7 Best Step Drill Bit Set

The step drill parts are the parts that allow drilling holes of different sizes with just one part. It increases gradually as you lower the bit. Generally, it looks like a cone shape to drill various holes without changing bits.

The best step drill bit set always depends on its metal. Titanium and HSS (high speed steel) drill bits are suitable for aluminium. Certain alloy and higher amount of fibre-glass are waste of money. 

The right cutting fluid has a miraculous effect on all drill or cutting material combinations. Carbide parts are an essential step in drilling harder metals and joints. 

Moreover, the bit tip requires more force and creates additional heat to the workpiece and end. If possible, compare the energy applied with a drill of a similar size for each tip type.

Factors to pick the Best Step Drill Bit Set

A drill bit is a great tool you should have in the arsenal. Whether you are a regular do-it-yourselfer or a weekend do-it-yourselfer, you may likely use your drill more often than any other essential power tool. So, find out what to consider before buying a step drill bit set.

Dimension Marking

Dimensions printed on the body make the step drill bit so popular. When you drill your hole to drive screws, you may always go for the specific size where size marks are needed.

That’s why we recommend laser-cut bits instead of other types of markings. With different types of markings, they can become dull and difficult to see.

Shank of the Drill Bit

Now we turn the shank directly into the mixture because if it does not resemble your power tool, it’s a shame to buy it. Check the adaptability of the handles with your instrument. 

Also, consider the quality and shape of the shank. Weaker shanks can make the part unstable to use and also make the hole rougher.


It is applicable for every bit you purchase. The product’s effectiveness, whether it breaks even before the blade hits, depends to some extent on the material from which it is made.

High-speed steel (HSS) is suitable for step drills or thinner coats such as aluminum, plastic, and other soft alloys. But if you have to drill more brutal slabs, you must need a more substantial material such as cobalt. 

However, you should not blame the material for everything, even if it breaks. That’s because, in most cases, this is due to improper application.

Size Choices

The main advantage of Step Drills is that they offer many options. Thus, the more options for the size you get, the more varied work you may do with this item. It extends the capabilities of the device and gives you more opportunities to go with it.

Finishing Component

Titaniums are the most traditional finish for stepped drills. Also, this separates these types of bits from the batch. Titanium coating lessens friction between the bit and surface and makes piercing more natural.

How to choose the Right Drill Bit?

Understanding what drill bit utilizes and when to use it increases your chances of correctly getting the task done the first time. As these instruments have so many applications, various drill bits are available, each dedicated to a distinct purpose. Understanding what they all accomplish will go a long way toward ensuring the success of your project.

Here’s how to pick the best drill bit for your job.

Materials for Quality Drill Bits

Black Oxide-Coated HSS: Because of its coated finish and resistance to wear, Black Oxide-Coated HSS Drill Bits outlast other high-speed bits. They are far more durable, and they work well with various materials, including metal, hardwoods, softwoods, fiberglass, and polyvinyl chloride (PVC).

Steel bits: They are less expensive and are often used with softer woods. They wear and dull fast and can occasionally shatter, mainly when used with more hardwood products.

Titanium Coated Bit: These are more costly than high-speed steel bits, but they last longer, are more demanding and keep their sharpness better. They are most effective when used with metal, wood, fiberglass, and polyvinyl chloride (PVC).

High-Speed Steel (HSS): These bits are trickier, stay sharper for extended periods, and drill soft metals, PVC, wood, and fiberglass.

Carbide-Tipped Drill: These Bits are more expensive, but they keep their sharpness longer than any other bit.

Cobalt Drill Bits: These are difficult to use and quickly dissipate heat. They are employed in the penetration of more critical metals such as stainless steel and aluminium.

Size of drill bit

Drill bits come with pilot hole charts to assist you in selecting the correct bit for the job. These formulas are based on the screw shank and should only be used as guidance:

  • If you’re unsure, go with a drill bit that’s 1/64″ larger than the hole you want to make. This takes into consideration things like wood density and screw type.
  • When working with other materials, use a bit that is the same size as the hole.
  • For softwoods, use a bit that is 1/64″ smaller than the required hole size.

