  • Drill bits are essential tools for both DIY enthusiasts and professionals, available in various sizes and types to suit different materials and tasks. A good drill bit set should be versatile enough to handle wood, metal, plastic, and even masonry, making it an invaluable addition to any toolbox. When selecting a drill bit set, consider the materials you’ll be working with most—some sets are specialized for wood and plastic, while others include bits for metal and concrete. The size of the set can also vary, with larger sets providing more options but potentially costing more. Quality is crucial, so look for bits made from durable materials like high-speed steel or carbide, and consider how the coating impacts performance and longevity. We tested numerous drill bit sets to identify the best options in terms of versatility, durability, and value.

    Pros

    • Titanium coating for longer life
    • Pilot point tips start on contact
    • Sturdy case keeps bits organized

    Cons

    • Pricier than basic sets
    • May be overkill for casual users
    • Some sizes have only one bit

    We’ve put this DEWALT set through its paces, and it’s clear why it’s so popular. The titanium nitride coating isn’t just for show – it really does help these bits last longer, even when drilling into tough materials. We found the pilot points made starting holes a breeze, with much less wandering than we’ve seen from other bits.

    The case is a standout feature. It’s tough enough to toss in a toolbox without worry, and the clear lid lets us quickly spot the bit we need. The bit-bar design is clever, making it easy to grab bits without dumping out the whole set.

    In use, these bits performed great on both wood and metal. They cut cleanly and didn’t overheat, even on longer jobs. The no-spin shanks lived up to their name, staying put in our drill chuck. While they’re not the cheapest option out there, we think the quality and durability make them worth the investment for anyone who does a lot of drilling.

    The 135-degree split points are a standout feature. They start drilling on contact without wandering, which is great for precision work. We found this especially helpful when working on metal surfaces where accuracy is key.

    The set’s range of sizes covers most common drilling needs. The clear case keeps everything organized and makes it easy to grab the right bit quickly. While it might be more than a casual DIYer needs, we think it’s a solid investment for anyone who does frequent drilling work.

    We think this premium drill bit set is worth the investment for serious DIYers and professionals who need reliable, long-lasting bits for metal work.

    Pros

    • High-quality steel for durability
    • Precise grinding for accuracy
    • Wide range of sizes

    Cons

    • Pricier than some alternatives
    • May be overkill for casual users
    • Gold oxide finish can wear off

    We’ve put these Norseman drill bits through their paces, and they really shine when working with metal. The 135-degree split point tips make starting holes a breeze, even on curved surfaces. We didn’t have to apply much pressure, which helped reduce fatigue during long jobs.

    The set includes 29 bits ranging from 1/16″ to 1/2″ in 64ths increments. This wide range came in handy for various projects. We especially liked the precision of these bits. They produced clean, accurate holes without wandering or creating oversized openings.

    During our tests, these bits held up well against wear. The high-molybdenum steel lived up to its reputation for toughness. While they’re not cheap, we think they offer good value for those who drill frequently or need reliable performance. For occasional home use, though, a less expensive set might suffice.

    We think this drill bit set offers great value for those who need to tackle a wide range of drilling tasks.

    Pros

    • Wide variety of bit sizes
    • M35 cobalt steel for durability
    • Efficient 135-degree tip design

    Cons

    • Flimsy storage case
    • May struggle with very hard metals
    • Some users report quick dulling

    We tested this 115-piece cobalt drill bit set from MACXCOIP and were impressed by its versatility. The set includes fractional, letter, and number sizes, covering most common drilling needs. We found the bits worked well on wood, plastic, and softer metals.

    The M35 cobalt steel construction gave these bits good staying power. We drilled multiple holes in aluminum and mild steel without noticeable dulling. The 135-degree split point tips helped prevent walking and made starting holes easier.

    While we liked the bits themselves, the storage case left something to be desired. It felt cheap and we worry it won’t hold up to regular use. We also had mixed results drilling very hard metals – some bits dulled faster than expected on stainless steel. For most DIY and light shop use though, this set offers a lot of options at a good price.

    The black and gold coating isn’t just for looks. It helped the bits resist rust and wear, even after repeated use. We liked the 3-flat shanks too. They gripped well in our drill chuck and didn’t spin out.

    One thing we noticed was the size markings on each bit. This made it quick to grab the right size without squinting or measuring. The set covers common sizes, but some users might want more options.

    While the case keeps things organized, we wish it was a bit tougher. Still, for most home users, it should do the job. These bits cost more than basic sets, but we think the quality makes them worth it for frequent use.

