The Bosch 11264EVS 1-5/8 SDS-Max Combination Hammer is specifically designed to be used for longer spans of time. This hammer drill is efficient with variable speed, reduced vibration, and a special grip area that makes easy to use. It’s not called a max combination hammer for nothing, seeing as it has more than one mode, including hammer mode and at least 12 different chisel positions. In addition, you can rely on this hammer drill to let you know when the need arises for preventative maintenance through the use of an indicative service light. It truly casts a wide shadow when it comes to hammer drills with amazing features. Though this product is a bit on the pricey side, it is worth all the hassle with specs that are almost unmatchable compared to its counterparts.
