Best Drill Index Set: Top Picks For Every Job
The best drill index set should offer strong bits, useful sizes, clean cuts, and easy storage.
Picture a busy Saturday in a U.S. garage. You need to drill a hole in a steel bracket, then switch to wood for a shelf project. Your old bit gets hot, slips, or leaves a rough hole. You reach for another bit, but the right size is missing. A good drill index set can solve that problem fast. It gives you many sizes in one case. It also makes it easy to keep your bits sorted and ready. In this guide, I compare five sets that cover home repairs, shop work, metal jobs, wood projects, and general use.

MACXCOIP 115Pcs Cobalt Drill Bit Set M35 HSS
I like this set for users who want a wide range of cobalt bits in one large kit.
DEWALT 21 Pc Titanium Nitride Drill Bit Set
This compact set is a strong choice for common home, wood, plastic, and light metal jobs.
MACXCOIP 29Pcs M35 Cobalt Drill Bit Set
It offers a practical size range and cobalt construction without the bulk of a very large kit.
MACXCOIP 115-Piece M35 Cobalt Drill Bit Set
The MACXCOIP 115-piece set is the largest kit in this group. It uses M35 cobalt high-speed steel, which makes it a useful pick for many metal drilling tasks. The large count gives me more size choices than a small home kit. That can help when I work on mixed jobs and do not want to stop and buy another bit.
This set also makes sense for a busy garage or small shop. The jobber-length design works well for many normal drilling tasks. Cobalt bits can handle heat better than basic high-speed steel, but I still use the right speed and cutting fluid when drilling hard metal. For shoppers who want the best drill index set with a wide size range, this kit is worth a close look.
✅ Pros
- ✔ Large 115-piece selection gives you many size choices.
- ✔ M35 cobalt HSS construction suits many metal drilling jobs.
- ✔ Useful for stainless steel and other hard metal work when used with proper technique.
- ✔ Jobber length fits many common drill tasks.
- ✔ One large kit can reduce the need to buy extra bits.
- ✔ Good choice for users who handle many different projects.
- ✔ A broad selection helps with repair work and shop tasks.
⚠️ Cons
- ✖ A large kit takes more storage space than a small index.
- ✖ More pieces can make it harder to find one exact size at a glance.
- ✖ Cobalt bits still need care and correct drill speed for long life.
My Recommendation
I would choose this set for a serious DIY user, repair worker, or small shop that wants many drill sizes in one case. The main draw is range. You get far more size choices than with a basic 21-piece kit. If your work often changes from one metal size to another, that range can save time. I would not buy a large set just for a few simple home projects. In that case, a smaller kit may be easier to store and use. For someone searching for the best drill index set with broad coverage, though, the 115-piece format is appealing.
| Best For | Why |
|---|---|
| Busy DIY users | The large range covers many repair and build tasks. |
| Metal work | M35 cobalt HSS is suited to many metal drilling jobs. |
| Small shops | One broad kit can cover many common bit sizes. |
M35 Cobalt 29-Piece Drill Bit Set
This 29-piece M35 cobalt drill bit set offers a simple middle ground. It covers sizes from 1/16 inch to 1/2 inch, so it fits many common U.S. shop and home projects. The bits use high-speed steel with cobalt content, which can be useful when drilling hard materials. The index case also helps keep the sizes in order.
I see this type of kit as a good fit for people who want more metal strength than a basic bit set can offer. It is smaller than the 115-piece option, so it takes less room on a workbench. It can work with metal, wood, plastic, and cast iron when the bit, speed, and feed match the job. For many users, this balance can make it a strong candidate for the best drill index set.
✅ Pros
- ✔ 29 common sizes provide solid coverage for many projects.
- ✔ 1/16-inch to 1/2-inch range covers many standard drilling needs.
- ✔ M35 cobalt HSS is a useful choice for hard metal work.
- ✔ The storage case keeps sizes organized.
- ✔ Smaller than a 100-plus-piece kit.
- ✔ Works across several material types when used correctly.
- ✔ A practical size range suits both DIY and shop work.
⚠️ Cons
- ✖ It has fewer pieces than the 115-piece set.
- ✖ Cobalt bits can cost more than simple HSS bits.
- ✖ The set may offer more metal performance than a casual user needs.
My Recommendation
I recommend this style of 29-piece kit for people who want a focused set rather than a huge box of bits. The 1/16-inch to 1/2-inch range is useful for many home repairs, garage jobs, and metal projects. I also like the case because it makes size selection quick. If you want one compact set for regular work, this is a sensible option. It may be especially useful for users who drill metal often but still need bits for wood and plastic. As a result, it deserves a place in a best drill index set comparison.
| Best For | Why |
|---|---|
| DIY repairs | The common size range handles many household jobs. |
| Metal projects | M35 cobalt HSS offers useful heat and wear resistance. |
| Compact storage | The 29-piece case is easier to store than a large kit. |
MACXCOIP 29-Piece M35 Cobalt Drill Set
This MACXCOIP 29-piece set is built around the same useful 1/16-inch to 1/2-inch size range many home and shop users need. Its M35 cobalt HSS design targets drilling work where a normal basic bit may not be enough. The jobber-length format also fits many standard drill tasks. I like this type of set because it keeps the selection focused instead of filling a case with sizes I may rarely use.
The case adds a simple but important benefit. A marked index makes it easier to return each bit to its place after a job. That helps prevent lost bits and saves time when I need a certain size. If you want the best drill index set for regular DIY work with an emphasis on metal, this compact MACXCOIP kit is a practical choice.

