Editor's Rating: (4.6 / 5)

DeWalt DW1354 14-PC Titanium Brad Point Drill Bit Set
  • Quantity: 143
  • Material: Titanium
  • Size range: 1/16 - 1/2 inches
  • Application: Wood and metal

DeWalt offers this set of brad point drill bits for anyone who needs a high-quality drill bit set at a good price. They come coated with titanium and although they're not as tough as cobalt-coated bits, they still offer lots of value.

Titanium-coated bits last longer than ordinary steel bits, HSS bits, and even black oxide drill bits. In addition, they are brad point bits and so offer you more precision on both metal and wood.

There are 14 bits in the set, starting from a 1/16-inch sized bit, all the way to a 1/2-inch bit. All 14 bits come in a durable carrying case, which loads the bits on each side and includes a slide lock.

Pros:

  • Made from titanium for longer life
  • Features a titanium pilot point for cleaner holes
  • 14-pc set includes 1/16 to 1/2 bit sizes
  • Tapered web to cut down on breaking
  • Ideal for drilling both wood and metal

Cons:

  • DeWalt only offers a 30-day money back guarantee

#2. DeWalt DW1587 6-Piece Spade Drill Set 

Editor's Rating: (4.7 / 5)

DeWalt DW1587 6-Piece Spade Drill Set
  • Quantity: 6
  • Material: Black oxide
  • Size range: 3/8 - 1 inch
  • Application: Wood

If you're working with wood, then you'll need to quickly drill large holes from time to time and there's no better bit for large wood holes than spade bits.

These bits are made from black oxide coated steel, and this is perfect because spade bits are specially designed for woodwork, which often doesn't need very tough metals.

Each of the 6 spade bits features dual, precision-ground cutting edges for maximum speed and performance delivery. Like the set above, DeWalt only offers a 30-day money-back guarantee on this one as well.

The packaging is unimpressive though, and it doesn't come with a good carrying case, but it's priced really well and even comes with hex shanks for maximum torque delivery.

Pros:

  • Comes with 6 most popular spade wood bits
  • Easy to use bits for making large holes in wood
  • Bits come with hex shanks for maximum efficiency
  • Set's offered at an attractive price

Cons:

  • Doesn't come with a good carrying case

#3. Black & Decker 15557 Drill Bit Set 

Editor's Rating: (4 / 5)

Black & Decker 15557 Drill Bit Set
  • Quantity: 10
  • Material: High-Speed Steel
  • Size range: 1/16 - 1/4 inch
  • Application: Wood, plastic, and metal

Coming from Black & Decker, this 10-piece 15557 set includes the range of most widely used drill bits, ranging from 1/16-inch to 1/4-inch sizes.

They are from high-speed steel and this makes them usable in a variety of situations, including on metal and at high speeds because HSS is much more resistant to heat than ordinary steel.

High-speed steel is also very affordable and you can see this from the price of this offer for a pack of 10. For storage, you get a bit bar, which allows you to easily store this set anywhere.

The shanks are round and you can use the bits on wood, metal, and plastic, but not on masonry. Another disadvantage is that HSS bits don't last as long as titanium or cobalt bits.

Pros:

  • Package includes 10 drill bits for your convenience
  • Made from HSS for challenging applications
  • Includes the most popular bit sizes from 1/16 to 1/4
  • Offered at an extremely low price
  • Ideal for a 3/8-inch chuck drill

Cons:

  • Not ideal for masonry or tough metals

Editor's Rating: (4.2 / 5)

Bosch TI9IM 9-Piece Titanium Drill Bit Set
  • Quantity: 9 pieces
  • Material: Titanium
  • Size range: 1/16 - 3/8 inch
  • Application: Metal, wood, PVC

Bosch makes you an offer that's hard to resist with this TI9IM drill bit set. It comes with highly accurate no-skate tips for accurate starts and features a long-flute design for effective material removal.

These bits will also last twice as longer than comparable bits. They will drill wood, metal, and PVC, with their titanium coat creating less friction and their long flutes improving material removal.

Bosch rates the shanks impact tough, enabling them to last longer with high-torque impact drills and drivers.

It's obvious that the Bosch brand is one of the best drill bit brands around, but although this set is on offer at a very attractive price, it would have been better if a 1/4-inch it was at least included.

  • Material: Different materials
  • Size range: 5/64 - 1/2 inch

Pros:

Knowing Your Drill Bits

Different drill bits are for different purposes, so it's important that you can easily recognize each kind and to as well, know how best to work with it.

Following are different drilling situations and the ideal drill bits for them:

#1. Masonry Bits

Masonry Bits

For drilling into materials such as stones, bricks, and concrete, masonry bits are what you need. A masonry bit is usually designed for use with a hammer drill, to make the process easier.

Their tips are usually made from extra-hard materials to help the bits withstand the pressure of drilling into masonry. Tungsten carbide is a popular extra-tough material for making the best concrete drill bit tips.

You can identify a masonry bit by its twisted looking flutes, plus two or more prominent and strong cutting edges at the tip. They can come with a round shank or with an SDS shank, which is usually better.

#2. Wood Bits  

Wood Bits

For drilling into wood, there are three major types of bits you can use. These are auger bits, flat bits, and brad point bits. Each type has its advantages, as well as its disadvantages.

