Top 4 Best Drill Bits For Metal Black Friday Deals 2018

Best Drill Bits 2018

What makes the very best and top-rated drill bits? Then you understand how hard that maybe if you have tried drilling through hardened steel, or metal.

Using a normal drill bit designed for metal materials that are normal won’t work, and in fact, will destroy that bit for some other uses.

The ideal grill for taking on hardened steel is really a”Cobalt HSS” drill bit which has been specifically designed for this purpose.

Recognizing Hardened Steel

I find that if I understand how something is created, that it is easier to understand how you can work with it.

Steel put it through the processes of tempering and quenching and will take an ordinary steel that is high in carbon content.

To harden steel high temperatures are used, and that type of steel must have a great deal of carbon in it, to begin with.

All hardened steels go. It is important to say that the carbon steel is heated to elevated temperatures that harden the steel.

It is then dipped into water, pretty much in the way you would observe a working, but making it brittle.

The tempering process reduces how brittle the steel becomes and the net result is you’re left with a steel product that is tough.

I’ve included a video below on how to assess whether it really made from steel.

Uses of Hardened Steel

Hardened steel can be used for objects which are subject to high levels of abuse or force such as car parts cranes, trucks, hand gear, guns, and knives to mention but a few. When compared with normal steel, hardened steel is more durable, more resistant to wear and tear and perfect substance for all sorts of heavy duty applications.
