Crown Tools 242EPM 1/2 Inch Powder Metallurgy Ellsworth Gouge is one of Crowns exclusive new range of 'elite' Pro-PM turning chisels. Made from an advanced Powder Metal, the molten steel has been compressed and sintered, giving the tool a cutting edge which lasts up to four or five times that of a conventional High Speed Steel tool. The chisel is hardened to between 66-Degrees and 69-Degrees Rockwell, enabling the tools to have a vastly superior wear resistance, excellent grindability, superior toughness, a high working hardness and a high retention of hardness. The ergonomically designed stained black ash handle fitted to this tool makes the finished chisel unbeatable. 16-Inch 406-mm Black Ash Handle.
