Incorrect use of a metal hole saw is asking for trouble

While it is a noble enterprise to

attempt to perform your own DIY

repairs in the home, it should be

remembered that larger tasks must not

be attempted and should instead be left

to professionals. This is because a

simple mistake could lead to a lot of

damage.

Using tools which are unfamiliar to

you such as an annular cutter could be

downright dangerous if you have not

taken the time to do some research and

find out the correct method of using it. A

poor DIY job could end up costing you

more in the long run as a professional is

eventually needed and must clean up

your mess before they proceed. This is

not to say that DIY jobs should not be

undertaken. If done correctly, they will

be as rewarding as anything you have

ever done.

Perhaps you are looking to install

something in the home but you need to

create a hole in the middle of a solid

surface. Those unused to DIY tasks may

consider this to be an impossible task

when it is in fact anything but.

A metal hole saw can be used for

this job but they should be used with

caution. It is possible to cut a perfect

hole in just about any surface thanks to

the range of saws available. For

example, if you believe that cutting a

hole in a concrete surface cannot be

done, think again. There is a concrete

hole saw specifically for this job.

In general, you are looking at two

distinct types of metal hole saw that are

regularly used. Blade tipped saws are

the most popular and glide through

metal and wooden surfaces like a knife



through butter. There are also saws that

come with diamond tipped edges and

these cut through solid surfaces at a

slightly faster rate than their blade

tipped counterparts. However, the

difference in price between them is so

vast that it is really not worth paying the

extra amount unless you are a

professional.

Although the metal hole saw may

seem like some exotic tool, it actually

does not vary from the a regular drill in

the way it works. The circular cap is just



a drill bit of a different shape which is

kept in place by a pilot bit. An arbor is

then used to attach the circular blade to

the drill. This ensures that the cutter

does not slide out of place and is safe to

use when cutting through surfaces.

Inexperienced DIY enthusiasts may

accidentally use the saw without either

the arbor or pilot bit which is

inadvisable. Using the saw without these

safety elements is likely to lead to

serious injury.


A metal hole saw is the ideal tool

for drilling into doorknobs to install

locks and is capable of cutting through

even the most durable metal. This type

of saw is an instrument that can be used

creatively in the right hands but could

cause damage to property and the person

holding it if used incorrectly.


Don't cut corners when using a metal hole saw

There are occasions such as trying

to bore a hole in a solid object which

causes people to ask for the assistance of

an expert. To them, it seems like such a

task is far beyond their capabilities.

What they don’t realize is that

equipment like a metal hole saw can be

used by just about anyone as long as

they carefully follow the instructions.

All of a sudden, seemingly impossible

tasks like cutting a hole in a doorknob to

install a lock are very achievable. These

saws are circular and allow even a DIY



beginner to easily saw through solid

metal. If it is another material like

tubing that needs to be cut through, an

annular cutter can do the job without

causing the object to crack or dimple.

A metal hole saw is a metal

cylinder that is mounted onto an arbor. It

is possible to find saws that have

industrial diamonds instead of teeth but

usually, the cutting edge consists of

metal teeth which should make short

work of softer metals like brass or

bronze. Once you have cut through the




first part of the metal, the centering

mechanism ceases to be in use though it

still prevents the saw from going too

deep. Hole saws usually have a

maximum diameter of five inches with

cylinder lengths of up to 12 inches not

uncommon.

Saws with metal teeth are usually

used for the majority of metals as well

as wood and plaster while saws with

diamond teeth can be used to deal with

concrete and glass.


A metal hole saw is far more

efficient than regular drill bits because it

only has to cut a small amount of

material to create a large hole. This

means it requires less power and uses up

less electricity. It is also capable of

boring holes which are much wider than

what can be achieved by a drill bit.

However, in order to be effective, the

saw must be able to produce a huge

amount of torque at a relatively low

speed. It is easy to allow the saw to bind

because of excess dust and long



side-handles must always be used as an

extreme kickback occasionally occurs

during use.

An annular cutter is preferable to

a twist drill when creating holes in pipes

and tubing because it is hollow and

therefore, has no ‘dead-zone’ resistance

which can cause twist drills to slow

down when in motion. Annular cutters

maintain their speed throughout which

ensures that a clean and crisp hole is

produced without dimples and burrs.

When using this type of cutter, it is




important to maintain a constant feed

pressure. Allowing the feed rate to

remain slow could cause the cutter to

stall or even break.

When you use a tool like a hole saw

or annular cutter to create holes, you

have a machine with awesome power in

your hands. These machines enable you

to make large holes without damaging

any of the material surrounding the hole.

Simply follow proper safety procedure

and you will no longer need to call a

professional every time you need a hole

drilled..
