MORE INFO

Diamond carbide pneumatic claw chisel shank 12.5 mm. Total length approx. 200 mm - 220 mm.

Robust claw chisel made from octagonal steel with carbide claw chisels. Each tooth is individually fitted with a carbide round pin and enclosed all round by the steel body. The claw chisels are supplied with pointed teeth as standard. They are available with flat teeth on request at no extra charge.

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:

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.

Carbide chisels can also be used for processing sandstone. As sandstone is highly abrasive, forged steel chisels can wear relatively quickly. Carbide cutting edges also have a longer service life here due to their hardness. However, it must be taken into account that the carbide pins are usually set in steel.

As with crystalline stone, pointed chisels tend to be used for working sandstone: The aim with this type of stone is to destroy the bond between the sand particles when striking, for which a pointed tool is better suited than a blunt one. But the same applies here: for very hard sandstone, use less pointed chisels, which are less likely to break.
