The Bosch GBH 7‑46 DE is a high-performance SDS‑Max rotary hammer, engineered for heavy-duty drilling and chiselling into concrete, brick, and stone. Powered by a robust 1 350 W motor, it delivers up to 15 J of impact energy in Turbo‑Power mode for maximum material removal. With its durable metal construction and Turbo‑Power feature, it achieves high productivity and long service life.

Featuring a nominal speed of 145–280 rpm and an impact rate of 1 375–2 800 bpm, the GBH 7‑46 DE can drill up to 45 mm in concrete, 80 mm with breakout bits, and 150 mm using core bits. Its compact dimensions (288 mm wide × 545 mm long × 105 mm high) and an 8.2 kg weight make it manageable yet powerful.

The tool includes vibration-controlled auxiliary handle, speed preselection dial, and a lockable switch for chiselling applications. A central lubrication system and replaceable SDS‑Max holder ensure durability under tough conditions.
