Visit one of the several sites that carries full lines of Bosch Tools. Links are provided under "Resources." The first link goes directly to the official Bosch Tool website.
Select the "Power Tool" tab on the left side of the screen. This brings up categories for different kinds of power tools.
Select the category your tool would be listed under. If you are looking for a cordless saw or drill, look in the "cordless" section, not the "saw" or "drill" sections. This brings up another list of categories. These categories vary from robust tools that take up more voltage to accessories, such as additional batteries or drill bits. Consider what job you will perform with the tools before purchasing the product. There is no need to purchase a 36 volt drill when you will use it only to hang picture hangers into drywall. Likewise, you don't want a 4 volt drill to cut into cement.
Make your final selection, then proceed to the checkout. Follow the prompts to complete the purchasing process and submit your order.
