Makita FR451DZ Cordless Auto Pack Screwdriver 18V and Case Sold (Battery, Charger, Separately)

Industry-first rechargeable screwdriver compatible with coil-linked screws (as of January 2021, according to Makita). High-speed rotation of 6,000 min-1 achieves tightening speeds equivalent to AC-powered models (compared to Makita). It tightens the screw from start to finish without driving it in, ensuring a secure bond between the board and the underlying structure. The motor only rotates when the button is pressed. This achieves exceptionally low noise and a large work capacity. It reduces unnecessary battery consumption, increasing work capacity and reducing noise. By using the battery adapter BAP18E (sold separately), the battery can be separated and carried around the waist. The main unit is approximately 450g lighter. DC 18V, slide-type Li-ion battery specification. Battery and charger sold separately. Tightening capacity: Coil-type connected screws, screw diameter φ3.5 x 25 mm to φ4.2 x 41 mm, 100 screws per row.
