5-piece chisel set in free canvas bag. Optionally with bronze mallet. With free-standing carbide plate. With hammerhead.
The carbide chisels are ideal for fine detail work in marble and limestone and have the following properties:
The free-standing carbide plate allows a good view of the workpiece. The ratio of cutting edge width to chisel thickness is balanced. The chisels have extremely sharply ground cutting edges and a flat cutting edge angle that merges into the chisel body. The chisels have an ideal length for sculpting work and are made of high quality carbide.
The very fine and sharply ground cutting edges allow crystalline stone and limestone to chip easily and enable a precise strike for detailed work and lettering. The chisels require careful handling: 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 break easily when ground thin.
The set contains 5 GUILLET quality chisels with a free-standing carbide plate in a practical Kanva bag:
1 lettering chisel Ø 10 mm, 4 mm wide
1 lettering chisel Ø 10 mm, 6 mm wide
1 lettering chisel Ø 10 mm, 8 mm wide
1 flat chisel Ø 8 mm, 4 mm wide
1 flat chisel Ø 8 mm, 8 mm wide
+ free Kanva bag
optionally with bronze mallet 400 gr
Please note the special instructions for using the GUILLET chisels with free-standing carbide blade:
The fine GUILLET carbide chisels are very suitable for carving out details and lettering from crystalline rock and hard limestone. The chisels should be loaded as evenly as possible and should not be used on one side, otherwise they may tilt and break. Levering movements when striking can also lead to breakage. GUILLET carbide chisels are not suitable for working with a heavy mason's hammer or for blasting or rough removal of stone!
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 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.
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 positioned 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 working sandstone. As sandstone is highly abrasive, forged steel chisels can wear relatively quickly. Carbide cutting edges have a longer service life due to their hardness. However, it should be noted that the carbide pins are usually set in steel.
As with crystalline rock, pointed chisels tend to be used for working sandstone: the aim with this type of rock 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.
KAPRA carbide chisels are manufactured by BAVARIA Steinmetzwerkzeuge according to the requirements of bildhau. You can find out more about the special features, production and quality of BAVARIA carbide tools in an interview with Andreas Weber, owner of BAVARIA Steinmetzwerkzeuge.
