Are All Drill Bits The Same?

Companies nowadays have introduced universal drill bits that can be used for various surfaces such as concrete, brick, or wood, and are available at many hardware stores. However, these are not 100% universal, since these drill bits can be inappropriate for surfaces such as glass or ceramics. So, unless the surface is fragile, you won't actually need a separate bit for different surfaces. However, high-quality drill bits are expensive and need to be taken care of because they are an investment and can wear out quickly if not maintained. 

How to Choose Drill Bits

When finding the correct drill bits, you essentially want to look for the speed and the time-saving aspect of the drill bit, so you penetrate the wall easily. If you are a novice at drilling, this guide might be helpful for you to figure out how to spot the drill bit that aligns with your preferences.

Wood Drill Bits

These can be recognized by their sharp, pointed end and spurs on the sides. These are good for carving wood. Steel bits work well with softwood varieties, while a titanium-coated wood drill bit is the most durable. Overall, these bits are really nifty and common. 

Masonry Drill Bits

These kinds of drill bits slope towards the end and are often coated with carbide, to extend their sharpness. They work best with tile, stone, and cinder block. They are also very long-lasting and robust.

Metal Drill Bits

The tip of this drill bit is wide-angled and often comes in black. If you are to purchase a metal drill bit, make sure there is a label that indicates it is made of high-speed steel (HSS). They are also quite multipurpose.

PROS

  • Functions well with tougher materials
  • Sturdy and long-wearing cobalt HSS
  • Comes with a rubberized, over-molded case
  • 8% of cobalt alloy is heat and abrasion-resistant
  • Reduced shank on top of the 3/8-inch mark allows you to use bigger drill bit in 3/8-inch chuck

CONS

  • Inserts are created with plastic and can wear out easily
  • Without a hex, in a battery-operated hand chuck, drill bits get caught in the drill and keep spinning around

What Recent Buyers Report

Consumers find this product to be very good quality for the money. It cuts through surfaces like a hot knife slicing through butter, and gives fine, clean cuts. They are also super-sharp and produce accurate curls, satisfying most users.

Why it Stands Out to Us

One reason this product is so great is that it is abrasion-resistant when drilled into hard or rough metals. The cobalt bits are extremely powerful and sturdy, making them durable and good as new once they are sharpened, making this unit stand out.

Who Will Use This Most

This product is specifically designed to drill into hardened steel. Which means this heavy-duty drill bit set is a great option for workers who have a lot of intense construction projects and need something of great quality that doesn’t wear out.

Bottom Line

These high-speed steel drill bits, with an 8% cobalt alloy for increased heat and abrasion resistance, work flawlessly for hard bolts and for other heavy-duty purposes that cannot be done with standard drill bits. This 29-piece drill bit set is surely an investment for a lifetime.

Why it Stands Out to Us

All the pieces in the set are of top-quality and high-speed with a titanium coating that adds a wow factor to these drills. It keeps them shiny, glossy, and ensures extreme durability for many years, so this product is definitely an investment. The casing allows for the bits to be carried anywhere and has a great shelf life.

Who Will Use This Most

Since this set is not suitable for tougher and harder metals, it would not be appropriate for workers who have heavy-duty projects and tasks. However, it is for those who have softer tasks, such as home DIYs and are looking for ease and convenience.

Bottom Line

Dewalt does not disappoint with this high-performing drill bit set. Introducing titanium pilot points that start on contact, these heavy-duty bits are designed to avoid walking, and the no-spin shank is an added bonus. It also comes with an organized carrying case and is overall, a great investment.

Why it Stands Out to Us

Drill America introduces its 29-piece, 1/64-inch incremental bits built to perform on an extensive assortment of surfaces, especially iron and steel. The gold oxide appearance aids in lessening friction.

Who Will Use This Most

The gold oxide finishing makes coolant pockets near the cutting edge that solidify this drill bit's usage for boring into rough, solid metal materials for construction projects, maintenance such as fixing or repairing, and portable work. They are also a great tool for those working in the auto industry.

Bottom Line

The rock carbide tip helps to maintain the longevity of the product and makes it an outstanding drill bit set for concrete drilling.

Why it Stands Out to Us

An amazing feature of this drill bit set is the fact that it is powerful and can penetrate concrete easily. It is also super-durable and you can use it for many purposes, on the condition that you take care of it. When discussing the design and material, this drill bit set has rock carbide bits for durability and high-quality performance.

What Recent Buyers Report

The diamond-coated tip works like a dream on porcelain tiles and is inexpensive. They are also much better than carbide because rather than cutting through the tile, they penetrate and push through to ensure you do not have a fractured tile.

Why it Stands Out to Us

The working of Neiko’s Diamond Grit Hole Saw Drill Bit Set is of greater quality and performance compared to that of a conventional carbide hole saw drill. The bits are coated with an extra layer of nickel to avoid any corrosion from taking place. It is a great product that cuts holes in a wide variety of materials such as plastics and glass with great precision and accuracy.

Who Will Use This Most

This five-piece set is pretty versatile if you are looking to improve your home. It’s also great to use in construction projects or for professional use around the home, as well. It works on porcelain, as well as glass and ceramics.

Why it Stands Out to Us

The Neiko bits are made of HSS with a titanium coating and have a 135° split-point tip. They work outstandingly well if you want to use these bits for drilling holes in plastic, aluminum, copper, stainless steel, and many different varieties of sheet metal.

Who Will Use This Most

What Recent Buyers Report

These drill bits work like a dream if you want to drill into softer materials and reduce the time it takes for step-up-bit cutting. They also eradicate any tear-out issues and are super-convenient and handy if you work with plastic regularly.

Why it Stands Out to Us

The drill bits are pretty sharp and easy to use, and perform flawlessly on plastic or acrylics without damaging the material and causing any cracks or tears. The edges on the holes also remain chip-free and the finish is very smooth.

Who Will Use This Most

This kind of drill bit is a great option for users who have handheld applications, a drill press, or even automated machines. A good drill bit is necessary for such fragile surfaces and if you work with plastic a lot, this is the best option for you to consider.

Bottom Line

Types of Drill Bits

Drill bits are the main component of a drill and there are many designs out there for every kind of surface and for every particular need. Let’s dive into some of the types available in the market.

High-Speed Steel (HSS) Bits

These are the most popular kind of drill bits designed for everyday use, such as drilling into wood, metal, or plastic surfaces. Usually, they have a cylindrical shank, but sometimes they can be hexagonal, as well. They are compatible with impact drivers and cordless screwdrivers for small, less intense tasks.

Masonry Bits

These drill bits are used in hammer drills for boring through concrete, stone, and bricks. The expert drill bits have a hex-shank rather than a standard cylindrical one to stop bits from slipping in the chuck. Such bits require a lot of pressure and that’s why they can heat up quickly during use.

Cobalt HSS Bits

These drill bits are created from solid cobalt alloys and are highly resistant to abrasion and high temperatures. They are used to penetrate through surfaces such as stainless steel or other high tensile steel types, such as cast iron.

Conclusion

Now that you know the different kinds of drill bits and what they’re used for, it will be a little easier to choose which drill bits suit your needs most and are more applicable for your project or task. Hopefully, this review was detailed enough to give you a good guideline on what type of drill bit set you should buy.
