Design and Usability
The Milwaukee 2888-20 is designed with user-friendliness in mind, featuring a paddle switch and tool-free guard adjustment for easy operation. This design enhances the overall user experience, especially for those who prioritize efficiency. The Proxxon 38544, being a mini angle grinder, is compact and lightweight, making it ideal for use in tight spaces. Both tools are equipped with features that enhance usability, but the Milwaukee's larger size may be a consideration for users looking for portability.
Included Accessories
When it comes to included accessories, the Proxxon 38544 stands out as it comes with a carborundum grinding disc of 60 grit and a reinforced fan sander. This inclusion adds value for users who need immediate functionality right out of the box. The Milwaukee 2888-20, however, is sold as a tool-only option, meaning users will need to purchase accessories separately. This could lead to additional costs for Milwaukee users, which is an important factor to consider when evaluating overall value.
