ᐅ Kallax as a Mini Office – Cordless Drill Damages Shelf Panels!

Luix53Hello everyone,
I recently converted a Kallax shelving unit into a small mini office and am generally happy with it. However, while installing the shelves using a cordless drill, I noticed that the screw holes sometimes crack or the wall thickness around the screws gets damaged. The shelf walls are relatively thin and made of coated wood-based material, which apparently isn’t very durable under the stress from the drill.
My question to the community: How can I prevent damage to the shelf walls when screwing them in with a cordless drill? Are there any techniques, precautions, or alternatives to screwing that you would recommend when using a Kallax as a mini office, to firmly secure shelves or panels without damaging the walls?
I appreciate any tips, personal experiences, or construction suggestions!

Hello Luix53,
You have correctly observed that the wooden panels of Kallax are relatively thin and therefore fragile. In addition to pre-drilling, I recommend using a torque-limiting screwdriver or setting a lower torque on your cordless drill. This way, the screw is driven in more gently, reducing the risk of splitting.
Also: Use screws with a fine thread and avoid screws that are too long or thick, as they might penetrate the entire panel.
Have you tried tightening the screws by hand instead of using a cordless drill?

I would like to go into more detail because this topic involves many aspects that are often underestimated.
First, it is important to know that Kallax modules are made from compressed wood material, which has limited load-bearing capacity and durability, especially at the thin side panels. When screwing in with a cordless drill, high local pressure and friction are generated. This easily causes the material fibers around the screw hole to break or tear.
My tips:
1. Always pre-drill to the full length of the screw. The drill bit diameter is crucial: it should match the screw shaft—preferably slightly smaller—without including the threads.
2. Use flat-head screws that distribute pressure well in the material when inserted.
3. Reduce the torque setting on the cordless drill to a level that does not overload the material. It’s best to screw in slowly and turn the last millimeter by hand.
4. If possible, use wood glue or construction adhesive in addition, which increases stability without overloading the panels.
Which screws exactly are you using, and how thick are they? That would be interesting to know.

To add: Pay attention to the screw length as well. For Kallax shelves, short chipboard screws (around 10–15 mm (0.4–0.6 inches)) are often ideal because they cause less stress on the material. Using longer screws increases the risk of splitting.
Additionally, it is advisable not to place screws too close to the edge of the shelf component, as this increases the chance of breakage. Ideally, maintain a distance of at least 2–3 cm (0.8–1.2 inches) from edges.
Regarding the mini office: Did you modify the shelf later, or are those the original shelves? Sometimes additional metal brackets or corner braces, secured with longer screws in more stable positions, can help.

Pre-drill holes before screwing, using a drill bit that is at least as thin as the shaft of the screw. Thanks, I did that, but some splitting still occurred.

Use a torque wrench on the cordless screwdriver or set the torque lower. That was a helpful tip. I used the standard setting. I will try a lower torque level.

Regarding the screws: I’m using original chipboard screws from IKEA, about 16 mm (5/8 inch) long, with large heads. Some are also placed close to the edge, as pikin pointed out.
Should I get shorter screws? Maybe ones with smaller heads? My storage options are currently quite limited.
For the mini office, the shelves are original, but the desk attachment is self-made and mounted on top of the Kallax unit.
