Corded hammer drills are a simple and practical tool. First and foremost, you should consider its consistent power: whatever your project may be, this stability of electricity supply will help to guarantee that the job gets done without any interference from battery problems. Secondly, it is generally very powerful indeed when compared with its cordless cousin - not only saving weight but also generating enough might to cope with tough materials in turn. Thirdly, in the absence of a battery, this tool is lighter and easier to handle. Also, non-battery l you don't have to worry about finding the right charger for it: simply plug your corded hammer drill in and off you go. In addition, its cable may be your excuse for throwing an existing model out - but with no maintenance to speak of, corded drills (which are typically priced between CNY 40 and CNY 60) have time on their side and need only be used as needed for several years before they will require less part replacing than cordless models. All these advantages make the corded hammer drill an excellent choice for professional trades people who need high performance tools at affordable prices, as well as home repair workers or remodelers with their own projects and budgets to look after too.
