It’s best to avoid using an impact drill for drywall because it can pierce through the paper layer and damage it. While this tool can make the job easier, it is important to remember that this type of drill can also cause damage if used improperly.
For one thing, impact drills are designed to work with fast-moving bits, which are not ideal for this type of material. Additionally, the rapid reverse motion used in an impact drill can actually break the thin pieces of drywall and weaken them over time.
Avoiding using an impact drill when working with drywall is best to protect your walls and ensure a strong result. Instead, try simpler hand tools or specialized wall anchors that provide extra support while still allowing you to control the speed of the drilling process.
