It is made of high-quality carbide grit, which gives it the power to hold up to abuse for extremely long. Many users that have tried out several brands can tell you that this one lasts even 10 times as much as most other saws.

When the pilot drill cuts through material, the carbide teeth impact. This is one of the factors that make metal drills wear quickly.

But with this particular drill, the pilot drill features a stepped design. That way, the carbide teeth are protected from impacting.

And like that, the longevity of this unit is boosted.

Ever used a hole saw that made very rough and ugly holes? Such a saw can be quite annoying because apart from making holes that are unsuitable for the intended purpose, they are hard to use.

Buying Guide on Purchasing the Best Hole Saw for Stainless Steel 

There are lots of manufacturers these days that make hole saws. While this is good for giving us many options to choose from, it might leave you confused.

To avoid the confusion, there are several factors you should take into consideration when looking for the best hole saw for stainless steel.

  • Sturdiness

Sturdiness will be defined by the material that the unit is made of. Hole saws have two parts – the body and the tip. It’s okay for the body to be made of ordinary steel, but the tips should be made of something harder like black oxide, carbide steel, or cobalt steel. These materials will bore you more holes before they finally become dull.

Tungsten tips would be better if you can get them, but these are costlier and more suited for professional use.

  • Compatibility with powered drills

Hole saws don’t usually come as complete units with a drill attachment. They usually come as bits meant to be attached to drills.

It makes sense to get bits that are compatible with the handheld-held drill, mobile magnetic drill, vertical drill, and more. This is especially crucial if you’re a professional.

  • Replaceable parts

When the pilot drill wears out, that doesn’t have to mean that your hole saw set becomes obsolete. But then again, that depends on whether the pilot drill is replaceable.

Ease of replacement is an important factor to look at. Make sure the manufacturer has stated that they sell replacement parts to extend your kit’s lifespan.

  • Drilling efficiency

Though I have written this factor last, the truth is that this is the most important feature to look out for when shopping for a hole saw for metal. You want a hole saw that works and drills clean holes according to your needs.

Go for a good unit with a good performance. The saw should be able to make precise cuts that are clean so the cleanup afterward is not too much. Sharp teeth are essential if the efficiency is to be high.

Listen to what people say (or read reviews like the ones in this article) to find out how well the unit drills. It should be able to accomplish the work quickly and without too much effort or splatter.

How Do You Drill Through Hardened Steel?

If you’re a DIYer, it is almost certain that there’ll be a time when you need to make a hole in a piece of metal. In this section, I am going to spell out tips that will help you use a hole saw to drill holes through metal.

Let’s jump in.

  • Wear protection gear

Drilling metal usually sends splatter flying around. All it takes is one of these little fragments to reach your eyes, and you’re looking at a serious medical emergency.

Why go through the pain?

Wear suitable googles to protect your eyes. Go for safety googles that wrap around the sides so there’s no entry point for the splinters.

  • Create a dimple

If this will be the first time you bore holes through metal, there’s something you might not know. It is the fact that when drilling metal, the drill bit can wander a lot at first. This can make an irregular hole, which is not what you’re hoping for.

Making a dimple will prevent that. Use a hammer and a center punch to create a dimple on the point where you want to drill the hole. This will give your drill bit a spot to hold on to and prevent the wandering.

And that way, your hole will be just as you pictured.

  • Lubricate

Drilling holes on metal without lubricating is a bad idea. Why? It increases the friction between the drill bit and the metal. High amounts of heat are generated, making the drilling process harder. An even more critical problem is that it causes the drill bit to wear faster.

Therefore, be sure to lubricate the drill bit with a suitable oil like multipurpose oil or cutting fluid.

  • Clamp the workpiece

I have seen some people hold with one hand the piece they’re drilling while trying to drill with the other hand. That is dangerous, not to mention inefficient. What if the drill bit to catch and the workpiece spins out of control? If there are sharp edges on the workpiece and they come into contact with your body, you can only imagine the pain.

If the workpiece is not heavy and stable on its own, use at least 2 clamps to hold it in place.

