Benefits of Step Drill Bit

Owing to their pine tree-like shape, you can start small and go bigger with step drills. A fancy luxury you aren't likely to find in other bits. But here are some other pros of these conical bodied bits.

Different Sized Holes

An advantage you're only going to get with step bits is you can change the size of the hole without changing the drill bit. Further, you can also make existing holes bigger.

However, if your sheet is bigger, this becomes a double-edged sword as your hole gets bigger, the deeper you dig in, even if you don't need it to.

Clean and Round Cuts

Your cuts will be accurate and rounded. They won't be rough or have rugged corners. But more importantly, it will be clean and won't leave much after itself to clean.

No need for Twists and These are Self Starting

Pilot holes are small drillings needed to fit in the edge of the drill bits. But owing to its conical shape, step bits already have the sharp head to edge in without needing you to put additional pressure and twists.

Won't deflate or Damage the Sheets

When you're going for precision cuts, you will want these drills because their straight flutes softly plunge in without damaging the shape.

Neiko has already impressed us with their products, but what makes this still the spotlight is the value you get from this tool. If you want to cut through metal with absolute control, you won't find a better drill bit than this. It cuts fast, and it pierces with accuracy.

If you hate to clean the mess after a job, then you will prefer this all the more as this was designed in a way that spreads very little dust and debris.

Knoweasy brings one of the most affordable drill bits. We weren't expecting anything extraordinary from this, and you shouldn't either.

This is priced reasonably amongst the pricier step bits. But they haven't sacrificed much in the way of functionality, and that's the reason for including this.

It can't be sharpened and won't last forever, but if you want a step bit for a specific task, you don't have to spend more than you want to for it. That's where this tool awes all.

With its hexagonal shank, you can easily drill into sheets. You will have to follow the proper steps when using it on tougher sheets, but for soft metals, plastic and copper, these are more than enough.

Further, we like the mechanism of its flute design; the double-edged pattern makes the tip sharp and easy to reap into holes. Also, you get a smooth cut fast and easy.

In terms of speed alone, this is not quite as fast as the more expensive brands, but it still does a decent job, and that's the only compromise you're making when going for this lesser priced product.

However, do keep in mind although we recommend this for professional application, this is still mainly for light jobs. If you use this for extensive puncturing, you might overwork the bits and break them.

With that said, for the price, the value for money is as good as you can get. And top it off with the decent build and fast use, this is a pretty decent bit to add to your collection.

Step Drill Bit Buying Guide

Step Drill Bit Buying Guide

Step Drill bit aren't probably the first bit you're using. And these tools stand among the bits which aren't used very often- as a result, most people don't know much about them.

So, we will discuss the features and facts that you ought to check in order to buy the best step drill bit for yourself.


This is common for any bit you buy. How effective a bit is going to be, or will it break apart even before denting the sheet, depends somewhat on the material used for its makings.

For step drill bits, HSS or high-speed steels are good for thinner sheets like plastic, aluminum, and other soft metals.

But when you need to pierce through tougher sheets, you need a stronger material like cobalt. However, don't blame it all on the material even if they break down because, more often than not, it happens because of the wrong application.

Drill Bit Shank

Now we bring shank right into the mix because if the shank doesn't match with the power tool you own, then buying it will be a waste. Do check the compatibility of the shanks with your tool. It's usually mentioned in the details or on the packaging.

Another thing to notice on the shank is its shape and quality. Flimsier shanks might make using the bit shaky and will result in the hole being rougher as well.


Titanium is the most popular finish used for step drill bits. It is also what separates this type of bits from the lot. The titanium coating reduces the friction between the surface and the bit and makes piercing easier for it.

Size Options

Step Drill's main advantage is that they give a range of options. So, the more size options you can find, the diverse range of work you can do with the bit. This increases the potential of the tool and gives you more to work with.

Size Marks

One of the main reasons why step drills are popular is because they have size marks imprinted on them. When you need to drill a hole to fit in screws, you want them to have a specific size, and that's where the necessity of the size marks come in.

So, we recommend bits that have laser indentations instead of other kinds of marks. With other kinds of the mark, they might fade out and make it difficult to view.
