Each tool is an excellent addition to beginner or more advanced toolkits, allowing you to tackle everything from hanging pictures to tile work. You can even use the oscillating tool for precision sanding or removing old flooring adhesive. The 1/2-inch hammer drill has dual speed settings for precision work and kickback protection to reduce the risk of getting hurt if your drill bit binds up. It also has a Rapid Mode Selector so you can quickly switch between hammering, drilling, and driving without adjusting the clutch. The Bosch 4-amp oscillating tool is perfect for flooring projects like tile, laminate, and hardwood, or installing baseboards. The offset blade allows you to cut close to the floor for precision work like re-grouting or replacing broken tiles. It's also ideal for crown molding and cutting drywall for electrical fittings. A Bosch reciprocating saw is great for cutting both wood and metal, provided you're using the appropriate blades. It features a variable-speed trigger for safer starting cuts and dual speed settings for wood and metal, so you'll be able to quickly and safely cut through crates, old wall frames, and copper plumbing. The Bosch X-Lock 4.5-inch angle grinder is meant for working with metal, stone, and tile. The tool-free disc swap system lets you quickly switch out grinding discs when worn or when working with different materials. It also has a soft-start feature to safely start cuts in various materials and for precision cutting. The ergonomic, two-position side grip helps reduce fatigue while also providing a safer hold on the angle grinder. Each power tool is also covered by a five-year warranty covering manufacturer defects, defective units, and normal wear-and-tear. Looking for the next best product?
