Black series metal bonded tooling is soft bond and usually averages in the 8,000 to 10,000 square foot range. They’re available in 6,16, 30/40, 60/80 and 150 grits. This is a traditional trapezoid type tool. With price and production being key points to success, these tools will definitely help you out on your upcoming prep or polish job.
The 30/40 can also do some coating removal but probably won’t be fast enough for some people who have Prep/Master type machines. However, the 30/40 tool does great work on new and old concrete for a good beginning cut. This is also the first step in the CPS NXT floor program that will be rolling out very soon. The 30/40 grit #03 Black Series tool has an aggressive medium grit double bar which is used for first cut on hard concrete or to follow the Black Line 02.
