There are masonry drill bits that have twists that
help in drilling into steel and other hard metal.
Masonry drill bits are usually used in hammer drills as they are used to drill
hard materials. The bit hammers the materials and then rotates into the work
piece. While hammering, the masonry is broken at the drill bit tip. Then the
flutes of the masonry drill bits carry away the dust drilling into the work
piece. The rotating bit hammers their way to the masonry giving it a smooth
edged hole.
The most common masonry drill bits are with SDS shanks which have spring-loaded
chuck for which helps the bit to chuck with a quick and simple hand-action. This
is quite essential for drilling into masonry. Some masonry drill bits are made
of highly durable silicon bronze alloy as the cutting point. This is something
that you need to look for if you want to do some heavy-duty drilling.
These tips are called durium tip which are available at any hardware store.
These masonry drill bits are typically used by contractors, construction workers
and in other commercial purposes. These bits are usually used in power drills as
those are the type of drills which are used to do heavy woodworking or metal
drilling. But masonry drill bits can also be hammer action power drills for
specific jobs. But in this case you should choose a very high quality drill bit
as the hammering action can result into shattering the bits if it’s made of
cheap quality material.
When you are drilling into harder materials it’s best to opt for low rotation
speed while drilling as high speed drilling could result in overheating the
masonry drill bits which can break the tip. Also it’s important to keep pulling
out the bit to brush off dust so that you can continue with a smooth drilling
action.
Masonry drill bits come in various different sizes smaller bits measure 5mm in
diameter while bigger ones can measure up to 40mm. but these are for reasonably
heavy materials. But if you want to drill through masonry walls then bits
measuring from 300 to 400mm are used to drill efficiently. These are long
masonry drill bits which need to be handled with care. It’s typically used by
construction workers. They are expertise in using such drills and bits.
Tungsten carbide tip are also quite popular with masonry drill bits. These are
bound to spiraled steel shafts. But the durium tip masonry drill bits are much
more durable. These tips can be sharpened by using a drill sharpener or
grindstone. This needs to be done occasionally to give the maximum effect of
drilling with masonry drill bits.
Having a masonry drill bit in your tool box can be helpful at times when you
want to drill through concrete blocks and bricks around your house.
