The Bosch GBH18V - 45CK27 18V PROFACTOR cordless rotary hammer is a game - changer for heavy - duty concrete drilling and chiseling. This 1 - 7/8 SDS - max rotary hammer offers corded - like performance, perfect for tough jobs. It delivers an amazing 9.3 Ft. - Lbs. of impact energy (EPTA), which is unbeatable for a single - battery 18V SDS - max 1 - 7/8 In. rotary hammer.

As part of the PROFACTOR System, it pairs BITURBO Brushless Technology with a CORE18V PROFACTOR battery. The BITURBO system features a high - performance brushless motor and drive - train, delivering power comparable to high - demand corded tools. The anti - vibration system, with a longer air cushion in the hammer tube, dampeners in the handle, and a counter - balance weight in the mechanism, reduces user fatigue.

Using the Bosch GBH18V - 45CK27 is a breeze. First, make sure the battery is fully charged. Insert the battery into the hammer. If you're going to drill or chisel, select the appropriate mode on the tool. For softer materials like brick or tile, use the Soft Start feature to control the speed. When using the chisel, you can use the Vario - Lock to adjust its angle for better working position. Be careful when using the tool, especially in binding conditions, as the KickBack Control helps but it's still important to hold the tool firmly. Keep the tool clean after each use. Wipe off any dust or debris from the body and the chuck. If the tool gets wet, dry it thoroughly before using it again. For the battery, don't overcharge it. Use the provided turbo charger and follow the charging times. If you're not going to use the tool for a long time, store the battery in a cool, dry place. And remember, this tool comes with a 180 - day no - question - asked return guarantee, so you can use it with confidence.