- ✔ M35 cobalt HSS supports many metal drilling tasks.

- ✔ Compact size makes storage easy.
- ✔ Useful for DIY, repair, and workshop jobs.
⚠️ Cons
- ✖ It does not offer the very wide selection of a 115-piece kit.
- ✖ Cobalt bits need careful use to avoid excess heat.
- ✖ Users who mainly drill wood may not need cobalt construction.
My Recommendation
I would consider this set when I want a compact kit that focuses on useful sizes. It gives enough range for many home repairs without the size of a large professional-style case. The cobalt HSS build also gives it a clear role in metal work. For a homeowner who drills metal now and then, this can be a good balance. It also suits a garage user who wants a dedicated index that stays easy to carry. Among the options here, it is a strong choice for buyers who value simple storage and a practical size range.
| Best For | Why |
|---|---|
| Homeowners | It offers useful sizes without a very large case. |

EASTPACE 29-Piece Cobalt Drill Bit Set
The EASTPACE 29-piece set combines a familiar size range with an M35-style cobalt HSS design. It covers 1/16 inch through 1/2 inch, which makes it useful for many common drilling tasks. The black and gold finish gives the bits a distinct look, while the twist design supports standard drilling work. The index case also keeps the set easy to sort and carry.
This set targets users who want one kit for more than one material. It is listed for work with cast iron, hard metal, stainless steel, plastic, and wood. I would still match the bit type and drill speed to the material instead of treating one bit as a universal tool. If you want the best drill index set for mixed home and garage use, this set offers a useful mix of size coverage and material range.
✅ Pros
- ✔ 29-piece set covers 1/16 inch to 1/2 inch.
- ✔ Cobalt HSS design fits many metal drilling tasks.
- ✔ Black and gold finish makes the set easy to recognize.
- ✔ Index case helps keep sizes organized.
- ✔ Can serve mixed-material DIY work.

⚠️ Cons
- ✖ It has fewer size choices than the 115-piece kit.
- ✖ The cobalt design may be more than needed for simple wood work.
- ✖ Hard metal drilling still requires good speed, pressure, and cooling.
My Recommendation
I would pick this set for a DIY user who wants one compact index for several material types. The size range covers many everyday needs, and the case keeps the bits easy to find. It can make sense for a garage where tools need to serve many roles. I would also consider it for a homeowner who does not want a huge set. When looking for the best drill index set, buyers should think about the jobs they do most often. This kit fits users who want broad material use in a small package.
| Best For | Why |
|---|---|
| Mixed-material DIY | The set is designed for several common material types. |
| Home garages | The compact case is easy to store and carry. |

DEWALT 21-Piece Titanium Drill Bit Set
The DEWALT DW1361 takes a different path from the cobalt kits in this guide. It has 21 drill bits with a titanium nitride coating and a pilot point design. That design can help the bit start with less walking, which is useful when I need a clean start on a workpiece. The set also targets common work in wood, metal, and plastic.
For a homeowner or general DIY user, this compact kit has a clear appeal. It does not try to provide dozens of extra pieces. Instead, it focuses on a smaller set for everyday drilling. If your search for the best drill index set is about home repairs, shelves, fixtures, and light workshop jobs, a compact DEWALT set can be easier to use than a large metal-focused kit.
✅ Pros
- ✔ 21-piece size selection keeps the kit compact.
- ✔ Titanium nitride coating is designed for durability in common drilling work.
- ✔ Pilot Point design helps the bit start with less wandering.
- ✔ Useful for wood, metal, and plastic.
- ✔ Compact case fits well in a home tool collection.
- ✔ A familiar brand makes it easy to add to an existing DEWALT setup.
- ✔ Good fit for common home and DIY drilling tasks.
⚠️ Cons
- ✖ It has fewer bits than the cobalt sets in this comparison.
- ✖ It is not the first choice for every demanding hard-metal task.
- ✖ Titanium coating does not mean the bits never need proper speed and care.
My Recommendation
I recommend the DEWALT set for people who want a simple kit for common home jobs. It is especially useful when I need to drill wood, plastic, and lighter metal without carrying a large index. The pilot point feature is also helpful when a clean start matters. If you mainly work with very hard metal, I would look more closely at the cobalt options. But if your goal is an easy general-purpose kit, this set can be one of the most practical choices in a best drill index set guide.
| Best For | Why |
|---|---|
| Homeowners | The compact selection fits many common repair jobs. |
| Wood projects | The pilot point design can help with clean starts. |
| General DIY | It supports common work in wood, metal, and plastic. |
Final Verdict: Which Should You Buy?
After comparing these five options, I would choose the MACXCOIP 115-piece M35 cobalt set when I want the widest range in one kit. Its large size selection makes it useful for varied shop and repair work. For a smaller kit, the 29-piece cobalt options give a better balance of size coverage and storage. For general home use, the DEWALT 21-piece titanium set offers a compact choice for wood, plastic, and many metal tasks. In the end, the best drill index set is the one that matches your materials, drill, project size, and most-used bit sizes.
