What to consider before buying a drill bit for metal?

It would be incomplete if we do not provide you a final guideline for the best drill bits for metal.

This is why we want to share our all research material with you too.

These are the things which we have looked up to for listing the 7 best drill bits for metal.

We have researched as if we are a buyer for the product and this guideline will hopefully become handy for you too. 

The first thing before buying a bit you have to consider is the coating and the finishing of it. 

Bright finish:

This is the most basic drill finish.

Not only that they are also the cheapest ones.

You can use them to drill on aluminum or low-carbon steel surfaces. 

Black oxide coating:

Black oxide coating on drill bits makes the bits resistant to oxidation.

They add extra lubrication to the drill bits too.

They make the bits resistant to heat and as a result, you get better durability. 

Titanium nitride coating:

This type of coating makes the drill bits ideal for mild steel.

The bits with titanium nitride coating are called with the bits with a gold finish.

Though they do not do well with hard metals, they are good for many applications. 

Titanium carbonitride:

This coating is durable than the titanium nitride coatings.

These bits are good for cast iron or other hard metals.

This coating leaves a bluish or purplish tinge on the bits. 

This is all about the coating and finishing part. After that, we have to consider the facts below,

Frequency of use:

Another factor before buying drill bits to be considered is how often you are going to use your drill bits.

If you need to drill a few holes once or twice in a year there is no need of buying a comprehensive set of bits.

For DIY drillers a small kit with high-quality bits can be a better option.

If you are a DIY worker, then a set of step bits can be a good choice for you.

You can sharpen them or replace them if they get dull later. 

Shank design:

There are dozens of shanks and chucks on the market.

The vast majority of them can be divided into two categories. 

Straight shanks have cylinders that easily fit into Jacob chucks. They are tightened with a key but most require nothing more than your hands. 

Impact guns and drill presses have chucks that can be tightened with chuck keys too. 

There are hex-shanks which are designed to quick change hex chucks.

Choosing the wrong bit that does not have the right shank to match your drill will damage them and your work too.

This might even lead to injuries. 

Price:

It is tempting to purchase cheap drill bits. They are often proven to be of low quality. 

As a result, they become dull after a few uses. 

If you are not sure how frequently you are going to use your drill bits, then you should invest in a set of general-purpose bits.

This will be a clever investment if you need to drill a hole once or twice a year. 

Tip Angle:

Drill bits generally have two types of tip angles.

The aggressiveness of cutting by the bits depends mostly on them.

The difference is found depending on the hardness of the materials. 

For softer materials like wood, plastic you should buy a bit with 118-degree points.

On the other hand for metals, it would be good if you choose the ones with a 135-degree angle. It prevents the drill bit from walking and provides a good grip. 

This is where we stopped.

There are really more things to consider, but those are not worth it. These are the main facts that you must consider before buying a drill bit for metal. 


Drilling through metal: Problem and Solutions

As we are done with the buying I want to point out some things which you might face during the drilling procedure.

They are really basic things.

You can skip them if you are a professional because this is for the beginners. 

  1. The first and foremost thing you need to drill is patience and a steady hand. 

  1. The most crucial thing of drilling and with which people struggle the most is the starting of making a hole. What you should do is that with a center punch you can make a dimple on the surface and start drilling so that the drill does not move around. 

  1. While drilling the bit should be kept at a low speed until it digs into the metal. 

  1. If the bit turns hot and smoke comes out, pause for a few moments and let the bit cool a bit. Then you can start drilling again. 


Conclusion

Well, guys, We are at the end of it. 

I have tried to share with you everything about drill bits so that you can choose the best drill bits for metal for you.

The types of drill bits, the materials they are built with, the things to consider the problems and solutions a list of 7 drill bits for metals.
