The Build Behind This Item
I marked around the heater mounting plate and drilled the initial cutting access. The reciprocating saw and grinder then helped make the rectangular opening through the floor.
This was an awkward multi-tool job, and the blade breakages made it more frustrating. After the metal was removed, I still had sanding, primer and paint to finish before offering up the heater.
Two Broken Blades During the Floor Cut
- I marked the floor opening from the heater mounting plate.
- I started with a drilled hole and worked with the reciprocating saw and grinder.
- I finished the opening with sanding, primer and paint.
Camper Van Project Applications
Reciprocating-saw blades differ in length and tooth arrangement as well as the material named on the pack. Clearance beyond the cut also matters when the blade moves through its stroke. Steven's capsule-opening account gives the project context for comparing these blades with his jigsaw set.

My Experience with This Tool
By Steven Smith
These are high-quality blades, and I'd recommend them. I used them for the tougher, thicker cuts my jigsaw couldn't handle.
A few of them bent under heavy use. You can bend them back into place and keep cutting, although they'll never be perfectly straight again.
My DEWALT reciprocating saw review explains where I used these blades, including cutting the van siding for my bed capsule openings.

Hi, I'm Steve Smith with Camper Van Freedom. These are my DEWALT D W forty-eight ninety-two reciprocating-saw blades. Two metal-cutting blades broke during an awkward heater-floor opening, but my overall experience with this assortment was still positive. Those two parts of my review explain where it worked for me and where the job got frustrating.
DEWALT identifies the D W forty-eight ninety-two as a twelve-piece bi-metal reciprocating-saw blade set with a telescoping storage case. The assortment includes different blade shapes and sizes for different cutting tasks. The matching set picture and current Amazon buying link are on my full review page below.
I used these blades with my DEWALT D C S three-eighty B reciprocating saw for tougher, thicker cuts that my jigsaw could not handle. That included cutting the van siding for my bed-capsule openings. The saw drives a straight blade back and forth; the matching tool picture keeps the powered saw separate from the replacement blades.
The floor-opening photographs show one specific, awkward job beneath the passenger seat. I marked around the heater mounting plate and drilled the initial cutting access. Two of the metal-cutting blades broke during that floor cut. Completing the opening involved more than the reciprocating saw alone, and the breakages added to the frustration.
The finished opening still needed surface work. I sanded, primed and painted after removing the metal, then offered up the heater. My photographs show the saw at the marked floor and the opening after the cutting and finishing stages. The sequence diagram separates marking, starter access, cutting and finishing so the result is understandable.
My broader review calls these high-quality blades, and I would recommend them. A few bent under heavy use. I could bend them back and keep cutting, although they would never be perfectly straight again. That overall recommendation belongs alongside the two breakages recorded in the floor job, rather than letting either part erase the other.
My page compares the Bosch R A P seven P K mixed assortment and the Diablo D S zero-zero-fourteen S bi-metal set. The Bosch is another mixed blade selection; the Diablo assortment includes six-inch and nine-inch blades. Those matching pictures help compare length, material and assortment. They are researched buying alternatives, not two extra sets I am claiming to have used.
Thanks for watching. I'm Steve Smith with Camper Van Freedom. We covered my DEWALT D W forty-eight ninety-two blades, the floor-cut breakages and why I still recommended the set overall. My full review, actual build pictures, related reciprocating-saw review and current Amazon buying options are linked below. Until next time.

My Takeaway for Choosing the Kit
My experience with this set on this cut was disappointing. For a new assortment, I would compare the blades supplied for the material and the room available around the opening. Bosch RAP7PK is another mixed set; Diablo DS0014S includes six- and nine-inch bi-metal blades. Those assortment and length differences give me concrete alternatives to compare for the next cutting job.
