Buyers Guide for the Best Drill Bits
So it’s time to start looking at the best drill bits for your projects. We have listed five top choices. There are a lot of factors to consider when making a choice. In this buyer’s guide, we will outline what to look for in a high-quality drill bit so you make the best choice.
What to Look for in a Drill Bit
There are several things to consider when making a drill bit choice. Of course, you want durability and affordability, but there are other things to think about before finalizing your purchase.
Material Used to Construct the Drill Bit
Steel is the most common choice for affordable drill bits because it’s not very expensive. It works well on softwoods. High-speed steel is much harder than standard steel. Bits fashioned from high-speed steel can easily drill through harder woods, PVC, fiberglass, and aluminum. If you are looking for something to saw Wood instead, please head over to our guide here.
- Titanium coating doesn’t produce excessive friction like steel, even when used at high speed, meaning it doesn’t heat up as much.
- Carbide tipped bits are highly durable and hold their sharpness longer than steel or high-speed steel. You can use them to drill through concrete, masonry, or tile.
- Black oxide coating is used for a general-purpose steel blade. The coating makes the bit resistant to rust or corrosion.
- Cobalt is a powerful bit that is often used to drill through steel or iron.
You’ll want to pay attention to two sizes on the drill bits: the shank and the point. The shank of the bit goes into the drill’s chuck. You’ll need to find drill bits that have shanks equal to or smaller than your drill’s chuck, or they won’t fit. Standard chuck sizes run from 1/4 of an inch to light-duty drills that are 3/8 of an inch. A heavy-duty drill usually has a 1/2 inch chuck.
The bit’s pointed end is what drills through materials. It can range from 1/16-inch to ¼-inch for common household projects. However, if you work in construction or carpentry, then you might need a larger bit. Common bit sizes include the following: 5/16-inch, 3/8-inch, 7/16-inch, and 1/2-inch. It’s always good to have one of each in your tool kit, so you’re ready for whatever task you face. There’s nothing more frustrating than stopping work to run to the hardware store to buy a new drill bit.
Types of Drill Bits
When shopping for the best drill bits, you’re going to encounter a large assortment of bit types. Some you might need and others you may never use. Let’s look at the most common types of drill bits you should have in your toolbox or shop. Drill bits are made from a variety of materials in different designs.
- Twist: This is a widespread type of drill bit favored for general purpose drilling into materials such as light metals, wood, or plastic.
- Space: The bit resembles an oar with a little point. You can drill huge holes with this unusual-looking bit. Many people use it to drill through materials like wood.
- Auger: This bit is long and has a twisted ribbon pattern that looks like a screw. The tip is sharp and will readily pull the bit through materials like wood with ease.
- Brad: This bit’s point features a slightly larger and looser twist. This bit is made for wood materials and makes huge, neat holes.
- Forstner: This classic drill bit is used to drill flat-bottomed holes that never go all the way through the wood.
- Countersink: Many refer to this bit as a screw pilot bit. It’s used to make pilot holes so that the screws sit flush against the wood’s surface.
- Masonry: The masonry bit is the toughest of the tough. It will drill through masonry, rock, cement, and concrete. The drill bits are large and powerful.
- Glass: Yes, you can buy a specialty bit that lets you drill through glass without shattering the breakable material.
- Tile: Speciality tile drill bits drill through ceramic tile without chipping or causing cracks.
- Step: The bits are shaped like a round arrowhead. They are favored for drilling through metals.
Drill Bit Coatings
Many drill bits that you purchase will feature a coating. Below is a list of the most common kinds of coatings and their benefits.
- Black Oxide: The black oxide coating is placed over a steel bit to prevent corrosion and help reduce friction. It’s suitable for materials such as wood, plastics, composites, or soft metals. Unfortunately, drill bits coated in black oxide do not stay sharp for very long, and the coating will quickly start to wear down. Unfortunately, when a black oxide drill bit goes dull, you have to throw it away because it cannot be sharpened.
