A reamer is a drill bit that is used to shape or
enlarge holes. Now, there are many different kinds
of reamers. There are the adjustable hand reamers,
the straight reamer, the machine reamer, the rose
reamer, the shell reamer, the tapered reamer, the
Morris taper reamer and the combination reamer.
The most popular reamers are the hand reamer and
the tapered reamer. Choosing the correct reamer
can make any job a success or a complete failure.
Also, it can take a lot more time to complete a
project if you do not have the proper tools and in
today’s economy time is money.
So how do you know which reamer is best for
your project? First of all you need to make sure you
have the proper equipment at your disposal to
operate a reamer. A reamer will be extremely
successful when using either a lathe or a drilling
machine otherwise known as a drill press.
Secondly, all reaming jobs must be preceded by
drilling a hole to begin with a little smaller than
the size needed. By smaller it is recommended that
the allowance is no more than 0.13 of a millimeter.
The allowance is the difference between the hole
drilled in the first place and the desired diameter of
the hole upon completion of the project. If you
have an allowance greater than 0.13 of a millimeter
it can severely damage the reamer to the point that
it could never be used again.
Okay, now that you have your hole predrilled
in the material you are working with, which type
of reamer should you use? Well, if all you want to
do is clean up the burrs from the hole and make it
look neat and clean, you can use a tapered hand
reamer for this. However, if your hole has to be
precise, you may want to consider using a tapered
machine reamer constructed for precision. These
reamers can get a hole within 0.02 of a millimeter.
Also some jobs require that the cylinder walls of a
hole have a smooth surface finish. This is needed
for many precise engineering applications.
Reamers can be used on a variety of materials
varying from plastics to cast iron to aluminum. If
you are working with metal or plastic, reamers are
the perfect tool for precision. However, if you were
working with concrete or stone a reamer is not a
good choice for materials of this nature. Instead of
ruining a good and expensive reamer, use masonry
drill bits. Usually holes in concrete or stone do not
have to be as precise with an allowance of less than
0.2 of a millimeter. Masonry drill bits will get the
hole close enough for concrete and stone.
As you can see, reamers are a wonderful tool
for projects that require precision. However, as
with anything, they have their limits as to the
material best suited for use. You cannot go wrong
using masonry drill bits when it comes to concrete,
stone or tile.

Whether you want to drill a hole in metal,
wood or stone, it seems that old fashioned drill bits
just don’t cut it any longer. With the advent of
more advanced tools like the annular cutter, the
shelf life of traditional drill bits seems to be
limited. Certainly, when it comes to drilling
normal sized holes in rock or creating large holes in
solid metal, there are far better types of machinery
on the market than what your father has in his tool
box. As modern consumers, we demand more of
the equipment we use for home improvement
projects. Holes no longer crack or have dimples
surrounding the surface area when the new wave
of home improvement tools is put to use.
Drilling a large hole in a door to put in a
doorknob is an age old DIY job. One method of
achieving this hole was to drill several holes beside
each other. Eventually, the holes would combine to
create something resembling a space for a
doorknob to be placed. This process took some
time and required great patience. Of course, the
above scenario really involves amateur DIY
enthusiasts but even they can benefit from the
power and convenience of an annular cutter.
Instead of having to bore primer holes before
getting to work with the big drill bit, this type of
cutter allows you to go straight through the metal.
You will only have to use it once to cut the perfect
hole.
All you need to do is ensure that the surface
being drilled is clean and free of all debris. Most
cutters are magnetic nowadays so the bottom of the
magnet must also be thoroughly cleaned. The
cutting edges of the cutter are located right at the
edge which allows the surface speed of the tool to
remain constant during the cut. Instead of having
to force your way through the material like you
would with a normal drill bit, the cutter smoothly
saws through the metal, never pausing throughout
the job unless you elect to stop and clean the cutter.
Masonry drill bits are the weapon of choice
when it comes to dealing with stone and concrete.
They are a major improvement over older drill bits
which had a pronounced habit of either breaking
under extreme pressure or chipping the rock. These
types of drill bits work best when paired with
rotary hammer drills because they operate a piston
which hammers the drill bit into the hole. In
contrast, regular hammer action drills tend to
vibrate. If the material is extremely hard and
pressure is put on the drill bit, it could crack.
Rotary drills are more expensive but as they
penetrate hard material more easily than their
regular hammer counterpart, it is certainly worth
paying a little extra.
If traditional equipment is not up to the
standards we now have, items like masonry drill
bits are here to save the day. Consumers
understand the importance of longevity and
performance and this realization has encouraged
manufacturers to produce superior quality goods.
