Title: The Circular Saw That Does Not Need Electricity


1
  • The Circular Saw That Does Not Need Electricity

2
  • When somebody mentions a circular saw the first
    thing that comes to our minds is a portable saw
    with a 7 1/4 of an inch blade.
  • The saw requires electricity and in many cases a
    really strong supply of electricity.

3
  • These saws are awesome at the job for which they
    were constructed.
  • A circular power saw is vitally important to the
    construction of a house.

4
  • But there is another tool that is very important
    as well although its not as popular as the
    circular power saw.
  • This tool is the metal hole saw otherwise known
    as hole cutter.
  • This is a circular saw that can cut through a
    variety of materials with little ease.
  • However, this saw cannot be used independently.

5
  • It requires the use of a powerful drill to
    operate.
  • It does not have a power cord but rather is an
    attachment that secures to the drills chuck.
  • Once connected properly, the metal hole saw has
    the potential to cut holes from ½ of an inch up
    to six inches.

6
  • Unlike the step drill bit which has a very
    limited thickness into which it is capable of
    drilling, the metal hole saw can cut holes six
    inches in diameter and up to three inches of
    depth.

7
  • The step drill bit can drill successfully up to
    1/8 of an inch.
  • What a difference to be able to drill three
    inches in depth!

8
  • With wood if your depth is greater than this
    three inches you can still use the metal hole
    saw.
  • What you do is drill down the three inches that
    the metal hole saw allows and then pull the saw
    out of the hole.

9
  • You will notice that there is a hole in the
    middle from the pilot drill bit and a clearly cut
    edge all the way around the hole.
  • Now, take a wood chisel and carefully chisel the
    middle of the block.

10
  • It should, with little effort, break a couple of
    inches out of the wood.
  • If you are careful you can do this without
    damaging the outer intact ring that the hole saw
    cut in the first place.
  • After you have taken part of the wood out, you
    can insert the drill with the metal hole saw back
    into the hole and continue drilling even farther.

11
  • This method allows you to use a metal hole saw to
    cut holes in wood even deeper than the previously
    thought depth.
  • Another really cool thing about the metal hole
    saw is the versatility of this marvel of
    ingenuity.
  • There are metal hole saws that are adjustable to
    different diameters that you need.

12
  • Many people do not like the adjustable hole
    saws because they tend to not be as accurate or
    durable as the fixed model.

13
  • If you are one of these people and want to
    consider the long term, it is recommended that
    you buy fixed model metal hole saws.

14
  • Even with the fixed model, the pilot twist
    drill bit in the middle is usually
    interchangeable.

15
  • So now that you understand the use of this
    circular saw go have some fun making holes.
