Best Drill Bit Sets For 2024 (2024)

FAQs

What is the best drill driver bit set? ›

Carbide (Carb)

They are ideal for drilling through hard materials, including ceramics, glass, and masonry, as well as hard metals like stainless steel and cast iron. Advantages: This type is incredibly durable, can maintain its sharpness for longer than other drill bit materials, and can handle high-speed drilling.

M35 has excellent resistance to abrasion and very good red-hardness for working difficult materials. M42 “Super Cobalt” is American made premium cobalt material used for higher performance ITM cobalt drill bits. M42 has the best resistance to abrasion and red-hardness.

Number drill bit gauge sizes range from size 80 (the smallest) to size 1 (the largest) followed by letter gauge size A (the smallest) to size Z (the largest). Although the ASME B94. 11M twist drill standard, for example, lists sizes as small as size 97, sizes smaller than 80 are rarely encountered in practice.

Makita vs DeWalt summary

On the whole, if price and comfort is a big deal to you, then it'll be Makita. Whereas if you value power and warranty protection, then DeWalt is the right choice.

A twist bit is the most common type of drill bit for home use. It works for general-purpose drilling in wood, plastic and light metal.

Cobalt drill bits are often the best for drilling into hardened steel. Whereas titanium drill bits only have titanium in the coating, cobalt bits have cobalt throughout. After cobalt drill bits get worn out over time, you can resharpen them.

Carbide: The hardest and most brittle of the drill bit materials, it's used mostly for production drilling where a high-quality tool holder and equipment is used. It should not be used in hand drills or even drill presses.

Carbide is the strongest drill bit for metal and is typically reserved for professional-grade tools. Black Oxide is a coating added to HSS drill bits that helps reduce friction and speed up drilling through hard metals.

Cobalt drill bits make for optimal high-temperature applications and offer extreme durability. Cobalt drill bits can work longer without cutting fluids or cooldown periods, cutting through materials including cast iron, titanium, bronze, and stainless steel.

Which is better cobalt or HSS drill bits? ›

A Comparison: Cobalt or HSS? Cobalt is stronger than HSS, making it better for heavy duty drilling applications with a more rapid high-speed endurance. Cobalt also offers the advantage of being more heat resistant over standard HSS, allowing for longer running time performance when undertaking any drilling activity.

Cobalt bit

The addition of cobalt makes the drills more durable and that they can withstand higher temperatures during drilling without losing their edge. The disadvantage is that they're costlier, more brittle, and thus more likely to carve the leading edge.

As to the question “when should a cobalt drill bit be used," the answer is straightforward: anywhere you would use an HSS drill. Cobalt, however, will in most cases last longer than its less wear and heat-resistant cousin, and as we've seen, run much faster besides.

Both cobalt and titanium drill bits are used to make holes in hard, tough materials like metal. Cobalt drill bits are the toughest you can get, and have no coating, unlike titanium drill bits. Titanium bits are coated with titanium nitride or carbonitride to reduce the effects of heat.

For protection and portability, get a drill/driver kit that comes with a hard or soft carrying case. If you're shopping for a cordless drill, look for drill kits that include an extra battery. For added convenience, look for drill/driver kits with battery systems that work with different types of cordless tools.

Titanium drill bits are high-speed steel bits (HSS) that have a titanium black oxide coating. They are very hard, and corrosion-resistant. They last much longer than regular high-speed steel drill bits, and they are good for cutting through any metal, including sheet metal.

Titanium-coated HSS drill bits produce less friction. They're tougher than basic HSS bits and stay sharp longer. They work for drilling wood, metal, fiberglass and PVC. Carbide-tipped drill bits stay sharp much longer than steel, HSS or titanium bits.
