Bench rammers are the smallest type of tamper and range anywhere from 14” length to approximately 30” in total length. They can be used for a multitude of purposes but are mainly used in the refractory industry or foundries for packing substances that are fine in texture such as powders rather than earth. They can be used in tight areas such as drums or barrels and can be mounted to a bench for specific tasks. They can have various size butts placed on the end that range from 2 to 5 inches in diameter and the butts can be made from rubber, aluminum or steel.

Foundry Tampers are generally used in Foundries as well but are a “stand-up” version and are generally 4 feet tall. They look much like a standard Earth Tamper but usually have a rubber butt on the end that is anywhere form 2 to 4 inches in diameter. They are lighter than a standard Earth Tamper because of the material they are used on.

Earth Tampers are a heavier tamper ranging from 35 to 60 lbs and generally have a 6” diameter butt on them that is made from steel or aluminum. They are used for packing earth, creating earth homes, tamping poles and fence work and are also used of developing sand bunkers on golf courses. Tampers are generally 48” tall but can be shortened by threading the handle directly into the body of the tool. Earth tampers generally have a standard ¾” threaded port in them so the pole can be removed and replaced with a shorter one if it is necessary for what you are working on. Some guys will purchase a standard ¾” gas pipe from their local hardware in the length that they want but note that tamper poles are specifically designed with thick walls to handle large air pressure and standard gas pipe does not compare and would be deemed dangerous if used for a long periods of time. They will generally rust over time also making them weak. Typically butts can be changed out and are specific in taper to fit certain models. All butts are not universal and cannot always be switched from one model to another. Some are fastened to the piston rod with screws and some are pressed on.

Note: There are important things to remember when owning a tamper.

1.) Never leave your tamp on the ground or leaning against a wall when the air line is hooked up. Accidents occur when they either fall over on the live handle or accidentally roll ever on to the live handle.

2.) Always unhook the air line or shut-off the air pressure to the tool when taking a lunch break or any break for that matter.

3.) If you have the air line unhooked never the lay the tool down in the dirt. Always lean upright preferably in a corner. Any slight amount of debris or even a tiny stone that gets into the end of your air inlet could possible render the tool inoperable. There are valves that have tiny holes in the tool and when those valves get clogged the tool will stop working. I can not stress this piece of advice enough based on repair experience.

Pavement Breakers / Jack Hammers / Demolition Hammers
When you are determining the right tool for the job you need to ask yourself a few simple questions.
What is the material you are working with? What kind of time frame are you looking to do the job
in? How often do you plan on using the tool? All of these questions are very helpful. This Guide is
not to be considered to be the “bible” and is only meant to be in a generally speaking format. There
are plenty of exceptions to the rule but this guide should help you in determining which kind of tool
you should be using for your specific job.

Generally speaking
All pavement breakers and jack hammers are considered to be a certain weight class tool. The weight class of a hammer is like determining the size of the hammer. As far as hand-held pneumatic hammers go, the weight classes are typically as follows: Jack Hammers: 80-90 lb., 60 lb., and 35-40 lb.

Note: 90, 80, 60, 40, 30 class is only a general tool weight term it does not represent the actual weight of the tool.

80-90 lb. class pavement breakers are generally used on highways and streets, busting
up hotel foundations, commercial building foundations, and industrial complexes where
large construction equipment cannot get into or reach. Concrete or rock is generally 6"
thick or more. This class tool generally takes 1-1/4" hex x 6 or 1-1/8" hex x 6 bits.

60-80 lb. class pavement breakers are generally used for standard residential driveways,
sidewalks, streets, and some highway use but mostly where concrete is somewhat 4-6"
thick. This class tool is also used for breaking up some basements in the Midwest
and they are also good for post driving dock poles and small sea walls in the marine
industry. This class tool generally takes 1-1/8" hex x 6 or 1-1/4" hex x 6 bits

35-40 lb. class pavement breakers are used for small jobs such as removing single 4 x 4 ft. squares and 3 x 3 ft.
squares of sidewalk that are 2-4" thick. They are also used for getting into cornered areas and cleaning up edges of broken concrete where a 60 or 80 lb.class tool has already been. They are also used to get in between rebar and other tight areas. This class tool can also double as pneumatic shovel to dig into hard clay or around small trees there are spade bits that can be purchased for these tools to do the job. This class tool generally takes two size bits,
7/8" hex x 3-1/4" or 1" hex x 4-1/4" bits. (some tools will take 7/8" hex x 4-1/4" bits but seem to be rare)

Bit Sizes for Pavement Breakers
While there are many different sizes and shapes to bits the ones mentioned above are the most
common. The measurement of bits are generally taken this way for example; a standard 1-1/4" hex x 6
bit means that the hexagonal end of the bit is 1-1/4" from one side of the fl at to the opposite
side of the flat. The “6” stands for the 6" of length from the collar on the bit to the short end of the
bit in inches.

Myth: {1-1/4" hex bits hit better than 1-1/8" hex bits or 1" hex bits hit better than 7/8" hex bits.}

The tool controls the hit. The larger bit may just last a little longer down the
road. Most tools can be set up or “bushed” to accept either size if you already own a
specific size bit and would like to keep all of your tools using the same size bits.
