Hammer headed scutch chisels |
||||
 |
A hammer headed scutch chisel is the most common type of scutch chisel available. It has a flat head and is for use with hammers.
A hammer head is suitable for use with hammers because only the scutch comb holder has been hardened and tempered to give the shank some resilience for cutting hard stone/brick with a hammer. |
|||
 |
If the chisel shank has not been hardened, a hammer will splinter the chisel with the force exerted. If it has been hardened, the shank will bend slightly rather than splinter and break. | |||
Mallet headed scutch chisels |
||||
 |
A mallet headed scutch chisel has a mallet head for use with nylon/wooden mallets. It is shaped this way to spread the blow over a greater surface area which minimises the damage to the mallet.
The mallet headed scutch chisel is different to the hammer headed because the shank isn’t hardened. This means it will fracture or chip if it is hit with a hammer, hence why a mallet is more suitable. |

Pneumatic scutch chisels |
||||
 |
A pneumatic scutch chisel has an added length at one end to enable attachment to an SDS plus drill.
On the other end there are grooves to hold the scutch chisel in place. |
|||
 |
The pneumatic scutch chisel is simply pushed into the SDS plus drill to attach it, and then pushed down and out to release it.
When in use, the scutch chisel is moved up and down rapidly within the SDS plus drill in a hammering motion. This replicates the motion a normal scutch chisel makes but at a greater speed and with far less strain on the user. |
