Bosch Pro SDS+ Chisel Bits
Breaking out mortar or lifting old tiles? A Bosch Professional SDS chisel turns hammer blows into controlled removal.
For fitters, builders and refurbishment teams, the right tip saves working the same patch twice. Match the shank to your machine, check it has hammer-only mode, then choose a point or flat chisel for the job.
What Are Bosch Professional SDS Chisels Used For?
- Break out small sections of concrete around redundant fixings with a point chisel, keeping the work within your hammer's rated capability.
- Remove mortar and loose masonry during refurbishment with a flat chisel, working in small sections to avoid damaging brickwork you need to keep.
- Lift old wall and floor tiles with a suitable tile chisel, approaching at a shallow angle to get beneath the tile rather than driving straight into the substrate.
- Trim local high spots and hardened mortar from masonry with a flat chisel before making good, without treating the tool as a replacement for proper surface grinding.
Choosing the Right Bosch Professional SDS Chisel
Buy for the shank and the material you need to remove first; a wider or longer chisel is not automatically a better one.
1. Match the Shank Before Anything Else
If your hammer takes SDS Plus, choose a Bosch Professional SDS Plus chisel. SDS Max is a different fitting and will not slot into an SDS Plus holder. Check that the machine also has hammer-only mode; an SDS chuck alone does not make a drill suitable for chiselling.
2. Choose the Working End for the Removal
Choose a Bosch Professional point chisel for concentrated breaking and starting a local break-out. Pick a Bosch Professional flat chisel for working along an edge or removing material in strips. For tile stripping, use a purpose-designed tile chisel where specified rather than forcing a narrow point underneath every tile.
3. Keep Width and Length Sensible
If you are using a compact SDS Plus hammer, do not expect a very wide blade to strip hard material quickly. Match the chisel to the machine's recommendations. Choose extra length only when access needs it, as a shorter suitable chisel is usually easier to control close to the work.
4. Buy a Set Only if You Need the Different Tips
A Bosch Professional SDS chisel set makes sense for mixed refurbishment work where you regularly switch between breaking and stripping. If you only replace worn flat chisels, buy the profile you actually use. Check the listed contents rather than assuming every set includes a tile chisel; find other task-specific options under Bosch Professional SDS Plus Other Bits and Accessories.
Who Uses Bosch Professional SDS Chisels?
Builders and refurbishment teams use these for local breaking and masonry removal without bringing in a separate breaker for every small job. Tilers reach for suitable tile chisels when stripping bathrooms and kitchens, while plumbers and sparkies use points and flats for controlled masonry removal around service alterations, after checking for concealed cables and pipes.
The Basics: Understanding SDS Chiselling
An SDS chisel removes material through repeated hammer blows, not rotation. The fitting holds the accessory while allowing the movement needed to transmit those blows into the work.
1. Hammer-Only Mode Does the Work
Set a compatible machine to hammer-only mode before chiselling. If it has a chisel-position adjustment, use that to set the blade angle, then return the selector to its working position as instructed. Do not run a chisel in rotary drilling mode.
2. The Fitting and Machine Must Both Be Suitable
Accessories in the Bosch Professional SDS Plus range share a fitting type, but drilling and chiselling place different demands on the machine. Check its permitted accessories and working modes, not just whether the shank fits.
Accessories for Masonry Preparation and Dust Control
Keep drilling accessories separate from chisels, and sort dust control before starting work indoors.
1. Masonry Drill Bits
If the job also needs fixing holes, use Bosch Professional SDS Plus Drill Bits rather than trying to form a fixing hole with a chisel. A drilled hole gives the specified diameter your anchor needs.
2. Drill Bit Sets for Mixed Fixings
For refits involving several fixing sizes after stripping out, Bosch Professional SDS Plus Drill Bit Sets keep the required diameters together. Check the included sizes against your fixings before heading to site.
3. Compatible Dust Extraction Attachments
Check Bosch Professional Dust Extractor Accessories for an attachment suitable for your machine and chiselling task. A drilling dust attachment is not automatically suitable for breaking work; pair the correct capture equipment with an appropriate extractor and the controls required by your dust assessment.
