OX Tools Bolsters & Cold Chisels
OX bolster chisels are built for knocking out brick, trimming block and splitting masonry cleanly without wrecking your hands or wasting time on site.
When you're opening up blockwork, chasing out old mortar or tidying brick cuts, this is the sort of kit you reach for before the grinder comes out. OX bolster chisel, OX cold chisel and OX brick bolster options give you proper striking edges, solid shafts and, on selected models, handguards that save your knuckles on rough demolition jobs. Pick the width to suit the material and get the right chisel for the job.
What Are OX Bolster Chisels Used For?
- Splitting bricks and blocks on site is where an OX brick bolster earns its keep, especially when you need a quick clean break without dragging a saw across the plot.
- Chasing out damaged mortar joints or knocking off stubborn masonry high spots is easier with an OX cold chisel that can take repeated hammer blows without folding its edge straight away.
- Breaking back concrete edges, small patches of render or loose material around openings is a proper job for an OX concrete chisel when a full breaker would be overkill.
- Trimming blockwork around lintels, service runs and awkward reveals is exactly where an OX bolster with handguard helps, because you can keep striking without skinning your knuckles.
Choosing the Right OX Bolster Chisel
Sorting the right one is simple: match the edge width and pattern to the material in front of you, not just whatever is nearest in the van.
1. Bolster or Cold Chisel
If you are cutting across the face of brick or block, go for an OX bolster chisel or OX brick bolster with a wider blade. If you are chasing, chipping out or working into tighter areas, an OX cold chisel is usually the better shout because the narrower profile gets in where a bolster will not.
2. Pick the Right Width
If you are mainly trimming standard bricks and small blockwork, a narrower width gives you more control. If you are splitting broader masonry faces or want to move material faster, step up to a wider edge so you are not making extra hits for no reason.
3. Handguard or Plain Pattern
If the chisel is going to see plenty of lump hammer work, an OX bolster with handguard is worth having. It is not just a comfort thing. On fast demo and repetitive trimming, it saves your fingers from missed blows and glancing strikes.
4. Demolition or Cleaner Finishing Work
If you are knocking out rough openings or lifting old material, choose the tougher, heavier OX masonry chisel or OX concrete chisel style. For neater brick trimming and smaller corrective work, a brick bolster is easier to control and less likely to overbreak the edge.
Who Uses These on Site?
- Brickies keep an OX brick bolster in the bucket for cutting bricks, cleaning up block edges and making small adjustments that do not justify setting up a cutter.
- Groundworkers and demolition gangs use an OX masonry chisel for breaking back weak spots, lifting old sections and clearing loose concrete before repairs go in.
- Builders and general trades grab an OX bolster chisel for refurbs, knock-throughs and patching work where controlled hand demolition is safer than going straight in with power tools.
- Plasterers and maintenance teams use an OX cold chisel for chasing out damaged patches and removing blown material before they make good.
Accessories That Make Bolster Work Easier
A bolster is simple kit, but the right extras save your hands, your time and a lot of messy breakages.
1. Lump Hammers
Pair your OX bolster chisel with a proper lump hammer, not a tired claw hammer from the bottom of the bag. You will get cleaner strikes, better control and far less chance of battering the head or wasting hits.
2. Safety Glasses
Brick chips and concrete shards fly further than you think when you are striking hard. Decent eye protection stops a quick trimming job turning into a trip off site.
3. Work Gloves
Even with an OX bolster with handguard, gloves help when you are working all day in cold, dusty conditions. They give you grip on the shaft and take the sting out of repeated impact.
Choose the Right OX Bolster Chisel for the Job
Use this quick guide to avoid buying the wrong pattern for the work in front of you.
| Your Job | Category or Type | Key Features |
|---|---|---|
| Splitting facing bricks and small blocks | OX brick bolster | Wider cutting edge for straighter breaks and quicker trimming across the face. |
| Chasing out mortar and detail work | OX cold chisel | Narrower profile for controlled chipping in joints, corners and tighter sections. |
| Heavy striking on rough demolition | OX bolster with handguard | Protective grip area to save knuckles during repeated lump hammer blows. |
| Breaking back concrete edges and loose patches | OX concrete chisel | Built for tougher aggregate material where a standard brick bolster is too light. |
| General masonry trimming and correction work | OX masonry chisel | Solid all-round pattern for brick, block and patch repair work on refurbs. |
Common Buying and Usage Mistakes
- Buying a narrow cold chisel for brick splitting is a common mistake. It will work, but you will need more hits and you are more likely to end up with ragged breaks instead of a clean split.
