Quick Answer: For serious concrete and masonry work, the Bosch GBH2-28L rotary hammer is our top pick. Its 2-pound rated impact energy plows through rebar-reinforced concrete while staying manageable for overhead work. If you only drill occasional anchor holes, a hammer drill will suffice, but for regular masonry work a rotary hammer is essential.
What to Look For
The most important spec for concrete drilling is impact energy, measured in foot-pounds. Rotary hammers use an electro-pneumatic mechanism that delivers far more force than standard hammer drills, which simply vibrate the bit rapidly. Look for SDS-Plus chuck systems for bits up to 1-1/8 inch, and SDS-Max for larger holes. Anti-vibration technology matters significantly since sustained concrete drilling causes fatigue and long-term joint issues. Variable speed control lets you start holes cleanly without wandering. Dust collection compatibility is increasingly important on jobsites due to OSHA silica dust regulations. Weight is a practical concern for overhead drilling into concrete ceilings or lintels.

How to Choose
If you drill into concrete weekly or more, invest in a rotary hammer. The Bosch GBH2-28L is unmatched for corded reliability on heavy commercial jobs. For contractors who need cordless flexibility, the Milwaukee 2912-20 pairs perfectly with an existing M18 battery fleet. The DeWalt DCH273B is the best choice for weight-conscious users doing overhead anchoring or those already on the 20V MAX platform. For homeowners who only need occasional concrete anchors, a quality hammer drill mode on a standard drill will handle light-duty work without the extra investment.
FAQ
What’s the difference between a hammer drill and a rotary hammer?
A hammer drill vibrates the bit rapidly while spinning. A rotary hammer uses an internal piston to deliver actual hammer blows, producing 3-5x more impact energy. For anything beyond small anchors in block, a rotary hammer is vastly more effective and less fatiguing.
Can I use a rotary hammer for regular drilling?
Yes, most rotary hammers have a rotation-only mode that works for standard drilling. However, the SDS-Plus chuck requires SDS bits, so you will need adapters or dedicated bits.
Do I need a dust collector for concrete drilling?
OSHA silica dust regulations require dust control on construction sites. Even for home use, a vacuum attachment dramatically reduces cleanup and protects your lungs. Most rotary hammers now have integrated dust collection ports.
