Hello everyone,
I recently bought a KALLAX shelving unit from IKEA and now want to drill holes in the panels to, for example, run cables or attach brackets. However, I noticed that the panels tend to chip or splinter quite easily when drilling, which obviously doesn’t look good and could also affect stability.
My question is: What is the best way to drill into the KALLAX panels without causing splintering? I assume the material of the panels plays a role – it seems to be some kind of particleboard or similar with a thin laminate layer.
Are there any specific drilling techniques, drill bits, or pre-treatments you would recommend? Would pre-drilling or certain drill speeds help to achieve a clean hole?
I would like to know exactly how to prevent damage so the appearance of the shelving unit stays intact.
Thanks in advance for your experience and tips!

Hello nonix,
I completely understand your concern. KALLAX material is usually made of medium-density fiberboard (MDF) or particleboard with a thin melamine coating. Drilling can easily cause chipping, especially if you start directly with a large drill bit without preparation.
Here are some tips to achieve clean holes:
- Use a sharp wood drill bit, preferably with a center point, to ensure precise positioning.
- Drill at a low speed (maximum 800–1000 rpm) to avoid overheating and splintering.
- To protect the surface, place a piece of painter’s tape or masking tape over the drilling spot. This stabilizes the laminate and prevents chipping.
- When using a larger drill bit, drill a small pilot hole first, then the final hole.
- If possible, drill from both sides—start from the front side nearly through, then finish from the rear side to avoid surface tear-out.
These methods are well proven in furniture construction, especially with thin coatings.
If you’re planning additional loads, you might also consider using inexpensive metal inserts or spacer sleeves to relieve stress on the material.
I hope this helps! If you like, I can also recommend suitable drill bits.

Drill the hole at a low speed (maximum 800-1000 rpm)This is a very important tip. MDF or particleboard tends to splinter badly at high speeds because the drill bit cuts through the material too quickly.
I would like to add the following:
- Use a so-called Forstner bit or a flat wood bit, as they have a clean cutting edge and cause less splintering.
- If you prefer regular drill bits for general materials, always choose one with a sharp, clean edge—ideally a new bit.
- Maintaining a clean work area and firmly securing the board prevents unnecessary vibrations that promote splintering.
- Clamps or vises can be very helpful here.
- Make sure not to apply too much pressure while drilling; let the drill bit do the cutting.
A methodical approach is crucial to minimize splitting. By following these points, you should achieve significantly better results.

The material is simply not designed to handle stress around drilled holes. If you want to create openings for cable pass-throughs, in my opinion there are better solutions than drilling directly into the panels.
For example:
- Attach cable channels to the back and cut openings there
- Use cable ties or terminal blocks instead of heavy-duty fasteners

If you really want to drill, then:
- I recommend a jigsaw with a fine blade for larger cutouts
- Or a minimal pilot hole as preparation
Ultimately, splintering is a technical issue, but it’s also a result of IKEA’s choice of material. I hardly believe that a “perfect” drilling result can be achieved when the material is so thin and laminated.
So it’s worth considering how to find practical solutions without unnecessarily damaging the material.
