About this subject

The woodturning chisel is a fundamental tool in woodturning, used on lathes to shape cylindrical or symmetrical pieces. There are various types, such as the roughing gouge, skew chisel, and spindle gouge. Each has a specific geometry for different operations: roughing, cutting, hollowing, and finishing. The blade is typically made of high-speed steel (HSS) or carbon steel, hardened to maintain an edge. The handle, often made of resin-impregnated wood, provides a secure grip. Woodturning dates back to antiquity, with evidence of primitive lathes in Egypt and ancient Rome. In Brazil, the technique arrived with colonizers and developed in regions like the Paraíba Valley, where artisans produce turned furniture and objects. Edge maintenance is crucial: sharpening on a stone or machine must be done at specific angles, usually between 30 and 40 degrees. Common mistakes include incorrect angle or overheating, which can damage the temper. Use of PPE like goggles and face shield is recommended, as wood chips and metal can fly during work. Fun fact: the word "lathe" comes from the Latin "tornus", meaning "to turn".
