The Build Behind This Item
The heater location was surrounded by existing van metalwork. I needed an opening in the floor, then room for the hardware that would carry my custom front cover. Having several cutting tools mattered because the work changed as the cover took shape.
I would put the grinder in a fabrication kit with the drill, saw and finishing tools. The photograph below shows the opened seat platform; the later cover photograph shows why the cutting work continued after the first rectangle was finished.
A Grinder for Two Stages of the Seat Work
- I helped cut the rectangular floor opening with the drill and saw.
- I sanded, primed and painted around the opening.
- I returned to the seat platform to cut openings for the cover brackets.
Camper Van Project Applications
Cutting a metal part to length and smoothing its edge are separate operations. The wheel or disc determines the operation, with its size, bore and speed rating needing to suit the grinder. Van brackets, unwanted protrusions and small fabrication pieces make accessory selection especially important.

Manufacturer Specifications And Instructions
| Specification | Manufacturer Detail |
|---|---|
| Model | DCG412B |
| Wheel Format | 4-1/2 to 5 inches |
| Power Platform | DEWALT 20V MAX |
| Package | Tool only |
DEWALT identifies the DCG412B as a cordless grinder in its 4-1/2 to 5-inch range. Grinding wheels and cutting wheels serve different jobs; the wheel type, bore and diameter need to match the particular attachment and operation.
My Experience with This Tool
My DEWALT angle grinder became one of my favorite tools because it could do so many different jobs. I grabbed it when I needed to cut something quickly, grind down sharp metal or protruding screws and nails, level an uneven part, or strip material. I used it on 2020 aluminum extrusion, metal van parts and smaller pieces of wood and plastic. Cutting extrusion this way took more effort than using my miter or circular saw, but I could start without setting up either saw.
During my build I removed the grinder guard and side handle because I found they got in the way of access. That was a risky choice: I had less protection from the wheel and sparks, and sparks could burn my clothes or ignite nearby Thinsulate. I recommend keeping the tool's protections in place. The grinder itself took repeated drops and hard use on the road and still works well.
I built much of the van on the road, carrying tools and materials in a trailer and working outside. Durability is the main reason I consider my DEWALT tools worth the money: they kept working through dirt, travel and rough handling.
My Takeaway for Choosing the Kit
The useful lesson was how often I returned to the grinder as the fitting changed. My choice between another cordless grinder and a corded one would start with the work area and power supply, then the switch arrangement shown in each product card. The linked DCG407B uses a slide switch; the two corded alternatives use paddle switches.
