Bosch Daredevil multipurpose bits fit different tools depending on the exact bit: cylindrical-shank models fit three-jaw drill chucks, while listed 1/4-inch hex-shank models fit tools that accept 1/4-inch hex bits. [1][2] Check the shank on your bit and the tool’s holder before you connect them; the product name alone does not tell you which interface you have.
That check helps you avoid buying a bit that will not fit your drill or driver. For example, the Bosch Daredevil 5/16-inch multipurpose bit listing says it works in corded and cordless tools that accept 1/4-inch hex-shank bits. [2] By contrast, Bosch describes the Daredevil multipurpose drill bit set’s shank as cylindrical and compatible with three-jaw drill chucks. [1] For more detail, see . Bosch Daredevil Multipurpose Drill Bit Materials: What They Drill.
The practical rule is simple: match the shank to the tool, then confirm the exact model before use. The distinctions below explain what to look for when comparing a chuck-style drill with a tool that takes hex bits.
Why do Daredevil bits have different shanks?
Bosch Daredevil bits can have different shanks because compatibility depends on the specific bit or set, so check the product’s own specifications before choosing a chuck or driver. Bosch describes its Daredevil Multipurpose Drill Bit Set as having a cylindrical shank compatible with three-jaw drill chucks. [1] A listing for the MP09 multipurpose bit, by contrast, says it works with tools that accept 1/4-inch hex-shank bits. [2] You may also find this useful: .

Match the shank to your tool
A cylindrical shank is the familiar round bit end that a three-jaw drill chuck grips. If you’re considering the set described by Bosch, that stated compatibility points to using a tool with a three-jaw chuck. [1] Check your drill’s chuck rather than assuming every Daredevil bit attaches the same way.
A hex shank has flat sides, and the MP09 listing identifies its shank size as 1/4 inch. [2] That listing says the bit is suitable for corded and cordless tools that accept 1/4-inch hex-shank bits. [2] For example, if your tool accepts that bit type, the MP09 listing describes it as compatible; if your tool has a different chuck or holder, verify fit before starting work.
Why the details matter
The product name alone may not tell you which shank a particular bit uses. The available evidence describes a cylindrical shank for the multipurpose set and a 1/4-inch hex shank for the MP09 listing, so don’t apply one description to every Daredevil multipurpose bit. [1][2]
Before buying or loading a bit, check its model number and the product page’s shank description, then compare that description with your drill or driver’s chuck or holder. If you’re comparing a set with an individual bit, confirm the specifications for each product rather than relying on a general label such as “multipurpose.” This simple check helps you avoid choosing a bit that won’t fit your tool; it also keeps the decision focused on the exact model you plan to use.
How can you match the shank to your tool?
Match the bit’s shank to the tool’s chuck or bit holder before you drill; the shape tells you which connection to check. Bosch describes its Daredevil multipurpose set’s cylindrical shank as compatible with three-jaw drill chucks. [1] A separate Daredevil bit listing says it can be used in corded or cordless tools that accept 1/4-inch hex-shank bits. [2]
Inspect the shank. Look at the end that goes into the tool, not the cutting tip. A cylindrical shank has a round profile; a hex shank has flat sides. For example, if the bit end looks like a straight round rod, check for a three-jaw chuck; if it has six flat faces, check the tool’s bit interface. The sources identify cylindrical and 1/4-inch hex shanks for the products described, but they do not establish that every Daredevil bit uses either type. [1] [2]
For a cylindrical shank, use a three-jaw chuck. Bosch specifies that chuck type for the cylindrical shank on its Daredevil multipurpose set. [1] Open the chuck, seat the shank, then tighten it according to the tool’s instructions. If your tool has only a hex bit holder, don’t assume a round-shank bit will fit securely; check the exact tool and bit instructions instead.
For a 1/4-inch hex shank, check the tool’s interface. The cited listing says the bit works with corded and cordless tools that accept 1/4-inch hex-shank bits. [2] That does not mean every drill or driver accepts this interface. Check the tool’s manual or product specifications for the bit-holder size and type; a matching-looking opening is not enough to confirm compatibility.