  • Begin with a small hole

Maybe you want a wide hole, say 1-1/8 inches. If you want the best results, begin with a smaller hole, perhaps a ¾-inch. From there, drill successively bigger holes till you get to the size you’re looking for.

  • Use low speeds

High speeds will drill fast and help you finish the work quickly, right? While that may be true, it presents a drawback you can’t afford to put up with – it dulls your bit quickly.

Thus, it’s recommended that you use as slow speeds as possible when drilling metal, especially if it is hard metal like stainless steel.

Try sticking to speeds between 350 and 1000 RPM. The harder the metal, the lower the speed required.

  • Try a wood sandwich for cleaner projects

If you’re drilling through a thin metal sheet, and would like the hole to be very clean and precise, you’ll find a wood sandwich most helpful.

Just sandwich the metal sheet between two pieces of wood and clamp the whole thing down on a workbench.

The wood pieces will ensure the metal sheet stays flat and make sure your drill bit does not wander as it creates the hole.

  • Clean the hole

Once you’re done boring the hole, the process doesn’t stop there. You got to remove any burrs or sharp edges created. There are two options for this.

The first one is to use a larger (in diameter) drill bit than the bore you just created. Just hand-twist the bit gently over the hole to smooth out the edges and remove the burrs.

The second one is to use a deburring tool. These are available online and work better to smooth out sharp edges.

How Is a Hole Saw Measured?

Before buying a hole saw for cutting stainless steel, the size is one of the paramount factors to take into consideration.

These tools come in a variety of sizes, going from ½ inch to a little over 8 inches wide. Some of them have their size written on the cutting blade.

Well, here are the common ways of sizing hole saws:

  • Diameter

The diameter of the hole you’re boring is likely the most important size.

As stated earlier, most units have a diameter going from ½ inch to around 8 inches. But a majority of people don’t need large diameters. The most commonly used diameters go from 9/16 inches to 3 inches.

These are ideal for boring small holes on pipework, sinks, and cable boxes, and other items at home.

The 2-inch saw is a popular choice for making holes on desk surfaces for computer cables to pass through.

For light fittings and drainage pipes, larger diameters, around 4 to 5 inches, tend to be the preferred choice.

Diameters larger than that are seldom used at home. These are more suited to professional work at industrial levels.

  • Cutting Depth

This refers to how deep a hole saw can bore without using an arbor extension or breaking off the slug. The cutting depth is directly proportional to the saw blade length.

Models can have a cutting depth anywhere between 5 and 350 mm.

Note: if a unit is stated as having a cutting depth of 5 mm, that essentially means you can bore holes that are up to 10 mm. that’s because you can flip the workpiece over and bore from the other side.

If you need more depth, you can always use an arbor extension.

Frequently Asked Questions (FAQs) 

  • Will a hole saw cut through stainless steel?

That depends on the material it is made of. A good hole saw made of resilient materials like cobalt steel will cut through hard materials like stainless steel. In addition, it will easily cut softer materials like wood, PVC, and plastic.

  • Will a diamond hole saw cut steel?

Diamond saws are not as tough as they might seem. When you try using diamond to cut steel, especially hardened steel, the saw becomes clogged with steel and fails to work.

Diamond saws are more suited for softer materials like porcelain tiles, PVC, plastic, wood, and concrete.

  • Can hole saws cut through metal?

Yes, there’s a whole assortment of hole saws made just for metal. But to cut efficiently, it is recommended that you use low drill speeds. The idea is to minimize friction and the subsequent heat, keeping in mind that metals like stainless steel become harder when heated.

Final Thought about Best Hole Saw for Stainless Steel

Friends, we have come to the end of the review. At this point, I hope my work have proven helpful.

Remember, getting the best hole saw for stainless steel rests on one aspect – your needs. For instance, there’s the size that will fit your needs depending on the projects you have in mind.

But considering you may not want to bow the same size of holes all the time, I would encourage you to go for a kit that comes with saws of different sizes.

That way, you stand a better chance of handling whatever project might come your way.

Be sure to get a model that is strong and sturdy enough for your needs. Carbide and cobalt steel are two popular materials that many people find useful for boring through metal, wood, and other items.
