An authorised Bosch dealer comparison: power, portability, battery life and cost — matched to workshop and site conditions across Assam and the Northeast.
One of the most common questions at our Guwahati counter: should I buy a cordless drill or a corded one? The answer depends on your application, your site conditions, and your budget. This comparison is written for electricians, fabricators, maintenance technicians and contractors across Northeast India.
| Power Output | Corded: consistent full power at all times. Cordless: slightly lower torque on older brush motors; modern 18V brushless models match corded for most tasks. |
|---|---|
| Runtime | Corded: unlimited — runs as long as power is available. Cordless: battery-limited; 60–240 min per charge depending on capacity (2.0–4.0 Ah). |
| Portability | Corded: tethered to a power point or extension cable. Cordless: fully portable — ideal for scaffolding, rooftops and remote sites in Arunachal, Nagaland and Mizoram. |
| Weight | Corded: typically lighter (1.5–2.2 kg). Cordless: heavier with battery (2.0–3.5 kg for 18V), though balance is better in some models. |
| Cost | Corded: lower upfront cost (entry models from ₹2000–4000). Cordless: higher initial investment due to battery and charger; long-term cost balances out. |
| Maintenance | Corded: brushes wear; easy to replace. Cordless: battery capacity degrades over 500–1000 charge cycles; replacement batteries available. |
| Best Use | Corded: workshop, bench drilling, heavy production use. Cordless: site work, elevated positions, confined spaces, NE remote sites without power. |
The Bosch GSB 600 RE is the most popular corded impact drill at our counter — 600 W, 13 mm chuck, reversible, hammer function, suitable for wood, metal and light masonry. For heavier work, the GSB 13 RE and GSB 16 RE Professional handle larger diameter drilling in concrete block.
Corded drills are the right choice if you have a permanent workshop or consistent power supply — and they're the lower-cost entry point for apprentice mechanics and fabricators starting out.
The Bosch GSR 18V-Li (GSR 183-Li) is our most-asked-for cordless model — 18V Li-Ion, brushless option available, two-speed gearbox, suitable for furniture assembly, electrical work and general maintenance drilling. Battery is compatible across the entire Bosch 18V platform (drills, angle grinders, jigsaws).
For contractors who move between sites across Assam, Meghalaya or the hill states, the cordless range removes dependency on extension cables and generator connections entirely.

For light masonry — drilling through brick or single-layer block walls for anchors and conduit — an 18V brushless cordless drill with hammer function handles the job well. For continuous heavy masonry, concrete drilling or rock in construction sites across Arunachal Pradesh, a corded SDS rotary hammer (Bosch GBH range) is the better tool. We can help you pick the right model — call +91 91812 13332.
A Bosch GSR 18V Li-Ion with a 2.0 Ah battery typically gives 60–90 minutes of active drilling, or 180–240 minutes with a 4.0 Ah battery. For a full day on site, carrying two batteries and keeping one on charge is the standard practice. We stock Bosch 18V batteries and fast chargers at our Guwahati counter.
