DEWALT SDS+ DRILL BITS
Drilling fixing holes into brick or concrete? DeWalt SDS drill bits put a carbide cutting tip to work with your rotary hammer.
Sparkies, plumbers and fitters use them for clips, brackets and anchors. Match the shank to your machine, then check diameter and working length against the fixing specification. Choose the bit your job needs.
What Are DeWalt SDS Drill Bits Used For?
- Drill holes for cable clips and conduit saddles into sound masonry during first fix, matching the bit diameter to the specified wall plug.
- Make fixing holes for pipe brackets and sanitaryware supports in brick or concrete, checking the substrate and fixing requirements before drilling.
- Prepare concrete anchor holes for brackets and framework, using the specified drilling depth and cleaning procedure before installing the anchor.
- Drill through masonry walls for cable or small pipe routes, choosing enough working length to clear the wall without burying the flutes.
Choosing the Right DeWalt SDS Drill Bits
Check the chuck first, then buy to the fixing specification: the wrong shank will not fit, and the wrong hole can compromise the fixing.
1. SDS Plus or SDS Max
If your rotary hammer has an SDS Plus chuck, choose DeWalt SDS Plus masonry drill bits. SDS Max uses a larger, different shank for heavier machines. The systems are not interchangeable, so check the machine rather than guessing from the bit diameter.
2. Diameter and Working Length
For plugs and anchors, use the diameter and hole depth specified by the fixing manufacturer. Check working length separately from overall length: part of the bit sits in the chuck and cannot contribute to drilling depth.
3. Cutting Head and Substrate
For routine brick and concrete fixing holes, choose a bit rated for that material. Where available, a four-cutter head can help maintain a round hole and reduce snagging around reinforcement, but it is not permission to drill through structural steel. Stop and investigate unexpected metal.
4. Singles or Sets
If you fit the same anchors every day, buy replacement bits in those exact sizes and keep a spare. Choose a set for mixed maintenance work, but check its contents before assuming it covers your usual diameters and depths.
Who Uses DeWalt SDS Drill Bits?
Sparkies and plumbers keep DeWalt SDS Plus drill bits in their cases for repeated fixing holes in masonry. Maintenance teams use them for replacement brackets and equipment mounts, while installers drilling concrete anchors need the correct diameter and usable drilling length, not just a bit that looks close.
The Basics: Understanding SDS Drill Bits
SDS bits work with a rotary hammer rather than relying on a conventional chuck gripping a smooth shank. The connection lets the machine deliver hammer blows while turning the cutting head.
1. A Shank That Can Move
Grooves in the shank locate and retain the bit while allowing controlled movement along its length. This lets hammer energy reach the cutting tip. Use the matching SDS chuck system; tightening an SDS shank in a normal three-jaw chuck does not reproduce that action.
2. Cutting Tips and Dust Clearance
The carbide tip breaks the masonry while the flutes carry debris back out of the hole. Excessive pressure and packed flutes slow progress and build heat. Let the machine work and clear deeper holes as directed by the bit manufacturer.
Accessories for Cleaner, Consistent SDS Drilling
Control dust and clean fixing holes properly rather than leaving both jobs until the anchor is ready to go in.
1. Compatible Dust Extraction Attachment
A suitable drill-mounted extractor or extraction shroud captures dust at the hole instead of spreading it around an occupied room. Check compatibility with your machine, bit diameter and drilling depth, and connect it to suitable extraction where required.
2. Anchor Hole Cleaning Equipment
Correctly sized hole brushes and the specified air pump or vacuum equipment remove debris that can compromise anchor performance. Follow the fixing manufacturer's cleaning sequence; collecting dust at the surface does not necessarily leave the hole ready for an anchor.
