Yes, hammer drills can handle concrete for small holes and occasional use. However, for frequent concrete work or holes larger than 10-12mm, a rotary hammer (SDS-Plus) is much more effective and less fatiguing. Use quality carbide-tipped masonry bits and always wear safety glasses and a dust mask.

Brushless motors are more efficient, provide longer runtime, generate less heat, and last longer. They're worth the extra cost if you use the drill frequently. For occasional DIY use, brushed motors are still perfectly adequate and more budget-friendly.

Ideally 2+ batteries for cordless drills. This allows continuous work while one battery charges. For professional use or long projects, consider 3 batteries. Higher capacity (4.0Ah+) batteries provide longer runtime but cost more. Start with the kit and add batteries as needed.

12V drills are compact and lightweight, good for light tasks. 18V/20V is the sweet spot for most users - enough power for all common tasks without being too heavy. Note: 18V and 20V are the same (18V nominal, 20V maximum) - just different marketing by manufacturers.

Choose cordless for portability and convenience, especially for general home use. Modern cordless drills are powerful enough for most tasks. Choose corded for heavy-duty use, workshop situations, or if you're on a tight budget. Corded drills provide consistent power and cost less upfront.

Bosch has the strongest pan-India service network, followed by Makita and DeWalt in major cities. Stanley and Black+Decker also have decent coverage. Always check if your chosen brand has a service center in your city before purchasing. Avoid grey market imports as they typically have no local support.

Start with a basic set including: HSS bits for metal (1-10mm), masonry bits for concrete/brick (6-12mm), wood bits (6-20mm), and screwdriver bits (Phillips, flathead, Torx). Invest in quality bits from reputable brands - cheap bits dull quickly and can damage your drill chuck.