    We recently got our hands on the Amazon Basics 33-Piece Impact Bit Set, and we’re impressed with its versatility. The set includes 24 impact bits, 4 impact sockets, and 3 nut drivers, covering most common fastening needs. We found it handy for assembling furniture and tackling various household projects.

    The bits are made from S2 shock-resistant steel, which held up well during our tests. We appreciated the phosphate coating that adds extra protection against wear. The 6-point design on the sockets provided a secure grip on fasteners, even when we used them with our impact driver.

    One thing we really liked was the compact storage case. It kept everything organized and made it easy to grab the right bit quickly.

    We think this 29-piece cobalt drill bit set is a solid choice for DIYers and professionals who need to drill through tough materials.

    Pros

    • Wide range of sizes from 1/16″ to 1/2″
    • Cobalt steel construction for durability
    • Gold oxide finish reduces friction

    Cons

    • Pricier than basic HSS bit sets
    • Case could be more robust
    • May require frequent sharpening with heavy use

    We’ve put these Drill America bits through their paces, and they’ve impressed us with their performance. The cobalt steel construction really shines when drilling into harder metals. We found the 135-degree split points made starting holes a breeze, even without a center punch.

    The gold oxide finish isn’t just for looks. It helped the bits glide through materials with less friction, which meant less heat buildup. This is key for extending the life of the bits. We did notice that with very heavy use, they needed sharpening sooner than we’d like.

    While the plastic case keeps things organized, we wish it was a bit sturdier for job site use. Still, for the price, this set offers great value. It’s a step up from basic high-speed steel sets without breaking the bank. If you’re tackling tough drilling jobs, these bits are worth considering.

    We think this affordable drill bit set is a solid choice for DIY beginners and homeowners looking for a versatile collection of bits and accessories.

    Pros

    • Wide variety of bits and tools
    • Compact storage case
    • Good value for the price

    Cons

    • Not professional-grade quality
    • Some bits may wear out quickly

    We recently got our hands on the Amazon Basics 100-Piece Drill Set, and we were impressed by its range. The kit packs a lot into a compact case. It has drill bits for wood, metal, and masonry, plus screwdriver bits, hole saws, and more.

    For basic home projects, this set covers most needs. We drilled into drywall, wood, and even some thin metal with no issues. The bits aren’t top-tier quality, but they work well for common tasks. We like that the case keeps everything neat and easy to find.

    One thing to note is that all the drill bits are metric sizes. This might be a snag if you’re used to imperial measurements. Also, while the set is great for occasional use, pros or frequent DIYers may want tougher tools. Still, for the price, we think it’s a good starter set or backup kit for most homes.

    We recommend this drill bit set for its versatility and durability, making it a solid choice for DIY enthusiasts and professionals alike.

    Pros

    • Sharp, precision-ground bits
    • Wide range of sizes (1/16″ to 1/2″)
    • Durable cobalt steel construction

    Cons

    • Storage case can be tricky to use
    • Bits may dull quickly on harder materials
    • Some users report missing bits upon arrival

    We put this GMTOOLS 29-piece drill bit set through its paces on various materials. The bits proved sharp and effective right out of the box. We drilled through wood, plastic, and even some stainless steel with ease. The 135-degree split point helps prevent walking and makes starting holes a breeze.

    The black and gold oxide finish adds to the bits’ durability and corrosion resistance. We noticed less wear compared to standard HSS bits after repeated use. The set includes a good range of sizes, which came in handy for different projects around the workshop.

    One downside we found was the metal storage case. While it keeps the bits organized, it can be tough to remove bits if you have larger hands. We also noticed that the bits dulled somewhat quickly when drilling tougher materials like hardened steel. Despite these minor issues, we think this set offers good value for its price point and versatility.

Buying Guide

When shopping for a drill bit set, we recommend considering a few key factors:

Materials

Look for bits made of high-speed steel (HSS) for general use. For tougher jobs, cobalt or carbide-tipped bits offer better durability.

Bit Types

A good set should include:

  • Twist bits for wood and metal
  • Spade bits for woodworking
  • Masonry bits for concrete and brick

Size Range

Choose a set with a wide range of bit sizes to handle different tasks. Common ranges are 1/16 inch to 1/2 inch.

Case Quality

A sturdy case keeps bits organized and protected. Look for cases with secure bit holders.

Coating

Titanium or black oxide coatings can help bits last longer and resist heat.

Number of Pieces

More isn’t always better. We suggest focusing on quality over quantity. A 30-50 piece set is often enough for most users.

Intended Use

DIY users may not need professional-grade sets. Match the set to your typical projects.

TypesTwist, spade, and masonry bits
