Burrs
Burrs are for the jobs where a disc is too crude tight fettling, cleaning out welds, shaping edges, and stripping back awkward spots in metal or masonry.
When you need to work into corners, dress back a rough edge, or clean up detail a standard disc cannot reach, burrs earn their place fast. These angle grinder accessories suit fabricators, fixers, installers, and maintenance teams who need controlled stock removal without making a mess of the job. If you already use Power Tool Accessories on site, adding the right burrs saves time on snagging, prep, and awkward rework. Pick the right shape and grit for the material, then get stocked up properly.
What Are Burrs Used For?
- Cleaning up welded joints on steel brackets, frames, and fabricated sections where you need to remove high spots without flattening the whole face.
- Shaping cut edges on pipe, box section, and plate after rough cutting, so fixings fit properly and nobody is left handling sharp burrs on site.
- Working into corners, recesses, and awkward details where larger angle grinder discs cannot reach cleanly or safely.
- Stripping back rust, old filler, or stubborn build-up on gates, handrails, and site metalwork before repainting, welding, or refitting.
- Trimming and dressing certain masonry or hard material details where controlled removal matters more than fast, rough cutting.
Choosing the Right Burrs
Sorting the right burrs is simple: match the burr to the material, the access, and how much you actually need to remove.
1. Match the Material First
If you are mostly dressing steel, deburring cut metal, or cleaning welds, go for burrs built for metal cutting accessories and grinding accessories use. If you are touching masonry or mineral-based material, use the right type for that job instead of forcing a metal burr to do work it is not meant for.
2. Pick the Shape for Access
If you are working flat edges, broader contact shapes make life easier. If you are getting into corners, holes, recesses, or around weld toes, choose a pointed or narrower profile. Wrong shape means slower work and a rougher finish.
3. Do Not Oversize It
If the job is fine cleanup on smaller parts, a compact burr gives you more control. If you jump straight to a larger size, it is easier to take too much off, mark surrounding material, or struggle in tight access.
4. Think About the Finish You Need
If you are removing a lot quickly, a more aggressive burr is the right call. If the part needs to be neat enough for fitting, painting, or visible finish work, back off and choose one that leaves a tidier result with less cleanup after.
Who Uses These on Site?
- Metalworkers and fabricators use burrs for dressing welds, cleaning edges, and fettling brackets so parts fit first time instead of needing a second trip back to the bench.
- Steel erectors and site fitters keep them handy for opening out awkward spots, knocking back proud metal, and sorting small fixes during install.
- Maintenance teams reach for burrs when gates, hinges, guards, and worn metal parts need tidying up without dragging out bigger kit.
- Plumbers and pipe fitters use them for deburring and shaping cut metal where a clean edge matters for fit-up and safe handling.
- General builders and refurb teams use them for snagging work, especially where detail cleanup is quicker than replacing a part or recutting the whole section.
Burr Accessories That Keep the Job Moving
A few sensible extras save wasted burrs, rough finishes, and extra trips back to the van.
1. Grinding Discs
Use Grinding Discs for the heavy stock removal first, then switch to burrs for detail work. It stops you burning through small accessories doing a big grinder's job.
2. Cutting Discs
Keep Cutting Discs nearby for rough cuts before cleanup. That way the burr is only refining the edge, not wasting time trying to remove bulk material.
3. Diamond Blades
If your work crosses into block, brick, or stone, Diamond Blades handle the actual cut properly. Save burrs for shaping, tidying, and awkward detail work afterwards.
Choose the Right Burrs for the Job
Use this as a quick guide before you buy burrs for site work.
| Your Job | Category or Type | Key Features |
|---|---|---|
| Dressing back welds on brackets and frames | Metal burrs for controlled stock removal | Good access to weld toes, steady material removal, better control than broad discs |
| Cleaning sharp edges after cutting pipe or box section | Smaller deburring burrs | More control on narrow edges, cleaner finish, less risk of gouging the workpiece |
| Working into corners and recesses | Narrow or pointed profile burrs | Gets where angle grinder discs cannot, useful on detail work and awkward access |
| General snagging and site rework | Mixed burr selection | Covers edge cleanup, shaping, weld dressing, and small correction jobs without changing approach |
| Light dressing on masonry details | Material-specific burrs for masonry cutting accessories work | Controlled trimming on hard materials, better for detail than rough cutting tools |
Common Buying and Usage Mistakes
- Buying one burr for every material is a common mistake. Metal and masonry do not behave the same, so use the right type or you will get poor cutting, fast wear, and a rough finish.
