The WerkMaster Boss 4-in-1 Ultra Floor System grinds, preps, and polishes concrete, and also sands and refinishes wood in a 14-In. wide footprint. The Boss eliminates the need for hand edging, able to get within 1/8-In. of the wall for a given surface, with added stability thanks to the counter-rotational tool heads. This workhorse machine not only gives professional results for prepping, polishing, and refinishing, it's more flexible than other machines, running off standard 110V outlets, and disassembling into 3 components for ease of transport. Compatible HEPA vacuums from WerkMaster also help to reduce mess and keep the operator safe from dust and debris. The Variable Frequency Drive allows the operator to run, tooling from 400 to 900 RPM, making sure the Boss runs at the right speed for the job. The Boss also uses WerkMaster Plug ‘N Go tooling including 5-In. full plates, so customers can easily install the necessary tooling or sanding pads for their next job.

How The WerkMaster Boss Compares To Other Floor Grinder Options

Flooring contractors and rental operations evaluating concrete grinding and polishing equipment usually face this question: should I get a basic single-head handheld grinder, this WerkMaster Boss 4-in-1 system, or a premium multi-head planetary grinder?

Here's the honest comparison:

Why The WerkMaster Boss Is Worth The Investment

This isn't just a floor grinder, it's a genuine 4-in-1 system that grinds, preps, and polishes concrete while also sanding and refinishing hardwood, decks, and docks, giving flooring contractors and rental operations one machine that covers multiple job types instead of owning separate equipment for each.

The Boss specifically addresses the needs of flooring contractors and rental operations that need edge-to-wall coverage on concrete floors alongside the flexibility to tackle wood refinishing jobs without switching machines.

One Machine, Two Very Different Job Types. Whether the job calls for grinding and polishing a concrete floor or sanding and refinishing solid hardwood, engineered hardwood, decks, or docks, the Boss handles both from the same 14-in. footprint, eliminating the need to own and store separate dedicated machines for each material.

Built To Eliminate Hand Edging

The 14-in. footprint gets within 1/8 in. to the wall, eliminating the labor-intensive hand edging typically required near walls and obstructions

Counter-rotational tool heads add stability during operation, keeping the machine steady across the full working surface

The Variable Frequency Drive adjusts tooling speed from 400 to 900 RPM, dialing in the right speed for the material and job

Engineered For Rental-Ready Flexibility

Running on a standard 110V outlet gives rental customers the flexibility to use the machine on any job site without special power requirements

Disassembling into 3 components makes the Boss easy to transport between jobs or load into a rental fleet vehicle

WerkMaster Plug 'N Go tooling, including 5 in. full plates, simplifies tool changes for rental customers unfamiliar with the machine

Real Savings

A 4-in-1 design eliminates the cost of purchasing separate dedicated concrete and wood-refinishing machines

Eliminating hand edging reduces labor hours on every concrete floor job near walls and obstructions

Compatibility with WerkMaster HEPA vacuums reduces cleanup time and keeps the operator safer from dust exposure

Free shipping and no sales tax through Summit Forge Supply keeps the total cost down compared to buying elsewhere and paying tax and freight separately

The Bottom Line Flooring contractors and rental operations that need to grind, prep, and polish concrete, plus sand and refinish wood, can't afford separate machines for each job type. The WerkMaster Boss is built with counter-rotational heads, a wall-hugging 14-in. footprint, and Plug 'N Go tooling, so it delivers professional results across concrete and wood surfaces from a single, transportable system. For anyone running a diverse flooring business or rental fleet, this is the machine built to handle it all.
