We evaluated them all on electricity and accuracy when driving screws or drilling holes of varied dimensions in concrete and Wooden. Ranging in practical experience from occasional DIYers to professional woodworkers, drilling machine we evaluated the drills on battery life, which include components, simplicity of use, ergonomics, and Over-all price. Once the lab assessments, we then evaluated the very long-expression sturdiness and effectiveness of ten of the highest types by screening them in our residences for 2 months.
