what is the difference between a hammer drill and an sds drill?

Answer 1

Reading between the lines Skipper, I wonder if you are actually asking.......what is the difference between a common household everyday PERCUSSION drill (often called a "hammer" drill, and an sds drill. If that is your question, a percussion drill usually runs at about 3000 rpm and delivers about 40,000 blows a minute to the drill bit fixed in the chuck. An sds drill runs much slower but has a pneumatic action to deliver the blows, at the rate of maybe 5,000 blows a minute. The pneumatic mechanism gives much more powerful blows and goes through hard material like a knife through butter. Percussion drills struggle in comparison.

Answer 3

yeah it all depends what your calling a hammer drill
you have a roto hammer drill which is the large ones that take splined bits with about 1" thick shafts and can do 3" holes all day long and can also be used as a mini jack hammer. $500.00

A typical drill at the store called a hammer drill / drill combo can do smaller holes with no problem and also be used as a corded drill $80.00 norm.

SDS is a nice hammer drill smaller lighter and more of a type used in small home projects. they also take splined bits but the shafts are smaller than a roto hammer drill. 200.00

all day long and large holes- get the roto hammer

small with little use around the home get drill/hammer combo

small business using often for <5/8 all day SDS

What Is An Sds Drill

Answer 5

Hammer drills & impact drills are essentially the same thing. I would recommend buying him a battery powered hammer drill, about 18-24V. These are much more versatile and also safer as you don't need a 240v supply. They also double up as screwdrivers. Make sure you buy a quality brand, eg De Walt, Makita etc. You certainly won't regret it. Make sure you get a set of masonry drill bits (sometimes a set of drill bits is included with the drill). Get him a pair of safety goggles as well.

Answer 6

Hammer Drill - Has a 1/2'' chuck and key you can use regular bits and masonry bits good to go through stucco....
SDS Roto Hammer can only use SDS Bits with a medium hit and drills in concrete vary well.......
Spline drive Roto Hammer- The biggest of the roto hammer. Has splines on the bottom of the bits with a hard hit, also has attachments to chip away concrete but not as good as a jack hammer....

Answer 7

i agree with most of the info that you recieved, i'd just add that the sds drill picks up where the hammer drill leaves off. the hammer drill is fine for most of your drilling needs up to about a half inch. if you need to go larger or have a lot of holes to drill, then go for the sds.( by the way, sds stands for splined drive shaft )

Answer 8

A Hammer drill, also known as a "rotary hammer" or "roto-hammer", (see also rotary hammer drill) is a rotary drill with a hammering action. The hammering action provides a short, rapid hammer thrust to pulverize relatively brittle material and provide quicker drilling with less effort. Lower power units are usually titled as "hammer drills". Higher power units, usually labeled "rotary hammers", tend to be larger and provide bigger impact forces. Modern units allow the hammer and rotation functions to be used separately or in combination, i.e., hammer mode, drill mode, or both. When used in the hammer mode, the tool provides a drilling function similar to a jackhammer.

A hammer drill is well suited for drilling holes in masonry or stone. It is also used to drill holes in concrete footings to pin concrete wall forms and to drill holes in concrete floors to pin wall framing.

A hammer drill can either be a drill (such as the one illustrated here), or it can be a replacement chuck that is installed on a power drill. When the drill is set to the "hammer drill" position it allows the chuck to move backward and forward over a short distance, allowing a spring to be compressed. When the spring is compressed, the chuck assembly is pushed as far back as it can go against a small eccentric flange. Any rotation of the chuck causes this flange to push back and reverse the direction of travel. The combined action of the spring, eccentric flange and rotation, push the chuck back away from the body of the drill at regular intervals. Under normal operation this sequence causes the whole assembly to "kick" with each turn, jack-hammering the drill bit into the material as it rotates. This helps to break up the masonry so that it can be removed by the drill bit's flutes.

Answer 9

the only difference is the way the drill bit is attached to the drill ..most hammer drills have a chuck which you tighten with a chuck key ..but an sds drill has recesses,...ans so does the drill ..so to fit a bit you pull back the chuck and slip the drill in ..release the chuck and the drill just locks in position ..to remove just pull down the chuck and remove the drill bit

Answer 10

a hammer drill belongs in the 80's . Sds all the way now a days. it takes the work out of drilling and can be found fairly well priced.
