Key Takeaways
- Bosch adds two professional‑grade metal‑working tools: the GBM 38 magnetic core drill (10.5 kg) and the GRS 18V‑330 right‑angle impact wrench (330 Nm torque).
- Both tools focus on lightweight construction, thermal protection, and ergonomic design to cut operator fatigue.
- The GBM 38 is 40 % lighter than typical core drills, while the GRS 18V‑330’s compact head (78 × 56 mm) reaches into the tightest engine‑bay spaces.
- Brushless motor technology delivers higher efficiency and longer service life for the cordless wrench.
- Bosch supplies a complete accessory kit for the drill and a high‑capacity battery for the impact wrench, enabling immediate field deployment.
Bosch Expands Its Professional Metal‑Working Line
Bosch Power Tools has introduced two new additions to its industrial portfolio, aimed at fabricators, maintenance crews, and automotive technicians who need high power, precision, and comfort in demanding environments.
GBM 38 Professional Magnetic Core Drill
- Weight: 10.5 kg (≈ 23 lb) – roughly 40 % lighter than conventional 38 mm core drills.
- Drilling Capacity: 38 mm core diameter in steel up to 25 mm thickness.
- Power Supply: 230 V AC, 2.5 kW motor.
- Safety Features: Integrated thermal overload sensor and a replaceable current‑fuse that protect the motor during prolonged use.
- Ergonomics: Balanced handle and low‑center‑of‑gravity design reduce shoulder strain, especially during overhead work.
- Included Accessories: Magnetic base, drill steel, three core bits (20 mm, 30 mm, 38 mm), and a quick‑release chuck.
The GBM 38’s reduced mass and robust magnetic clamping make it ideal for high‑elevation installations such as structural steelwork, HVAC ducting, and concrete reinforcement.
GRS 18V‑330 Professional Right‑Angle Impact Wrench
- Power Source: 18 V lithium‑ion battery (Bosch 5.0 Ah pack).
- Torque Output: 330 Nm fastening torque, 560 Nm break‑away torque – sufficient for bolts up to M18 (≈ 18 mm).
- Motor Type: Brushless, delivering 30 % higher efficiency and a 2‑year warranty on the motor.
- Dimensions: Head 78 mm × 56 mm, overall length 210 mm; fits into engine bays, pipe flanges, and confined structural joints.
- Speed Settings: 2‑speed gearbox (0–2,800 rpm low, 0–3,600 rpm high).
- Additional Features: LED work light (150 lumens), vibration‑dampening grip, and an electronic overload protection system.
The compact geometry and high torque make the GRS 18V‑330 a go‑to tool for automotive service centers, plant maintenance, and on‑site construction where space is at a premium.

Why These Tools Matter to Professionals
- Reduced Operator Fatigue: The GBM 38’s 40 % weight reduction and balanced grip lower shoulder strain, while the GRS 18V‑330’s vibration‑dampening handle minimizes hand fatigue during repetitive bolt‑tightening.
- Increased Uptime: Brushless motor technology in the impact wrench extends run‑time between charges by up to 25 % compared with brushed equivalents.
- Safety & Reliability: Built‑in thermal protection for the drill and electronic overload for the wrench help prevent premature motor failure, a critical factor for contractors on tight schedules.
- Rapid Deployment: Both products ship with complete accessory kits, allowing technicians to start work on the first day without additional purchases.
