Best Drill Bits for Wood

Milwaukee Shockwave Titanium Drill Bits

Milwaukee Shockwave Titanium drill bits are our choice for the best drill bits for wood. The 1/4″ hex shaft makes them suitable for use in both drills and impact drivers. Milwaukee uses what they call Red Helix variable-width flutes to eject chips better than standard designs. They also go with a 135° tip to help cut in more quickly and reduce bit-walking on metal.

Also the Best Titanium Drill Bits

Now, just because we dedicated these for our wood-drilling pick doesn’t mean they can’t drill through metal. The titanium coating is great for thinner steels and non-hardened metals. They also have excellent chip ejection and don’t heat up as quickly as other bits we’ve used.

These bits run around $104.99 for a 29-piece kit.

Drill America D/A29J-CO-PC 29-pc Cobalt Set

best drill bits for hardened steel Drill America

Drill America produces M42 cobalt bits with a reputation for durability in various materials. During extensive tests across numerous metals, we chose their jobber bits as the top choice for drilling through hardened steel.

These bits boast a 135° split point design, ensuring consistent and efficient drilling. The jobber length bits are ideal for handheld drills during field operations. They adhere to the National Aerospace Standard 907 and drill as much as 30% more quickly than traditional M2 high-speed steel bits. Additionally, Drill America retains the full diameter on its larger bits. That gives you additional stability, though this requires a 1/2-inch chuck for operation.

Ideal for drilling through hard, high-tensile materials like stainless steel or titanium, we selected the D/A29J-CO-PC set. This collection includes 29 bits housed in a durable plastic case. The circular design of the case facilitates easy selection of the desired bit.

Best Drill Bits for the Money

Ryobi Black Oxide Drill Bits

Best Drill Bits Buying Guide

Whether you’re in a pinch or just need to replace a set, Ryobi’s Black Oxide Drill Bits are just $21 for a set with 25 pieces that cover 1/16″ to 3/8″. Their 135° split point tips help reduce walking at the start of your hole. If you avoid thick or hardened metals, these are the best drill bits for the money. You can get better bits, but we like this for Pros and DIYers on a budget.

Pick these up for $21

Best Drill Bits for Concrete (Non-SDS)

Bosch Daredevil Multi-Purpose Drill Bits

Best Cordless Drill

SDS-Plus and SDS-Max rotary hammers do best for drilling on concrete and masonry materials. Hammer drills, however, more than suffice for drilling smaller diameter holes. When you start looking for the best concrete drill bits and the best masonry drill bits, the need for handling multiple materials arises. For that, our Pros consistently turn to Bosch Daredevil Multi-Purpose Drill Bits.

Just like SDS-plus and SDS-max bits, these use tungsten carbide cutting tips. The carbide tips on the Daredevil Multi-Purpose Drill Bits are tough enough to cut through almost any material. We use these when drilling through combinations of wood, metal, tile, composites, and—of course—concrete. We also frequently pop them into impact drivers to quickly get through various materials.

These bits run considerably more than black oxide, titanium, or even cobalt bits on average. The cost may leave you buying just the specific sizes you need as needed—and that makes sense. However, the 5-piece set covers the most common sizes you may need without turning to a rotary hammer.

Grab the 5-piece set for just $22.99.

Best Drill Bits for Brick and Cinder Block (only)

DeWalt Percussion Masonry Drill Bit Set

Best Drill Bits for Brick and Cinder Block

When you know you need to drill into brick and cinderblock alone, having a dedicated set of bits makes sense. In this case, we feel one of the best drill bits for brick comes under the DeWalt brand. Mostly, we feel they simply hold up well for the price. You can pay more—and possibly get longer life, but if you bill your accessories to the job—these get the work done.

When paired with a cordless hammer drill, the DeWalt 7-piece percussion masonry drill bit set gives you some key advantages. The set includes a 3/16-inch x 3 bit, a 1/4-inch x 4 bit, and five 6-inch bits from 1/2-inch down to two 1/4-inch bits. From Tapcons to anchors, these bits fill a much-needed gap.

Grab the 7-piece bit set for $22.99.

Best Drill Bit for Tile and Glass

Bosch 8-piece Glass and Tile Bit Set with Case (GT3000)

It takes a particular bit to get through tile and glass without shattering the workpiece. In our opinion, the best drill bit for tile (also the best drill bits for glass) can be found in the Bosch 8-piece glass and tile bit set.

These bits use a wedge-shaped high-quality carbide tip with a reinforced head. It holds the tip rock-solid in place when you start your hole. It also reduces stress to the material which prevents cracking. The diamond ground cutting edges deliver excellent durability.

Bosch uses a three-flat shank on bits 5/16 inches and larger. This keeps them from slipping in the drill. The kit includes 8 bits from 1/8-inch to 3/4-inch.

Grab the 8-piece kit for $49.99.

Best Spade Bits

Bosch Daredevil Spade Bits

Bosch Daredevil Spade Bit

In a recent head-to-head, the 2nd-generation Irwin Speedbor bits beat out the Bosch Daredevil spade bits in speed. So why don’t they appear at the top of our list? Simple. We love the self-feeding nature of these Daredevil spade bits. They drill more smoothly and require less effort.

