Can you use a rotary hammer drill bit in a hammer drill?
If it fits in the chuck straight, yes you can use it. It will be much more effective in a rotary hammer drill though.
What are some models of corded drill?

What is the best type of drill for hard concrete?
The best drill for hard concrete is one with a rotary hammer action such as a Hilti or Bosch.
What is the difference between rotary drill and hammer drill?
The hammer drill vibrates in and out very fast to make masonry drilling much easier. Rotary hammers are drills with a piston on the inside which is operated by the motor and gears. When the motor turns, it moves a gear, which then moves a rod. The rod hits a hammer mechanism which transfers the strike force into the rotary hammer bit. All of this happens very rapidly. Because there is a piston being struck, the force of the blow against the bit is much harder than that of a hammer drill. Hammer drills have a motor that turns a splined gear type mechanism inside the tool. These splined gears are meshed together and hit against each other creating a vibrating action that is transferred to the drill chuck and bit. The hammering is rapid, but the force is only a fraction of that delivered by a rotary hammer. The primary use for the rotary hammer is to drill holes (from 1/4" to 2" in diameter) in hard concrete using a solid bit. It's also used for light chipping. The primary use for the hammer drill is to drill holes (from 3/16" to 7/8" in diameter) in masonry or brick. It's also used as a heavy-duty drill motor for standard drilling. Typically, a hammer drill has a chuck and uses bits that have straight shanks. Most rotary hammers use bits that have either slots and grooves in the shank (SDS) or spline shanks. Also becoming popular is a slotted shank bit called the "SDS-Max" which is for larger hammers. There is a major difference between a standard hammer drill and a rotary hammer drill. A standard hammer-drill uses 2 grooved plates that rotate opposite of each other; when they slip and the grooves connect, a bang is heard, "hammering" the chuck in and out, allowing a carbide bit to go through masonry materials. This method generates quite a bit of noise and often requires hearing protection. A rotary hammer is extremely more efficient than a regular hammer drill, because it drives a piston that compresses an air pocket, that, in turn, pounds the chuck with measurable impact energy. There really is no question which is better and faster. Rotary hammer drills do the same job in far less time, with less noise and with less effort. For many applications, like drilling into tough materials like aged concrete, a rotary hammer is the only tool to use.
Where can one purchase a rotary hammer drill?
A rotary hammer drill allows for faster drilling with less effort. They are made by a number of manufacturers such as Bosch, Rockwell, DeWalt and Old Milwaukee and are available at building supply stores such as Home Depot, larger hardware stores, tool stores and Sears.
How do you punch a hole in a coin?
You could use a hardened steel punch and a hammer; or a drill, or a rotary diamond tool like a Foredom Tool.
How is hammer drill different from a regular drill?
A regular drill just has a transmission to allow drilling in forward or reverse gear. A hammer drill has a rotary piston or a special clutch, both of which do basically the same job of moving the drill shaft in and out while spinning. Almost every drill make has it's own proprietary method of doing this. This action is necessary for drilling masonry and concrete.
What brand of rotary hammer is highly rated?
The top rated (power) rotary hammer (according to Amazon) is the Bosch 11255VSR BULLDOG Xtreme 1 inch SDS-plus D-handle Rotary Hammer. This has a five star rating.
What is the difference between a hammer drill and a percussion drill?
"Hammer drill" and "percussion drill" are different names for the same tool. In addition to the rotary drilling motion, they use a pair of cam plates to create high frequency in and out motion of the chuck. This helps when drilling brittle materials like masonry, stone, etc. Rotary hammers do a similar motion, but instead of cam plates, they use a pneumatic hammer mechanism which is much lower in frequency but with much more power and stroke. Impact drills are quite different: They have a mechanism which takes effect at high torque loads which makes the rotation "stutter". There is no in and out motion of the chuck. The effect is somewhat similar to an impact wrench.
When drilling Cotswold stone walls what drill and bit do you need?
That's hard stone, don't even bother with a regular drill ! -You need a Hilti or a large Bosch rotary hammer drill with masonry bit that fits it. You can rent these at many stores if you don't think it's worth buying.
What type of drills are used for drilling holes in a concrete block walls?
You would use a hand-held tool called a star drill, and hit it with a three pound hand-held sledge called a "Baby Jack". Each blow of the sledge you turn the star drill 1/4 turn.
Where can one buy a Dewalt hammer drill?