Choose the Right Bosch Professional SDS Chisel for the Job
Match the tip to the removal task, then confirm shank compatibility.
| Your Job | Chisel Type | Key Features |
|---|---|---|
| Starting a local break-out in masonry or concrete | Point chisel | Concentrated impact at the tip; suitable length for access and control. |
| Removing mortar or working along a masonry edge | Flat chisel | Cutting edge matched to the width of material being removed. |
| Stripping wall or floor tiles | Purpose-designed tile chisel | Blade profile suited to getting beneath tiles; check the stated application. |
| Handling several removal tasks during refurbs | Chisel set | Useful mix of profiles with the correct shank; verify the listed contents. |
Common Buying and Usage Mistakes
- Buying by the SDS name alone can leave you with the wrong fitting. Check SDS Plus or SDS Max on both the accessory and machine before ordering.
- Assuming every SDS drill can chisel leads to unsuitable tool use. The machine needs a manufacturer-approved hammer-only mode.
- Using the chisel as a lever can bend or break it and damage the tool holder. Break the material into smaller sections instead of levering out a large slab.
- Driving straight into tiles can gouge the backing and leave more making good. Use a suitable blade at a shallow working angle and take controlled passes.
- Starting without checking services or dust controls risks injury and harmful exposure. Locate concealed services and put suitable extraction, eye protection, hearing protection and any required RPE in place first.
Point Chisels vs Flat Chisels vs Tile Chisels
Point Chisels for Concentrated Breaking
A point concentrates the blow into a small area, making it useful for starting breaks in hard material. Choose it for local demolition, not for leaving an even stripped surface or lifting tiles cleanly.
Flat Chisels for Edges and Strips
A flat edge lets you work along mortar and masonry in controlled strips. It is a practical choice for general removal, but a wider blade needs enough impact from the machine to keep cutting effectively.
Tile Chisels for Getting Underneath
A purpose-designed tile chisel has a blade profile intended for stripping tiles from their backing. Choose it for repeated kitchen and bathroom strip-outs rather than using a point that tends to punch through the tile.
Maintenance and Care
Clean the Shank Before Fitting
Remove grit and masonry dust before inserting the chisel. Lubricate the shank only as directed by the machine manufacturer; dirty grease carries abrasive material into the holder.
Inspect the Tip and Fitting
Check for cracks, bending, chipped edges and damage to the shank grooves. Stop using a damaged chisel rather than forcing it through another job, and have a worn tool holder checked.
Follow Profile-Specific Sharpening Advice
Do not assume every chisel should be ground back to the same shape. Follow Bosch's guidance for the particular model, especially where it has a self-sharpening profile. Uncontrolled grinding can alter the profile and overheat the steel.
Store Dry and Let Hot Steel Cool
Let the chisel cool before handling or packing it away. Wipe off moisture and store it dry, with the working end protected from loose tools. Do not quench a hot chisel in water.

Bosch Professional SDS Chisel FAQs
What are SDS chisels used for?
SDS chisels are used with compatible machines in hammer-only mode to break and remove material. Typical jobs include local masonry break-outs, mortar removal and tile stripping. Choose a tip intended for the material and keep the task within the machine's capacity.
What is the difference between a point and flat chisel?
A point concentrates impact into a small area to start a break. A flat chisel spreads the blow along an edge, making it more useful for removing material in strips or working along masonry edges. Neither guarantees a clean finish; working angle and the condition of the substrate still matter.
Do Bosch SDS chisels fit any SDS drill?
No. The fitting must match: SDS Plus and SDS Max are not interchangeable. A Bosch SDS chisel can fit a compatible holder from another brand, but the machine must also permit chiselling and have hammer-only mode. Check both manuals before use.
Are Bosch sds chisels any good?
Bosch Professional offers chisels intended for trade breaking and removal tasks, but the right model matters more than the name alone. Match the profile to the material and check any model-specific wear or self-sharpening features. Even a suitable chisel will wear quickly if used for levering or forced beyond its intended application.
Where are Bosch tools made?
Bosch manufactures tools and accessories in several countries; they are not all made in Germany. Country of manufacture varies by product. Check the packaging or product markings for the exact chisel, or ask ITS to confirm the item details before ordering if origin is a purchasing requirement.
