MORE INFO

Pyramidal cut for crystalline rock. With mallet head. Length 210 mm.

The carbide shaped carbide point chisel from KAPRA has a pyramidal grind - a special feature that is otherwise only available in Italy. This sharp-edged cut is ideal for cutting crystalline stones such as marble, but also hard limestone. The point chisel is used to carve out the shape of the sculpture as far as possible.

General information on carbide chisels:

Sculpting chisels made of carbide or with carbide inserts are particularly suitable for working on 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.

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.

Tapered carbide point chisels are available with a conical cut and, more rarely, with a pyramid cut. The pyramid-ground tools come from Italy and are very suitable for processing crystalline types of stone such as marble. Conically ground chisels are used for sandstone, hard limestone and granite.

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. However, the same applies here: for very hard sandstone, use less pointed chisels that are less likely to break.

The KAPRA carbide chisels are manufactured by BAVARIA Steinmetzwerkzeuge according to the requirements of bildhau. Find out more about the special features, production and quality of BAVARIA carbide tools in an interview with Andreas Weber, owner of BAVARIA Steinmetzwerkzeuge.