Choose the Right DeWalt SDS Drill Bits for the Job
Match the shank, diameter and working length to the machine and fixing.
| Your Job | Bit Selection | Key Features |
|---|---|---|
| Fitting cable clips and pipe brackets | SDS Plus masonry bit in the specified plug size | Correct diameter and sufficient working length for the fixing depth |
| Installing concrete anchors | Concrete-rated SDS bit matched to the anchor specification | Specified hole diameter, depth and suitable cutting-head condition |
| Drilling through a masonry wall | Long-series bit compatible with your rotary hammer | Working length beyond the wall thickness and adequate debris clearance |
| Handling mixed maintenance call-outs | SDS Plus drill bit set | A useful spread of fixing diameters, with lengths checked before buying |
Common Buying and Usage Mistakes
- Buying SDS Max bits for an SDS Plus machine leaves you with kit that will not fit. Check the chuck designation before ordering.
- Using overall length as drilling depth can leave you short halfway through a wall. Buy against the stated working length.
- Forcing a blunt bit makes the drill work harder and can produce poor fixing holes. Inspect the carbide head and replace worn or damaged bits.
- Using hammer action on fragile brick or hollow masonry can break out the material around the hole. Follow the fixing and substrate guidance; rotary-only drilling may be required.
- Drilling without checking for concealed services risks hitting cables or pipes. Check plans, scan the area with suitable detection equipment and follow safe drilling procedures.
SDS Plus vs SDS Max vs Straight-Shank Masonry Bits
SDS Plus for Routine Fixing Holes
SDS Plus suits the lighter rotary hammers commonly used for clips, brackets and everyday anchor holes. It is a practical choice for repeated overhead drilling, but bit diameter and length must stay within the machine's rated capacity.
SDS Max for Heavier Drilling
SDS Max works with larger rotary hammers for demanding concrete drilling and larger holes. The heavier machine is unnecessary for most small fixing holes, and its bits will not fit an SDS Plus chuck.
Straight-Shank Bits for Conventional Chucks
Straight-shank masonry bits fit suitable three-jaw chucks and cover occasional masonry drilling with a compatible drill. For repeated holes in hard concrete, a rotary hammer and matching SDS bit are generally the more effective setup.
Maintenance and Care
Clean Before Storage
Remove loose masonry debris from the flutes and wipe the shank before putting the bit away. Use suitable dust-control methods rather than blowing fine concrete dust around the work area.
Look After the Shank
Keep the locating grooves free of grit. Apply the specified shank grease only as directed by the drill manufacturer; excess grease attracts debris and makes a mess of the chuck.
Check the Cutting Head
Inspect for chipped carbide, loose tips and uneven wear. Replace damaged bits, particularly when drilling specified anchor holes where an inaccurate diameter can affect the fixing.
Store Dry and Supported
Dry bits before storing them in a case or rack. Keep long bits supported rather than loose under heavy tools, and take bent bits out of service.

DeWalt SDS Drill Bit FAQs
What are SDS drill bits used for?
SDS drill bits make holes in materials such as concrete, brick and masonry using a compatible rotary hammer. Typical jobs include drilling for wall plugs, concrete anchors, pipe brackets and cable routes. Check the individual bit's material rating and follow the fixing manufacturer's drilling instructions.
What is the difference between SDS plus and SDS max drill bits?
SDS Plus has a nominal 10mm shank and is commonly used in lighter rotary hammers. SDS Max has a nominal 18mm shank with a different groove arrangement and fits heavier machines. They are separate chuck systems, not interchangeable sizes of the same fitting. Check your drill's specification before buying.
Can SDS drill bits be used in a normal drill?
They are not designed for a normal three-jaw chuck. The SDS shank needs a matching chuck that retains it while allowing the movement required for rotary-hammer operation. For a conventional drill, buy a suitable straight-shank masonry bit rather than trying to clamp an SDS bit in place.
Are DeWalt sds drill bits any good?
DeWalt SDS masonry bits are a practical option for trade fixing work when the bit is rated for the material and matched to the drill. Compare the particular range's cutting-head design and working length rather than buying on the name alone. Service life depends on the concrete, drilling technique and encounters with reinforcement; no bit is immune to damage.
Where are DeWalt tools made?
DeWalt manufactures across several countries, and the country of origin varies by product. A drill's manufacturing location does not establish where its accessories were made. For a particular SDS bit or set, check the packaging or product marking, or ask ITS to confirm the origin of the specific stock item before ordering.
