The Build Behind This Item
The large piece of metal coming out was only one part of making the opening. I still had cut edges to work over before fitting the front cover and side panels around the heater location.
The REXBETI set belongs in that finishing part of my tool kit. The photograph shows the platform after the cutting work; the file and sandpaper were the hand tools between rough removal and the next fitting step.

Finishing the Cut Seat Platform
- I made the opening with the drill, saw and grinder.
- I worked over the cut edges with a metal file and sandpaper.
- I fitted the front cover and triangular side panels.
Camper Van Project Applications
A file provides controlled removal at a cut edge or small protrusion. Flat, round and other profiles reach different shapes, including drilled holes and corners. Finishing a wire pass-through also means dealing with the edge protection after the metal has been deburred.

REXBETI describes this as a 25-piece kit containing sixteen files and the accompanying accessories. The four larger files have different profiles: flat for a straight edge, round for a curved opening, half-round for flat or curved surfaces, and triangular for corners and grooves. The smaller needle files reach tighter details. In a camper-van build, those shapes are useful for refining cut metal edges, brackets and small openings after drilling or cutting. I used my set on sharp edges around wire routes and other metalwork. My review below also records the files that broke when bent or torqued, alongside why I still considered the inexpensive set a good value.
My Experience with This Tool
I used these files to smooth sharp metal all over the van, especially where wires passed through. Whenever I cut a hole in the van's sheet metal, I filed the edges, and I grabbed the set for any other project where metal needed smoothing.
The files didn't hold up well to bending or twisting. Two of the large files and two of the small ones broke on me, which is the trade-off I found with an inexpensive set.
This set was cheap and genuinely useful for smoothing metal during my build. I'd call it good value for occasional work, not a professional set.

Hi, I'm Steve Smith with Camper Van Freedom. This is my REXBETI metal file set. I used these files to smooth sharp metal throughout the van, especially where wires passed through. They were inexpensive and useful, but some broke when bent or twisted. For me, this was good value for occasional work.
The matching product picture shows larger files and smaller needle files together in their case. Different profiles reach different edge shapes. A flat face, a curved opening and a tight corner do not present the same surface to the tool. The file shape is part of choosing what reaches the remaining metal.
My seat-platform photograph shows the opening after the powered cutting work. I worked over the cut edges with a metal file and sandpaper before fitting the front cover and triangular side panels. The photograph shows that opening. The workshop footage illustrates measuring and holding work around a workpiece.
Cutting out the large piece was one stage; finishing the remaining edges was another. The diagram separates the rough opening, the hand-finishing stage and the later fit. A file gives controlled removal at the edge or protrusion still needing attention after the larger piece has been removed.
My owner review includes both usefulness and breakage. I reached for the set whenever metal needed smoothing, including holes cut in the van's sheet metal. Two of the large files and two of the small ones broke on me when bending or twisting was involved. That was the trade-off I found with this inexpensive set.
The seat opening puts the finishing stage in context. I still had edges to work over before fitting the cover pieces around the heater location. The hand work came between rough removal and fitting. The same distinction helps explain why the file kit remained useful even though its durability disappointed me.
My page compares two researched alternatives. Nicholson emphasizes general-purpose files in several lengths. WORKPRO groups three larger profiles: flat, half-round and round. Their matching pictures show the different assortments. These are comparison options alongside my firsthand REXBETI account, including the files that broke.
Thanks for watching. I'm Steve Smith with Camper Van Freedom. The REXBETI set was useful, inexpensive and good value for my occasional metal finishing, with breakage as part of the ownership story. The full review, seat-opening photograph and current buying options are linked below. Until next time.

My Takeaway for Choosing the Kit
I would put files on the shopping list at the same time as the saw and grinder. The REXBETI mix includes both larger and needle-file profiles. Nicholson emphasizes general-purpose files in several lengths, while WORKPRO reduces the choice to flat, half-round and round larger profiles. The useful choice is the shape and size of the edges still needing work.