Verify the exact model if the marking is unclear. Compare the bit’s model number and shank description with the manufacturer’s specifications. Product descriptions can cover a particular set or bit, so use the listing for the exact model you own rather than extending one listing’s details to the whole Daredevil line. If the bit and tool descriptions still do not match clearly, pause and confirm with the manufacturer before use.
What about impact drivers and hammer drills?
Hex-shank Bosch Daredevil multipurpose bits may fit impact drivers and hammer drill/drivers, but check the exact bit’s packaging or Bosch product page before using one that way. Some listings describe compatible bits as impact-rated, while another source reports a warning against impact-driver use on a particular package. [3][4][5][6]
Impact drivers
A listing for the MP500T five-piece set says its hex-shank bits are intended for impact drivers and hammer drill/drivers. [3] A separate listing also describes hex shanks and an impact rating for use in those tools. [4] A review likewise says the impact-rated hex shank works with hammer drills and impact drivers. [5]
That does not establish that every Daredevil multipurpose bit has the same rating or tool-use limits. A forum post reports that the fine print on a package said not to use the bits with an impact driver. [6] Treat that as a reason to check the instructions for the exact bit, not as a universal rule for the product line.
For example, if you have a hex-shank bit and an impact driver, confirm that the packaging explicitly allows impact-driver use before fitting it. If the package says not to use it in an impact driver, follow that restriction and choose a bit approved for the tool instead. The available sources do not establish that a hex shank alone means a bit is impact-rated.
Hammer drills
Some listings describe the bits as suitable for hammer drill/drivers. [3][4][5] Check whether the packaging refers to a hammer drill/driver and whether it permits hammer mode; the available source excerpts do not spell out mode-specific limits for every bit. If the instructions are unclear, use the bit in the mode expressly allowed by the manufacturer rather than assuming that a hammer-drill fit means every operating mode is approved.
Before drilling, match the bit’s shank to the tool’s chuck and confirm the manufacturer’s use limits. The practical takeaway is simple: rely on the exact bit’s packaging or manufacturer information, not a broad claim about the Daredevil name or hex-shank shape.
What should you check before drilling?
Before drilling, match the exact Bosch Daredevil bit’s shank to your tool’s chuck or holder, then check the manufacturer’s instructions if anything is unclear. The product details in the sources describe a cylindrical shank for the Daredevil Multipurpose Drill Bit Set, while a separate 5/16-inch bit listing says that bit is for tools that accept 1/4-inch hex-shank bits.[1][2] Those details show why you should check the specific bit rather than assume every bit in the range has the same shank.
Check the package or listing
Start with the bit’s model number and the shank description printed on its package or shown in its product listing. For example, the Daredevil set listing identifies a cylindrical shank and says it is compatible with three-jaw drill chucks.[1] A separate listing for a 5/16-inch Daredevil bit describes a 1/4-inch hex shank.[2] Treat those as product-specific details, not as interchangeable descriptions.
If you are comparing bits, write down the model number and shank type before you shop. That gives you a direct way to compare the package with your tool’s instructions or product details. Don’t rely only on the bit’s diameter or the word “multipurpose”: neither tells you, by itself, what kind of chuck or holder accepts its shank.
Check the tool
Look at the tool’s chuck or holder and confirm that it accepts the shank type listed for your bit. Bosch describes the set’s cylindrical shank as compatible with three-jaw drill chucks.[1] The separate 5/16-inch bit listing specifies tools that accept 1/4-inch hex-shank bits.[2] If you have a different bit, use its own listing rather than applying either description automatically.
For instance, if you have a three-jaw chuck, compare its instructions with the bit’s stated shank type. If you are considering the listed 5/16-inch bit for another holder, check that the holder accepts a 1/4-inch hex shank before you start. If the product information does not clearly match your tool, pause and check the manufacturer’s instructions instead of guessing.