A threaded tip and wave design give the Bosch Daredevil an advantage over most of its competition. It cuts more smoothly and leaves a relatively clean hole compared to other spade bits. As icing on the cake, it has a 1/4″ hex shank so it fits in your impact driver.

Bosch also makes these bits up to 1-1/2 inches. They come in stubby, standard, and extended lengths for delving deeper into the material.

You can get a 13-piece set for $27.99.

Best Auger Drill Bit

Bosch Daredevil High-Speed Auger Bits

When the best drill bit for the job is an auger bit, we look to Bosch and their Daredevil lineup. Among the standard auger bit benefits, you’ll find that Bosch looks specifically to enhance performance with cordless drills. They tend to keep you in high speed so you drill faster. The tips help improve both your runtime and durability.

Price is the name of the game here. Most Pros just pick the sizes they need. Bosch, however, has a 3-piece set that includes 5/8″, 3/4″, and 1″ bits for $41.99.

Best Step Bit

Irwin Unibit Cobalt Step Bits

Best Drill Bit Buying Guide

Our team reaches for an Irwin Unibit Cobalt Step Bit when thin metal drilling is on the menu. The cobalt blend gives the bit a much longer life – an important point considering these are very difficult to sharpen.

A Speedpoint tip gets the hole started quickly and helps reduce the amount of wandering your bit does. It seems like a small thing at first, but Irwin laser etches the measurements on the inside of the flute so they won’t wear off over time.

Pick up a 3-piece kit for $75

What are the Best Drill Bits Made of?

Black Oxide (Coating)

Black oxide is a coating over the steel drill bit to add corrosion resistance and reduce friction between the bit and the workpiece. It’s a good general-purpose design that’s suitable for wood, softer metal, plastics, and composites that don’t cost an arm and a leg. The downsides are that they don’t stay sharp as long as some of the other twist bit options out there and you lose the benefits as the coating wears off the cutting edges.

When these bits go dull, you toss them. Also, don’t expect to cut through metal other than softer steels under 1/8-inch in thickness.

Titanium (Coating)

Titanium nitride is a coating you can use instead of black oxide that does the same job of resisting corrosion and friction. The added benefit comes from increasing the surface hardness and creating a thermal barrier that reduces heat buildup. This type of drill bit lasts longer than black oxide.

Titanium drill bits tend to drill faster than black oxide and chips move through the flutes better. One of the downsides is that the titanium nitride is just a coating and you lose the benefits as the coating wears off the cutting edges. Another is that you’ll need to pay more for these.

Titanium is a good choice for metal and wood drilling. You’ll want to look elsewhere for concrete/masonry and you’re better off using your inexpensive black oxide bits for plastics and composites.

Cobalt (Steel Blend)

Cobalt drill bits are made from an alloy of 5% – 8% cobalt. Because the cobalt is part of the steel blend, its benefits run through the entire bit instead of wearing away like a coating. That characteristic also makes them an excellent candidate to sharpen rather than replace. With a much higher price tag than black oxide and titanium, you’ll want to go the sharpening route to save money.

Cobalt bits are capable of drilling through just about everything, though most Pros reserve them for metal drilling due to their cost. That’s a good move—you don’t want the one bit you own that’s able to drill through cast iron getting dull on everyday tasks that less expensive bits are perfectly capable of tackling.

Twist Bits

Twist bits work best for drilling in a myriad of materials when the target is a hole diameter of 1/2 inch or less. As you move beyond a 1/2″ hole diameter, you move away from traditional twist bits into some different options.

Spade Bits

One of the most cost-effective is a spade bit. Sometimes called a paddle bit thanks to its shape, spade bits throw chips out as they cut rather than sending it up through the flutes. It makes for a much cooler slow-motion video but generally leaves a larger mess. Unlike your standard twist bits, spade bits are only good for making holes in wood.

Auger Bits

Auger bits closely mirror spade bits but work better for deeper holes that require lots of chip removal at the point of entry. The full-fluted design makes this possible. It would help if you typically had a stronger drill when using these bits. This becomes very apparent when drilling deep holes or holes that exceed 3/4 inches in diameter.

Auger bits have a threaded tip that pulls the bit forward as it rotates in the wood. Its strong, full-fluted design also makes it easier to drill nice and straight.

Step Bits

Stepping away from wood and moving back into metal, you’ll find a need for step bits (AKA unibits). These are among the best drill bits for making holes in thin metal, like sheet metal or breaker boxes. A step bit starts with a short pilot, and then moves through a series of increasing widths as you move from one step to the next.

They’re great for moving beyond your standard twist bit sizes and eliminating the need for a punch for holes up to 1-1/4″ or a little more. They also feature a flat flute with a slight taper at each step. This gives you the ability to drill in sheet metal and other thin metals that might deform if you cut through at an angle. In addition to making new holes, they also excel at enlarging existing ones.

The downside is that you’re limited to around 1/8″ as your thickest material. These bits also cost more than other bits you likely own. Prices often exceed $50 for some sizes. Just keep in mind that each step bit you buy covers multiple hole sizes.
