Precision Tungsten Sharpening and Guide Rail Set • Constructed from durable brass and tungsten materials for longlasting performance and precision results. • Guide rails sized at 0/40, 1/16 inch, 3/32 inch, and 1/8 inch provide accurate alignment for a variety of tungsten electrode diameters. • Includes a tungsten sharpening tool with four angled holes for precise tip shaping at 22.5°, 20°, 15°, and 10° (tip angles equivalent to 45°, 40°, 30°, and 20°). Ideal for achieving consistent geometry that improves arc starts and weld quality. • Each grinding size is served by 3 dedicated holes, offering a total of 12 holes for efficient, repeatable sharpening. • Compatible with most rotary tools featuring a 3/412 thread, including Black and Decker, Milwaukee, Bosch, and Dremel models. Key benefits: • Ensures consistent tungsten electrode preparation, reducing welding defects and improving arc stability. • Streamlines workflow by providing multiple angle and size options in a single compact tool. • Saves time and effort compared to manual or improvised sharpening methods. Applications: 1. Ideal for TIG welding professionals and hobbyists who require precise tungsten shaping for quality welds. 2. Useful in fabrication shops where multiple tungsten sizes and tip angles are needed for different welding projects. 3. Suitable for maintenance and operations demanding quick tip preparation without changing tools. This set delivers accurate, repeatable results, robust construction, and broad tool compatibility, making it a reliable solution for anyone working with tungsten electrodes in TIG welding applications.
