Metal Shrinker Stretcher SG-18 with 70 mm Throat Depth, 1.5mm Capacity, Restoration Tools

KANG Industrial Metal Shrinker Stretcher SG-18

The Shrinker-Stretcher SG-18 with 70 mm Throat Depth is a high-quality, manual hand-operated metal forming tool designed for shrinking and stretching sheet metal to create precise curves, flanges, and complex shapes without heat or weakening the material. It includes two interchangeable jaws—one for shrinking (compressing metal for inside curves) and one for stretching (expanding metal for outside curves)—allowing seamless switching for versatile applications like wheel arches, door edges, custom panels, and compound contours in automotive, aviation, or general fabrication. With a generous 70 mm throat depth, it reaches deeper into larger sheets compared to shallow models, enabling work on broader panels without multiple setups. Key specifications include capacity for mild steel up to 1.5 mm thick, stainless steel up to 1 mm, and aluminium up to 2 mm, with a lightweight build for easy handling. This bench-mounted or vice-held tool is ideal for professional and hobbyist metalworkers seeking reliable, non-powered precision shaping.

Deep Reach Shrinker/Stretcher for Complex Projects. The 70 mm throat allows shaping farther from the edge, making it excellent for larger custom builds like 4x4 wheel arches, boat panels, or trailer modifications where deeper access reduces workarounds and saves time.

Higher Material Capacity. Handles thicker mild steel (1.5 mm) and aluminium (2 mm) than entry-level models (KANG SS-18), ideal for heavy-duty tasks in Australia's mining equipment repairs, structural fabrication, or marine applications involving durable metals.

Portable and Power-Free. At just 5.4 kg with manual lever operation, it's perfect for mobile setups in remote workshops, off-grid sites across the outback, or garages without reliable power—ensuring consistent performance in harsh conditions.

Versatile for Popular Hobbies. Suited for car restorations, hot rods, and custom bikes prevalent in the Australian scene, delivering pro results for enthusiasts in Sydney car clubs or rural sheds.

Durable Construction of the Shrinker-Stretcher. Heavy-duty cast iron frame and hardened jaws resist deformation and wear, ensuring the tool holds up to frequent use in tough workshop environments, from dusty rural sheds to humid coastal garages.
