings and exposing stone in hard concrete floors, however experienced flooring professionals acknowledge that it suffers from a few serious design flaws being that it can at times be " too aggressive or can excessively gouge a soft concrete or timber floor, cause medium to large planetary grinders to trip out the electrical overload switch of the grinder or power board as a result of too much weight and friction [this often results in a day off and an urgent visit to your highly paid electrical repair man], or similarly worse scrubs out $315 and 9 diamond shoes after only 1 hours work.  Hence experienced and frugal operators have learned too combine and intersperse these very effective step cutting shoes in between harder wearing sacrificial single of double segment diamond grinding shoes, which on large grinding machines is good enough,  but on lighter grinding equipment this combination with regular segments has been proven to be Not Sacrificial enough to be sufficiently effective or productive.  The Grandmaster Step Rombo product range has gone the next evolutionary step and solves all these problems and not only provides a superior sacrificial diamond segment tool combination, but a superior spring plate attachment means for light to medium grinders and floor buffer plates. And a superior diamond  range for large grinders.
