REBIT carbide lettering chisel

Length approx. 170 mm. Weight approx. 200 g.

The REBIT tools from the Norwegian company MONARK originally come from the mining industry and have therefore been developed for the toughest requirements in stone processing. The carbide is of exceptional quality and the entire processing is extremely resistant. The tools formerly developed by EPIROC are still produced in Sweden. We recommend the tools for use in granite and other hard stone.

Please note: We are convinced of the REBIT tools and would like to offer our customers as wide a selection of these special tools as possible. However, it is not possible for us to have all tools in stock at all times. We therefore apologise for any longer delivery times.

Information on carbide tools:

Sculpting tools made of carbide or with carbide inserts are particularly suitable for processing 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. However, the same applies here: for very hard sandstone, use a less pointed chisel that is less likely to break.
