Mayhew 5/8" Blade Width Blast Finish Cold Chisel (70209)
The Mayhew 5/8" Blade Width Blast Finish Cold Chisel (70209) is a specialized hand tool engineered for effective metalworking. Its 5/8-inch blade is designed to precisely cut and shape metals that are softer than the chisel's cutting edge. This tool is explicitly not intended for use on masonry materials. The blast finish provides a measure of rust deterrence and contributes to the tool's overall durability. Being made in the USA ensures adherence to manufacturing standards and quality craftsmanship. Its hexagonal body provides a secure grip and prevents rolling on flat surfaces.

Preparation: Always wear appropriate personal protective equipment, including safety glasses or goggles, heavy-duty gloves, and hearing protection before starting any work with a cold chisel. Ensure your workpiece is securely clamped or held in a vise to prevent movement during striking.
Positioning the Chisel: Place the cutting edge of the 5/8" Mayhew cold chisel precisely on the mark where you intend to cut or shape the metal. Angle the chisel correctly for the desired cut.
Striking: Using a hammer of appropriate weight, strike the striking end of the chisel firmly and squarely. Avoid glancing blows, as this can damage the chisel or cause injury.
Cutting/Shaping: Continue striking the chisel along your desired line or area, adjusting the chisel's position as needed. For cutting through metal, make multiple strikes along the same line. For shaping, use controlled strikes to gradually remove material.
Finishing: After cutting or shaping, inspect your work. You may need to file or grind the edges to achieve a smooth finish. Clean the chisel after use and store it in a dry place.
