MORE INFO
Diamond compressed air sculptor's point chisel shank 10.2 mm. Conically ground. Open-die forged from hand-friendly octagonal steel.
Bildhau point chisels are slightly longer than other pneumatic chisels. This means that even deeper areas can be worked on comfortably and the chisel is still easy to grip.
The pneumatic tools with carbide insert from BAVARIA are suitable for hard stone such as granite, but also for softer types of stone such as marble or hard limestone.
The name Diamont refers to the great hardness of tungsten carbide, the material from which the tool cutting edges are made. Diamont tools do not contain any diamond components.
General information on carbide chisels:
Tapered carbide point chisels are available with a conical cut and, more rarely, with a pyramid cut. The pyramid-ground tools originally come from Italy and are very suitable for working with crystalline types of stone such as marble. Conically ground chisels are used for sandstone, hard limestone and granite.
Sculpting tools made of carbide or with carbide inserts are particularly suitable for working hard types of stone. Carbide tools need to be sharpened less frequently during work because the material is so strong that there is less abrasion than with tools made of forged steel. The carbide cutting edge therefore has a longer service life. However, if carbide chisels are ground to a very sharp point or thinly, careful working is required as carbide is a brittle material due to its hardness and can easily break when ground thinly. Levering movements during hammering can also lead to breakage or loosen the carbide pin from the steel casing.
The rule of thumb for hard stone is: the harder the stone, the blunter the cutting angle of the chisel should be. With hard stone such as granite, the chisel is placed at almost a right angle and the stone is virtually pulverised. The chisel therefore has a very blunt cutting edge. For crystalline stone such as hard marble, a more pointed tool with a sharper cutting edge is required. The chisel is set flat so that the stone can chip off without damaging the underlying crystalline structure.