- Titanium Nitride Coating: Titanium nitride is often used in place of black oxide. Its purpose is to extend the life of the drill bit by helping it combat corrosion and friction. It also helps make the bit harder and provides an impressive thermal barrier against heat buildup. Titanium-coated drill bits last longer than black oxide-coated drill bits. A titanium drill bit will also drill far faster than a black oxide bit – the chips move through the bit’s flutes easily. The only disadvantage to a titanium nitride drill bit is that the coating does wear off in time. Titanium-coated drill bits are a great choice for metal and wood drilling projects. However, they don’t work for concrete.
- Cobalt (Steel Blend): A cobalt drill bit is fashioned from five to eight percent cobalt. The cobalt is actually formulated into the steel blend, so it doesn’t wear off like a coating. You can even sharpen these bits when they become dull. Cobalt drill bits are a little higher priced, but they become well worth it to most people seeking to purchase the best drill bit set for the extended life span. Another nice feature to note is that cobalt bits can drill through just about anything. They are impressive for metal drills, even cast iron. Drill bits made of cobalt are ideal and even better than hardened steel in many cases.
FAQ About the Best Drill Bits
Let’s take a look at the most commonly asked questions about drill bit sets and drill bits.
Can Drill Bits be Sharpened?
Yes, you can sharpen some drill bits, such as twist drill bits. Sharpening regularly helps maintain the bits and makes them far more effective at completing their task. Also, keeping a drill bit sharp makes working with the drill safer because a sharp drill bit is less likely to slip or skid when you try to drill through hard materials.
You can purchase electric drill bit sharpeners that will quickly restore sharpness. You can also use a bench grinder or rotary tool to sharpen drill bits. If you want an affordable way to sharpen a bit, then invest in a basic metal sharpening file and carry out the task by hand.
Are All Drill Bits Universal?
Drill bits can usually be used on any brand of drill as long as the bit fits the drill’s chuck. Remember, the chuck is the drill part that clamps onto the bit and holds it in place—most chucks measure ¼-inch, ⅜-inch, and ½-inch. Remember, you cannot use a bit on the drill if the bit’s shank is larger than the drill’s chuck.
What Damages a Drill Bit?
Heat is the biggest enemy of any drill bit. The buildup of heat will quickly cause the cutting edges of the bit to become dull. If you drill at a slower speed, you can reduce heat. Any time you are drilling through hard materials such as concrete, masonry, rock, metal, or cement, you should be drilling at a slow speed to lower the heat. You can also invest in cutting oil lubricants which reduce heat. If you don’t have access to a lubricant, you can use light mineral oil to lower the heat.
Do You Have to Clean Your Drill Bits?
You can keep your drill bits in shape by regularly cleaning them. Just wipe the bits down using a clean cloth after each use. Always wait for the bit to cool down before you wipe it. You can always use an old toothbrush to brush away any stubborn dirt. It’s not uncommon for a drill bit to get sawdust or drywall dust stuck in the grooves.
If the drill bit is rusty, you can clean it by soaking it in white vinegar for 30 minutes and then use a brush to remove the rust. After soaking the bit in vinegar, be sure to wash away the solution before storing the bit.
What Exactly is a Left Handed Drill Bit?
Usually, drill bits twist clockwise toward the right. However, you can pick up left-handed bits that turn counterclockwise. These are old drill bits that were developed back when the drill did not feature a reverse switch function. You could use a left-handed bit in place of setting the drill to reverse manually. Nowadays, you might encounter left-handed bits that you can use to remove bolts or broken fasteners. You can also loosen a broken screw using a left-handed drill bit.
Owning drill bits is essential for your drill. The bits can help you complete a home DIY project, or you might need them professionally. Either way, you’ll want to invest in the best drill bit sets, so they last for years. A high-quality set might cost you a little bit more, but it’s well worth it for years of hard use.
