المطرقة الدوارة (مثقب) من بوش موديل (GBH-8-45-D) استطاعة (1500W)

The GBH 8-45 D is a high‑performance SDS Max rotary hammer designed for heavy‑duty drilling, hammering, and chiseling in concrete, masonry, and stone. With a robust 1500 W motor and high impact energy, it delivers fast progress on demanding on‑site tasks, while its ergonomic design and vibration control help reduce fatigue during extended use.

Key specs include a powerful 1500 W motor and an impact energy of 12.5 J, SDS Max chuck for quick bit changes, multi‑function operation (drilling, hammering, chiseling), vibration control for improved comfort, constant electronic speed control for steady performance under load, and Intelligent Electronic Motor Protection (EMP) to guard against overload.

SDS Max is a secure, tool‑less bit change system that allows fast, confident bit changes and better energy transfer to the bit. It reduces downtime, minimizes bit slipping, and enhances overall efficiency on tough demolition and drilling tasks in concrete and masonry.

Mode switching is done via the selector switch on the tool. Choose drill mode for precise holes, hammering mode for impact drilling, or chiseling mode for removing concrete or masonry. The constant electronic speed control helps maintain consistent performance in each mode.

It’s well-suited for heavy‑duty concrete drilling, masonry work, and demolition tasks. You can bore large holes, break out sections of concrete, or remove stubborn material in professional construction or renovation projects.

To install a bit, insert it into the SDS Max chuck until it seats securely, then lock it in place. To remove, pull back the chuck collar and extract the bit. No separate chuck wrench is required, making bit changes quick and simple on the job site.

Wear appropriate PPE (eye protection, hearing protection, gloves, dust mask). Use a compatible dust extraction setup to manage debris, keep a firm stance and use two‑hand grip, and avoid overloading the tool. The vibration control and EMP help enhance safety and tool longevity, but prudent handling and bit selection are essential.

Vibration control reduces user fatigue during long sessions, while Intelligent Electronic Motor Protection (EMP) guards the motor against overload. Constant electronic speed control maintains stable performance even under load, helping you complete tasks with greater precision and reliability.

Yes, its ergonomic, compact design and well‑balanced handle improve control in tight spaces and during overhead tasks. However, always assess workspace clearance and ensure safe operation when working above shoulder height.

Consider its SDS Max capability, 12.5 J impact energy, 1500 W motor, and advanced safety features like vibration control and EMP. If you regularly tackle heavy‑duty concrete tasks, this model typically provides strong performance, durability, and long‑term cost efficiency compared with lower‑specification units.