- Using a wide brick bolster in tight chasing work wastes time and damages surrounding material. For joints, corners and narrow runs, use an OX cold chisel instead.
- Ignoring a handguard on heavy striking jobs usually ends with busted knuckles. If the chisel will be seeing repeated lump hammer use, the guarded version is the sensible buy.
- Striking a chisel with the wrong hammer shortens the life of both tools. Use a proper lump hammer with a clean striking face so the blows land square and the head does not mushroom early.
- Carrying on with a badly burred or damaged head is asking for trouble. Once the striking end starts deforming badly, dress it back safely or replace the chisel before fragments start breaking off.
Brick Bolster vs Cold Chisel vs Masonry Chisel
OX Brick Bolster
Best for cutting and trimming across the face of bricks and blocks. The wider blade moves more material in one hit, but it is not the tool for tight chasing or fine detail in narrow spots.
OX Cold Chisel
Better for narrower work such as joints, chasing and controlled chipping. It gives you more accuracy than a bolster, but it is slower when you need to split broader masonry cleanly.
OX Masonry Chisel
This sits in the middle as a general site option for brick, block and patch demolition. It is handy if you want one chisel for mixed work, though specialists will still prefer a dedicated bolster or cold chisel depending on the task.
With Handguard vs Without
A handguard model is the better call for repetitive striking, rough demo and anyone working fast in gloves. Plain patterns are fine for lighter, more controlled jobs where clearance matters more than finger protection.
Maintenance and Care
Clean Off Dust and Slurry
After use, wipe off brick dust, mortar and damp concrete residue before it hardens on the shaft and guard. It keeps your grip better and stops hidden moisture sitting on the steel.
Check the Striking Head
Have a look at the head after hard use. If it starts mushrooming or flaking, sort it before the next job. A damaged striking end can throw off sharp fragments when hit.
Keep the Edge Serviceable
A masonry chisel does not need to be razor sharp, but it should not be rounded over either. Once the cutting edge is badly battered, performance drops and you end up using more force than needed.
Store It Dry
Do not leave the chisel rolling about in wet rubble or at the bottom of a damp bucket. Dry storage cuts down rust and keeps the handle area and any handguard in better nick.
Replace When It Is Past It
If the edge is chipped beyond tidy use or the head is too deformed to strike safely, retire it. On site, a worn out chisel costs more in bad breaks and wasted time than a fresh one.

OX Bolster Chisel FAQs
What is the difference between a bolster and a cold chisel?
A bolster is usually wider and made for splitting or trimming across the face of brick, block and masonry. A cold chisel is narrower and better for chasing out, detail work and tighter areas where you need more control than coverage.
Does the OX bolster chisel come with a protective handguard?
Some OX bolster chisels do, especially the patterns aimed at heavier striking work. Not every model will have one, so check the product spec, but if you are doing plenty of lump hammer work a handguard version is well worth having.
What width options are available for OX brick bolsters?
OX brick bolsters are sold in different widths to suit different brick and block jobs. The exact sizes vary by model, but the rule is simple. Narrower widths give you more control, while wider blades are better for faster splitting across broader faces.
Are OX cold chisels drop-forged for heavy demolition work?
Yes, OX cold chisels are built for site punishment, and drop-forged construction is the sort of spec you want for repeated hammer impact. Always check the individual listing, but OX demolition hand tools are generally made for hard masonry and renovation work rather than light DIY use.
Will an OX brick bolster handle concrete as well?
For light concrete trimming, yes, but for regular concrete breaking you are better off with an OX concrete chisel or a tougher masonry pattern. A brick bolster is at its best on brick and block, not repeated punishment in hard aggregate.
Do I really need a handguard, or is that just extra bulk?
If you are only doing the odd careful trim, you can manage without one. If you are striking hard, working fast or using gloves in wet conditions, the extra protection is not gimmickry. It saves fingers and makes long sessions less of a pain.
