Buying advice

When choosing drill bits, consider the materials you drill most often. For metal or stainless steel, opt for cobalt or carbide bits; for general DIY, titanium or black oxide offer good value. Impact drivers require bits with hex shanks. Prioritize sets with a sturdy case to keep bits organized and protected.