- Choosing a burr that is too large for the detail work usually ends with marked faces and too much material removed. If access is tight, size down and keep control.
- Using burrs for heavy bulk removal wastes time and chews through accessories. Rough the job out with the proper cutting or grinding accessory first, then use the burr for the accurate part.
- Ignoring the finish needed at the end of the job causes extra snagging later. If the part is visible or needs a close fit, choose a burr that leaves a cleaner result instead of the most aggressive one on the shelf.
- Running on with a worn burr gives slower work and more heat for less result. Once it stops cutting cleanly, replace it rather than forcing it and risking damage to the job.
Burrs vs Cutting Discs vs Grinding Discs
Burrs
Best when you need control, access, and detail. Burrs are for shaping, deburring, dressing welds, and sorting awkward spots where bigger angle grinder accessories are too blunt or too large.
Cutting Discs
These are for getting through the material fast, not for finesse. Use them to make the cut, then switch to burrs when the edge needs tidying or the fit needs refining.
Grinding Discs
Grinding discs remove stock quickly across wider areas and are better for flattening back heavy welds or rough surfaces. They are not the right answer for corners, recesses, or careful cleanup.
Which One Should You Buy
If the job is cutting, buy cutting discs. If it is flattening and heavy cleanup, buy grinding discs. If it is shaping, detail fettling, and controlled removal, buy burrs. Most site users need more than one type in the van.
Maintenance and Care
Keep Them Clean After Dusty Work
Brush off metal filings, masonry dust, and packed debris after use. If you leave them clogged up, they cut slower and run hotter next time out.
Store by Type and Size
Do not throw burrs loose in the bottom of the case with every other grinding accessory. Keep shapes and sizes separate so you can grab the right one quickly and avoid damaged cutting faces.
Check for Wear Before Starting
If a burr is badly worn, chipped, or no longer cutting evenly, bin it. Trying to squeeze one more job out of it usually costs more in lost time and poorer finish.
Use the Right Accessory for the First Pass
Burrs last longer when they are used for finishing and detail work, not rough removal. Start with the right disc or blade, then let the burr do the accurate bit it is made for.
Keep Them Dry in Storage
If they live in a damp van box, they will not thank you for it. Dry storage helps stop corrosion and keeps them ready for the next bit of site work.

Burrs FAQs
What are burrs used for?
Burrs are used for shaping, deburring, cleaning welds, dressing edges, and getting into awkward spots that standard angle grinder discs cannot reach properly. They are the right call when the job needs control rather than brute force.
How do I choose the right burrs?
Start with the material, then the shape, then the size. If you are working steel, buy a burr suited to metal. If access is tight, choose a narrower profile. If the work is fine and visible, do not go too aggressive or too large.
Which burrs are best for metal or masonry?
For metal, use burrs intended for dressing welds, cleaning cut edges, and controlled removal on steel and similar materials. For masonry, use the type built for hard mineral materials. Mixing them up is false economy and usually gives poor life and messy results.
How do I choose the right size burrs?
Choose the smallest size that still removes material efficiently. Smaller burrs give better control in tight spots and on finer work. Larger burrs suit broader access and faster removal, but they are easier to overdo if the job is delicate.
Can I buy burrs online from ITS?
Yes. You can buy burrs online from ITS with the range shown clearly by type and use, so it is easier to sort what you need for site work. Stock is held in our own warehouse for quick dispatch and next day delivery.
Are burrs enough on their own for most grinder jobs?
No, not usually. Burrs are the detail tool. Most trades will still need rough-cutting and grinding kit as well. For a proper setup, pair them with the right Cutting Discs, Diamond Blades, and Grinding Discs depending on the material.
