If you are running a 20” Wolfpack Warrior for normal concrete grinding, the first question is simple: what tooling system does this machine normally use?
Based on public equipment listings and compatible tooling references, the 20” Wolfpack Warrior is a 2-head floor grinder that holds 6 tools per machine. In the market, it is commonly matched with Wolfpack / Warrior style magnetic trapezoid grinding shoes. For contractors doing normal concrete grinding, the usual starting point is metal bond tooling rather than coating-removal PCD tools.
For most normal concrete grinding jobs, metal bond tools are the practical choice because the goal is usually to open the slab, improve flatness, remove surface irregularities, and prepare the floor for the next step. If the floor is not a coating-removal job, starting with metal bond tools is usually the cleaner and more economical path.
A common setup for this machine is 6 pieces per set of magnetic trapezoid metal bond tools. The exact bond should match the concrete hardness. In practical terms, soft bond is usually chosen for hard concrete, hard bond for soft concrete, and medium bond for general concrete. This matters because the wrong bond can either glaze over too quickly or wear too fast, which reduces grinding efficiency.
For grit selection, many contractors begin with 16/20 grit or 30/40 grit depending on how aggressive the first cut needs to be. If the slab needs more refinement, they often move to 60/80 grit before deciding whether the floor is stopping there, getting coated, or continuing into a polishing sequence. For polishing preparation, the normal flow is metal bond first, then hybrid transition, then resin polishing pads.
If you are also doing corners and edges with a 4.5” hand grinder, the same decision logic still applies: match the bond to the concrete, and keep the scratch pattern as close as possible to the main machine work. That usually gives a more even result across the full floor.
If you are not sure which option is right, the most useful starting point is to define the job stage clearly. Normal concrete grinding usually falls into one of these three situations: first-cut grinding and flattening, scratch cleanup before coating, or polishing prep before resin. Once that is clear, the tooling choice becomes much easier.
At Monkey King Diamond, we supply metal bond tools, hybrid pads, resin pads, and other concrete floor prep tooling for contractors working on jobs like these. If you use a 20” Wolfpack Warrior and want a practical recommendation, start with your main job type, your concrete hardness, and the grit stage you are trying to reach.
