Good maintenance of your carbide chisels lets you cut faster and more accurately. However, improper grinding can damage the carbide and cause tool failure.

To extend the life of your carbide-tipped chisel:

• When grinding, leave corners slightly beveled. Very sharp or pointed carbide may break on harder stone
• Don't forget to grind the shank end or striking head frequently to maintain the correct "as-new" shape for safe performance.
• Use care when storing or transporting carbide tools. Although tough and durable, carbide can break, especially when struck by another carbide tool.
• Never quench your carbide tool after grinding. Sudden changes in temperature can cause cracking or chipping of the tip, so always air-cool your tool after grinding.
