Rubberised lettering lettering chisel with shank 10.2 mm carbide pneumatic tool shank 10.2 mm

GEDIK pneumatic lettering chisel with rubber coating with shank 6, Ø 10.2 mm. Length 200 mm.

The rubber coating minimises vibration and reduces the feeling of cold when working.

The air 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.

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.
