Good Drill Bits Buyer’s Guide
The different types of materials that drill bits are made out of and the finishes that are applied during the manufacturing process all play an important role in the performance and longevity of the bit. The type and style of bit you choose will ultimately depend on the project and the type of material you want to drill into. If you use the wrong type of bit, it may break, if it’s not tough enough to drill through the intended material, or it may damage the material itself. You’ll also run into performance issues with your drill, since it may start to overheat in an attempt to power the bit through the material. As you can see, there are many things to consider before you purchase new drill bits. Below, I’ll go over the different types of bits available, their pros and cons, and what type will work the best for you based on material and application.
Types of Drill Bits
As I mentioned above, there are a variety of styles of bits to choose from, each of which will play an important role in your job, depending on the type of material you’re drilling into.
HSS, or high-speed steel is a type of bit that’s designed to drill into PVC, fiberglass, and wood. It can also handle drilling into certain types of softer metals such as aluminum.
This is a very tough bit that’s specifically designed to dissipate heat instantly. This type of bit is commonly used to drill through tougher materials such as stainless steel, however, it can also be used to drill into softer materials such as aluminum.
HSS with Black Oxide
This style has a finish that’s designed to increase its durability while providing some protection against corrosion. These bits tend to last much longer than many other types of bits and can handle drilling through many different types of materials such as fiberglass, PVC, aluminum, wood, and certain metals.
HSS with Titanium Coating
This bit is designed to produce less friction. It’s considered hardier than the standard HSS bit and is designed to remain sharper for a longer period of time, so you’ll definitely get more use out of it. This type will work well for drilling PCV, soft metals, hard metals, wood, and fiberglass.
Drill bits with a carbide tip are another variety that is designed to stay sharper for longer, even when compared to titanium or standard HSS bits. They’re widely used for both masonry and drilling through tile.
These bits are probably the most common type of bit used since they’re very versatile and very affordable. They can be used on almost any type of material including light metals, plastic, and wood. This bit features edges located on the front, designed to cut material, while its spiral design will get rid of any type of debris that comes out of the material.
This bit is considered very versatile, especially the type that features high-speed steel, which is what allows you to drill into many different types of materials. They can also come with a type of titanium nitride coating which has a similar appearance to gold. This additional coating will increase its durability by adding a protective layer that will prevent the bit from breaking when you’re working on tougher metals. It’s also available in a variety of sizes that range from half a millimeter up to twelve millimeters. These bits will work better for smaller hole sizes. Additionally, if you use it on greenwood it can clog, so constant debris removal with this type of material will be important.
This style of bit is specifically named due to its shape, which is stair-like. It can be used on a wide variety of materials, but it’s best-suited for plastic and aluminum.
These bits are designed for use on softer materials and wood. Its point provides better than average accuracy and allows the user to drill cleaner entry and exit holes.
The auger bit is perfect for use on soft and hardwoods. It comes equipped with a screw top that allows it to drill cleanly through. The unique design will also allow the user to remove material for a much cleaner cut.
This bit comes with a very simplistic design and it’s best suited for softer woods. These bits are very affordable and are often used for tough construction jobs, such as drilling holes for joists.
This type of bit is perfect for soft wood use. The bit comes equipped with a point in the center and a flat bottom, both of which provide increased accuracy. This type is a great option for the woodworker.
This is another unique bit and one that features a circular shape. These bits are a great choice for cutting precise, large circles into thinner materials. They can also be used for drywall or light installations.
This type can be used in wood only. However, they’ll definitely come in handy since they essentially allow you to countersink fasteners.
These bits provide a durable construction and fast hammering action, so they’re often used for materials such as bricks, and concrete and are a staple for most masonry work. This bit is coated with tungsten carbide, which is bonded to a spiral shaft that’s made out of steel. Some manufacturers may also use a type of silicon bronze alloy instead of tungsten for the cutting point. However, this type is not very popular. While you can use this bit for power drills, they can also be used with hand braces. Regardless of how you use the bit, you’ll need to be very careful since increased pressure tends to damage them, which can cause them to shatter if the drill’s action power doesn’t offer enough resistance. When you’re working with tougher materials, make sure you use a slower rotation speed to prevent overheating.
Top Drill Bit Design Explained
The angle of the point of the drill bit is designed to determine what type of materials it’s capable of drilling through. A bit that has a flat point is designed to handle tougher materials. A bit with a steep point is perfect for softer materials. These bits are designed to remain on the center much better than a flat pointed bit, which is why they often produce a much cleaner looking exit and entry hole. Bits that have a tip that’s split is designed to improve drilling accuracy. The split design will prevent the bit from wandering off the target. This also results in cleaner exit and entry holes.
Other Important Features
As you can see, there are several types of bits to choose from. Having to stop a project because you didn’t purchase the right type of drill bit can be very frustrating, which is why it’s important that you do your research prior to starting a project, to ensure that you purchase a basic set of bits and any specialty bits needed, based on the application and the type of material you’ll be drilling into.
There are many things to consider before you purchase a single or set of drill bits. You’ll need to choose the type of bit based on what type of material you want to drill through, the size of the bit, and you also have to choose a bit based on the type of drill you have, since not every bit will work for every drill. Let’s take a look at some of the other features you’ll need to learn about before you start shopping around.
The size of a bit will reflect the diameter of the bit’s body. You’ll come across certain projects that will require drill bits of a specific size. However, most sets will include a variety of sizes that are designed to handle most jobs in the garage and around the home. If the set you purchase doesn’t come with the size you need, you can always purchase it separately.
The chuck on a drill press or hand power tool will secure the drill bit in the shank. Smaller drills are used for work around the home and often come equipped with a chuck that measures in at 3/8 of an inch. Heavy-duty hand drills will have a chuck that measures in at half an inch. The average drill press will have a chuck that’s significantly larger, starting at half an inch.
Drilling Tips and Tricks
- For general drilling jobs, you’ll want to use a twist bit, or an HSS bit.
- When you’re drilling plaster, slate, or brick, you’ll need to use a bit designed specifically for masonry. Adjust the drill to the lowest setting.
- For glass and tile, use a lower speed and a bit with a spear point.
- For larger holes, go with a hole bit. However, be sure that the drill you have is able to handle this type of extra force or you may end up burning out the motor.
- For tougher metals, using a step bit will be your best bet, placed on a lower speed.
A drill bit is what makes the bore or cut into your work. Because of this, I recommend spending more and investing in high-quality bits. These bits will last much longer than low-priced bits so you will save time and money in the long run.
Frequently Asked Questions
Is Cobalt or Titanium Drill Bits Better?
The titanium coating on the bit can make a huge difference. As an example, the titanium coating can easily handle tougher materials compared to a standard HSS, but it shouldn’t be used for harder materials such as stainless steel, whereas the cobalt bits are better for the toughest materials such as cast iron or another type of material that’s considered very abrasive.
Can You Sharpen Cobalt Drill Bits?
Yes. These bits have a higher than average resistance to heat, which is why they’re perfect for repeated use. Over time, these bits will need to be sharpened as the edge becomes dull. If you have a grinder, then you can sharpen them yourself.
Is it Worth Sharpening Drill Bits?
You’ll need to use a bench grinder to sharpen bits. There are some types of tools that are specially designed to sharpen bits, but they’re very pricey. If you’ve invested in high-quality bits, then sharpening them will allow you to get more use out of them, however, for low-priced bits, you’re better off tossing them and purchasing new ones.
Final Thoughts on Selecting Top Dril Bits
There are many different types of bits to choose from, based on application and material type.