  • Auger Bits. These kinds of wood bits get used in drilling large and deep holes into wood. You can identify an auger bit from the screw at its tip and from the shape of its flutes.
    The auger flute features a helical screw blade which both helps to cut the wood and to transport it out of the hole being drilled. You need a powerful drill and good hands to handle auger drill bits.
  • Flat/Spade Bits. Referred to both as flat or spade bits, these bits get used in drilling very wide holes. They feature a pilot point tip to start the hole, plus a wider spade body to bore the larger hole.
  • Brad Point Bits. You can identify a brad point bit by the fine point in the middle of its end, with two sharp spurs on either side of the point. These two features give the brad point bit both a unique look and functionality at the same time.
    Brad point bits get used in drilling small and clean holes. The point drills into the wood first and prevents the drill from slipping, while the edges prevent the middle from splintering the wood by first cutting in, creating a clean hole, thereby.

#3. Metal Bits

Metal Bits

For drilling into metal, you'll be best served with an HSS (High-Speed Steel) bit coated with cobalt. There are also step bits and titanium-coated steel bits.

High-Speed Steel gets manufactured by combining carbon steel with other elements like vanadium and chrome to produce a very strong steel that can withstand high temperatures, and hence the name High-Speed Steel because high temperatures arise during high-speed drills.

You can use an HSS bit to drill wood and plastic materials, but keep in mind that the opposite is not advisable. That is, you can't drill metal with a wood bit because you'll definitely damage something.

#4. Glass & Tile Bits

Glass & Tile Bits

You can identify these bits by their spear-shaped heads, which have earned them the name “spearhead bits”. They are usually made from tungsten carbide and suitable for drilling both glass and tiles.

Always use them at low speeds and apply water to the glass if possible. It's also better to keep the glass on a flat and soft surface for support.

#5. Specialty Bits

Specialty Bits

In addition to the above four major types of bits, you'll also find a host of specialty bits, which usually come with a single purpose. Such bits include the Forstner bit for drilling shallow holes in wood and the hole saw for drilling wider holes in wood.

Another interesting bit is the step bit. This bit gets used on wood, plastic, and soft metals. It comes with lots of steps in a stair-like way, which also correspond to how wide you want to make the hole. You simply push down on your drill to widen a hole with the next and larger step.

How to Buy the Best Drill Bits

How to Buy the Best Drill Bits

You can see how varied drill bits are and that your choice of a bit depends on what you plan to do with it. You should also know by now that the wrong bit choice can cause you a lot of problems.

In order to choose the best drill bits, therefore, you'll need to focus on the following important aspects:

#1. Your Main Purpose

Believe it or not, your main purpose for buying a drill bit will help you to figure out to a large extent, the exact type of bit you need to buy. This refers to whether you're working on wood, metal, or masonry.

In addition to knowing the best kind of tip and flute to get, you may also need to get a stronger drill or to get a bit with non-standard shank for maximum power delivery, especially when working with masonry.

#2. Drill Bit Material

A good knowledge of drill bit materials and their characteristics is important when working with drills because it enables you to work with maximum efficiency. Following are the most popular drill bit materials and their best uses:

  • Steel Bits. Steel bits are generally used on softwood. The advantage of using steel bits is their low price, while their disadvantage is that they'll quickly go dull or even break when used on harder materials like hardwood.
  • High-Speed Steel Bits. HSS bits are slightly tougher than normal steel bits, so they stay sharp longer. In addition, they're also more resistant to heat than normal steel, so they are usually used on a variety of materials including metals.
  • Black Oxide Bits. HSS bits coated with black oxide get used on all kinds of materials, including hardwood and metals. The black oxide coating is inexpensive, heat-resistant, and it protects the steel and makes it last longer than normal HSS bits.
  • Titanium Bits. These are HSS bits coated with titanium. They cost a little more than HSS bits, but they can stay sharper for up to 6 times longer.
  • Carbide-tipped Bits. These stay sharp longer than steel, HSS and titanium bits. They also cost a little more. Their strength makes them ideal for drilling masonry.
  • Cobalt Bits. The main feature of cobalt bits is their exceptional heat resistance and toughness. This makes them the go-to bits when you need to drill through extremely strong materials like cast iron, stainless steel, and others.

#3. Drill Bit Shank

A shank is the part of a drill bit that goes into your drill's chuck. There are three major types of shanks and they each have their advantages and disadvantages.

The round shank is good because it provides more accuracy, while the hex shank is good because it enables the drill chuck to grip it more tightly and deliver more torque.

The third type of shanks is the SDS shank. This comes designed for use with hammer drills. It does not need tightening but can deliver maximum thrust for better efficiency.

#4. Size of Set

You probably will be needing your drill bit from time to time, so it pays to think a bit about the future. Many manufacturers offer different quantities of the same bits as a set. Consider buying a larger set, which will give you more options down the line.

#5. Quality & Warranty

You'll find everything from a short 30-day guarantee to a lifetime warranty, depending on the manufacturer. Longer warranties are often given for higher quality products, which also cost more, as a result.

Although any set of bits with a longer warranty gets more points for being more valuable, the final choice remains yours, on how much extra you're willing to pay for quality and manufacturer warranty.

Conclusion

We've come to the end of this drill bit review and you've seen the different drill bit sets available and their different prices as well.

So, whether you're in search of a top drill bit or a low-cost budget option, you should know how important a drill bit's material is by now, so you don't have the wrong expectations.

In the end, though, the last choice is yours to make between a costly and long-lasting drill bit set and a cheaper one made from a lesser tough blend of steel.
