Mayhew 7/8-22mm x 18″ Black Oxide Long Cold Chisel (10219)

Description

The Mayhew 7/8-22mm x 18″ Black Oxide Long Cold Chisel (10219) is a high-quality, professional-grade tool crafted for precise cutting and shaping of metals. Designed and manufactured in the USA, this chisel provides reliable performance for various metalworking applications. Its 7/8-inch (22mm) cutting edge combined with an 18-inch overall length offers good reach and leverage for demanding tasks. The distinctive black oxide finish not only gives the tool a professional look but also provides an essential layer of protection against rust and corrosion, extending its lifespan.

This cold chisel is specifically engineered for working with metals that are softer than the chisel’s own cutting edge. It is important to note that this tool is not intended for use on masonry materials, ensuring its longevity and proper function. The design incorporates a parabolic head, a safety feature that minimizes the risk of mushrooming and chipping when the chisel is struck, enhancing user safety during operation. With its robust construction and thoughtful design, the Mayhew 10219 cold chisel stands as a dependable tool for metal cutting and shaping.

KEY FEATURES AND BENEFITS:

• Precise Metal Cutting: The 7/8-22mm blade width is specifically designed to cut and shape metals that are softer than the chisel’s cutting edge, allowing for accurate work.
• Enhanced Rust Protection: A black oxide finish is applied to the chisel, providing an additional layer of defense against rust and corrosion, which helps maintain the tool’s condition over time.
• Extended Reach: With an 18-inch overall length, this long cold chisel offers extended reach, making it easier to access workpieces in challenging positions and apply force effectively.
• Reduced Chipping Risk: Features a parabolic head designed to minimize mushrooming and chipping on the struck end, improving safety during use.
• American Made Quality: Manufactured in the USA, ensuring adherence to high production standards and supporting domestic craftsmanship.
• Professional Grade: Meets or exceeds ASME B107.401 and US government GGG-C-313D standards, indicating its suitability for professional applications.

HOW TO USE:

1. Safety First: Always wear appropriate personal protective equipment, including safety goggles and gloves, before using the cold chisel.
2. Secure the Workpiece: Place the metal workpiece on a stable, flat surface, such as an anvil or a sturdy workbench. Ensure the workpiece is securely clamped or held to prevent movement during cutting.
3. Position the Chisel: Hold the cold chisel firmly at the desired cutting line on the metal. Angle the chisel slightly away from the waste material, typically at an angle of 15 to 20 degrees relative to the surface.
4. Strike the Chisel: Using a hammer (preferably a ball-peen or club hammer of appropriate weight), strike the parabolic head of the chisel with controlled force. Start with lighter taps to establish the cut, then increase force as needed.
5. Follow the Line: Continue striking the chisel along the cutting line, moving it incrementally to ensure a clean and consistent cut. For longer cuts, reposition the chisel along the line.
6. Clean Up: Once the cut is complete, carefully remove any detached metal pieces. Inspect the cut edge for smoothness and accuracy.
