Carbide pneumatic carving chisel shank 10.2 mm carbide 10 mm blade 10 mm

Diamont pneumatic lettering chisel, shank 6, Ø 10.2 mm. Total length 270 mm. In a handy, free-form forged octagonal shape.

The lettering 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 carbide lettering chisel is suitable for soft to medium-hard stone, such as marble, limestone and serpentine.

The name Diamont refers to the high 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:

Sculpting tools made of carbide or with carbide inserts are particularly suitable for working hard types of stone. Carbide tools need to be resharpened 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 very sharp or thin, careful working is required, as carbide is a brittle material due to its hardness and can easily break when ground thin. Levering movements when 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.