Confirm permitted use
Check the manufacturer’s instructions when the tool fit or the permitted use is uncertain. The source listings identify shank compatibility, but they do not establish that every tool, setup, or drilling task is suitable. Keep the package or product listing handy while you check, and compare the exact model and shank details with the tool documentation before drilling.
Common questions about Daredevil bit shanks
Check the exact Daredevil bit’s shank and approved use before you choose a holder or tool; the product line includes different shank options. Bosch lists a Daredevil multipurpose set with a cylindrical shank for three-jaw drill chucks, while another listing describes hex-shank bits. [1][3]
Does every Daredevil multipurpose bit have a hex shank?
No. Bosch lists a Daredevil multipurpose set with a cylindrical shank, and a separate listing describes hex-shank bits. [1][3] For example, if you are comparing a loose bit with a boxed set, check the specific model or packaging rather than assuming the shank is the same across the line.
Can a cylindrical shank go in a hex holder?
The available sources do not establish that a cylindrical-shank bit fits a hex holder. Bosch describes its cylindrical-shank set as compatible with three-jaw drill chucks. [1] Check the holder and bit specifications before buying or trying the combination; do not rely on the product-family name alone.
Does a hex shank mean the bit fits my tool?
Not by itself. One Daredevil bit listing says it is for tools that accept 1/4-inch hex-shank bits. [2] Compare that stated shank size with your tool’s holder, and confirm that the exact bit is intended for your tool and task. A matching shape alone does not establish every kind of compatibility.
Does hex-shank fit confirm impact-driver use?
No. A product listing describes a particular set as allowing use in impact drivers and hammer drill/drivers, but that does not confirm approval for every Daredevil model. [3] Check the instructions or specifications for the exact bit before using it in an impact driver. Another source reproduces a warning against impact-driver use for unspecified Daredevil bits, so avoid applying that warning—or the opposite claim—to the whole product line. [6]
What should I check before buying?
Match the bit’s listed shank type and size to the tool holder, then check the exact model’s stated uses. For instance, a three-jaw chuck is the holder Bosch names for its listed cylindrical-shank set. [1] If the packaging or model details do not answer your question, confirm compatibility with the bit or tool manufacturer rather than guessing.
Check the exact bit before you use it
The safest check is to match the exact bit’s shank to the chuck or holder on your drill, then follow the instructions for that tool. Bosch describes the Daredevil Multipurpose Drill Bit Set as having a cylindrical shank for three-jaw drill chucks. [1] A separate listing for the 5/16-inch Daredevil bit says it works with corded and cordless tools that accept 1/4-inch hex-shank bits. [2] Those descriptions point to different shank styles, so don’t assume that every Daredevil multipurpose bit fits the same holder.
Before fitting a bit, check its packaging or product listing for the exact model and shank description. Then compare that shape with your drill: a cylindrical shank is intended for a three-jaw chuck, while the cited 5/16-inch bit listing specifies a 1/4-inch hex-shank holder. [1][2] If your tool’s holder does not match the bit’s stated shank, choose a compatible bit rather than forcing it into place.
For example, if you have a drill with a three-jaw chuck, look for the cylindrical-shank description on the exact bit or set you plan to use. [1] If you have a tool that accepts 1/4-inch hex-shank bits, check that the particular bit is identified as a 1/4-inch hex-shank model before installing it. [2] The product name alone is not enough to confirm the fit; use the model-specific listing or packaging to verify the shank.
Once the shank matches, check the instructions for your particular tool for any additional use limits. Don’t infer operating guidance from another drill or from a different Daredevil bit listing; the available product descriptions establish shank compatibility, not every tool-use condition. If you cannot confirm the model or holder match, pause and check the manufacturer’s documentation before drilling.
Remember: match the exact bit’s shank to the tool’s chuck or holder. Check the bit’s model-specific packaging or product listing, then consult your tool’s instructions for any additional limits before you start.
