Dremel Multimax MM422B 3pc 3/4 inch Wood and Metal Flush Cut Blade. 3 pieces per pack. Flush cut blades are used to make precise cuts and plunge cuts. May be used on non-ferrous metals, wood, plastic, drywall and other soft materials. When flush cutting it is important not to force the tool during the plunge cut. Strong tool vibration indicates you are applying too much pressure. To protect a delicate surface while using a flush cut blade, use tape or cardboard to cover it before cutting. Blade life will be limited when cutting screws and nails.
