The Item in My Kit
I bought ZORUNNA Countersink and Plug-Cutter Set as part of my camper van equipment.
The heater-cover work made fastener position and head shape very noticeable. One angled screw left an unsightly hole in the front panel that I planned to cover with a larger washer.
Why the Cover Made Hole Finishing and Access Noticeable
- I made the black cover with a front panel and two triangular sides.
- I joined and fitted it with brackets and self-tapping screws.
- An awkward angled screw position left a hole that I planned to cover with a larger washer.


My Experience With This Tool
By Steven Smith
I mainly used this set for the step drill bits, and they alone made the inexpensive kit worthwhile for me. Individual step bits online and in hardware stores often seemed expensive by comparison.
The step bits worked very well on the metal I used, provided it was not too thick. I used them to make the starter holes for the bed-capsule openings in the side of the van, before cutting out the panels with the jigsaw and reciprocating saw. I liked being able to work gradually through the steps and choose the hole size.
The countersink drill bits were a different story. Their small drill portions were flimsy and brittle, and I think I broke all seven. The retaining nuts did not hold well either: the drill and the base of the bit kept coming apart during use.
The included punch was decent, but I preferred my Mayhew 62215 center punches. They felt much more solid and stable when I struck them against metal; the punch in this kit moved around more.
I did not use the other cutters and accessories, so I have no experience of how those performed. I generally prefer working with metal rather than wood and may not end up using them.
The case fell apart and its latches came off while I was travelling. It had been packed and unpacked repeatedly and knocked around in the trailer, so I attribute that damage to the rough handling. I would expect it to fare better kept in one place.
I would recommend this kit for the step drill bits alone, despite my poor experience with the countersink drills.

Hi, I'm Steve Smith with Camper Van Freedom. This is my ZORUNNA countersink and plug-cutter kit. I would recommend it for the step drill bits alone. Those were good value for me, but the countersink drills were flimsy and brittle, and I think I broke all seven. The different parts of this kit left me with very different impressions.
I mainly used the step drill bits on metal that was not too thick. They worked very well for making starter holes in the side of the van for the bed-capsule openings. I liked working gradually through the steps to choose the hole size. After those starter holes, my DEWALT jigsaw and DEWALT reciprocating saw were the tools for cutting out the larger panels.
The countersink drill bits were a different story. The small drill portions were cheap, flimsy and brittle in my use. I think I broke all seven. The retaining nuts also failed to hold well, and the drill and the base of the bit kept coming apart. Those failures are why my recommendation is specifically for the step bits.
The included punch was decent, but I preferred my Mayhew six-two-two-one-five center punches from Amazon. The matching Mayhew picture shows that separate set. They felt more solid and stable when I struck them against metal, while the punch in this kit moved around more. A center punch marks a starting location; the drill bit then makes the hole.
My heater-cover photographs show why hole position and visible fixings mattered elsewhere in the build. An awkward angled screw left an unsightly hole in the front panel that I planned to cover with a larger washer. The pictures show the actual black cover and vent layout. The workshop footage illustrates measuring and holding a workpiece alongside that fitting context.
I did not use the other cutters and accessories, so I have no experience of their performance. The case fell apart and its latches came off while I was travelling. It had been packed, unpacked and knocked around in the trailer, so I attribute that damage to rough handling. I would expect it to fare better kept in one place.
My page compares the Snappy countersink set and the DEWALT D W thirteen sixty-one drill-bit set. Snappy is a researched countersinking alternative. The DEWALT set is another one I used and reviewed for basic drilling. These are different assortments and operations; the matching pictures keep those distinctions separate from my experience with the ZORUNNA step bits.
Thanks for watching. I'm Steve Smith with Camper Van Freedom. This was my ZORUNNA kit review: good step bits, poor countersink drills, a punch comparison and other cutters I did not use.
