sculptor's point chisel carbide with hammerhead

Diamont point chisel. With hammerhead for processing granite, among other things. Length approx. 250 mm. Made from octagonal steel. With conical cut.

The length of the carbide pointed chisel pin is 20 mm for all point chisels. The diameter of the tungsten carbide pin is as follows for the irons

8 x 8 mm: Ø 4 mm
10 x 10 mm: Ø 5 mm
12 x 12 mm: Ø 5 mm
14 x 14 mm: Ø 6 mm
16 x 16 mm: Ø 6 mm

BAVARIA tools with carbide inserts 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 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 bits:

Tapered carbide point chisels are available with a conical grind and, more rarely, with a pyramidal grind. The pyramid-ground tools originally come from Italy and are very suitable for working with crystalline types of stone such as marble. For sandstone, hard limestone and granite, conical ground chisels tend to be used.

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, as 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.