Benefits of Step Drill Bits

If you’re still not convinced or unsure whether to use a step drill bit instead of a standard bit, let me help you by outlining the advantages.

It has an excellent drilling accuracy; even a minor decline is noted only in holes more prominent than 15 mm. Because of the improved strength of the cutting surface, you will have a more comprehensive working resource.

It is capable of drilling holes in hard materials without sacrificing quality. Another advantage of utilizing a step drill bit is its sharp cutting edges that provide smooth-walled and straight hole sidewalls. It removes the necessity for the centering tool to be used during the preliminary process.

As step drills are created as different sizes in one tool, there is no need to attach, remove, or reattach the bits while drilling. It can drill holes at fast speeds without sacrificing the quality of the hole’s edges. You will have the option of creating a so-called triangle hole.

How does a Drill Bit work?

A drill bit is a type of cutting instrument used to create or expand holes in solid metal. These are used in conjunction with a chuck-equipped manual drill or drill press. To tighten or loosen the clamp on these drilling machines, a key is used.

Every drill necessitates using a source of power, which we’ll refer to as the machine. Electric motors with a speed-adjusting gearbox often power a modern residential DIY drill. Massive diesel engines or pneumatic compressors power outdoor drilling rigs.

The drilling bit is the revolving, cylindrical instrument used to cut or bore into the drilled material. Drilling creates a lot of heat, harming both the material being drilled and the drill itself.

Additionally, drills have replacement bits that exist in a wide range of different and exact lengths. Drill bits are frequently designed so that cooler fluid (even sometimes regular simple water) can be directed to the sharp end.

For instance, when drilling a metal hole, burrs (sharp metal edges) are forced into the pit and appear at the exit pit, where they must be detached using a file. When drilling a pit on a subway or metro tube, it is usually necessary to strengthen it with concrete to prevent collapse. The same may be said for simple holes drilled in your home’s walls.

FAQs on Best Step Drill Bit Set

What is a step drill bit most useful for?

A step drill bit is often used for drilling holes or expanding existing holes in soft materials. They can also drill in plastic, thin sheet metal, aluminum, and hard materials like cast iron, bronze, and steel.
Step drill bits, once again, drill into any metal sheet up to ¼” thick by spinning clockwise. As most step bits don’t need pre-holes or pilot holes, it is renowned as a self-start drill bit.

Are Step bits good for metal?

As step bits do not twist, they are ideal for drilling through sheet metal and other thin, stiff materials. As you proceed through the steps, they gradually shave off material and create progressively bigger holes.
A standard drill will catch as soon as the bit begins to enter the metal. That will most likely snap the drill bit or result in an intense backlash. That is not an issue with a step drill.

Can step drill bits be used on wood?

Step drills are perfect for cutting plastics, metals, and wood up to 4 millimetres thick and stainless steel up to 1.5 millimetres thick.
They are intended chiefly for thin or sheet metal up to 1/4 inch thick. Surprisingly, you may also use them on wood and other materials such as plastic or metal. So, if you’re going to use them on wood, make sure it’s up to a maximum thickness of 4 millimetres.

Can I sharpen a step drill bit?

Any step drill bit will get dull with usage; thus, you should regularly polish the tip and flute for the most outstanding performance. You may sharpen it with a specific sharpening attachment or with a regular bench grinder. Hold the shank firmly with one hand so you can rotate the drill while supporting your torso with the other.
Make a 45-degree angle with the drill tip to the grinding wheel. To a wheel, apply a leading or cutting edge.

How thick of metal can you drill with a step drill bit?

Step drilling bits are used to make holes in thin materials like sheet metal. Whether you require a correctly sized electrical service panel, a neat hole in a metal junction box, or a stainless-steel sink, these are the instruments you employ. A metal step drill bit enables you to drill holes of changing diameters, and many will drill through metal as thick as 3/8 inch.

Final Verdict
