Tool choice
Which tool for which task
Details
Drill vs driver
Drill — drilling, driver — fastening; one 18V combo is the optimum for home.
Jigsaw vs circular
Jigsaw — curved & thin, circular — straight & long; the 'universal jigsaw' is a furniture myth.
Grinder vs sander
Grinder — cut/clean rough; random-orbit sander — finish surfaces without grooves.
Hand vs power
Chisel, plane, miter box — joinery precision; power tools — stock-prep speed.
Buy a battery platform (18V) first, not individual tools: batteries are interchangeable, cheaper overall. For joinery, the #2 tool is a miter saw.
