Durston® Round Mandrel Forming Plier 170mm

Perfect coils and heavy-wire loops, every single time. If you try to make a long coil or perfectly uniform jump rings with standard round-nose pliers, you’ll quickly realize a frustrating truth: standard pliers are cone-shaped, which means your loops will be different sizes. The Durston® Round Mandrel Forming Pliers fix this instantly. Engineered by the UK's premier jewelry tool manufacturer, these heavy-duty 170mm pliers feature dual non-tapered, perfectly parallel jaws. They are built incredibly tough to conquer heavy-gauge wire, allowing you to wrap flawless, consistent coils without warping your tool or straining your hands.

Why You’ll Love It

• The "Non-Tapered" Secret: Both jaws are perfect cylinders from base to tip. This means no matter where you grip the wire along the jaw, your loops, coils, and bails will be perfectly uniform and parallel—never cone-shaped.

• Built for Heavy Gauge Wire: Standard pliers bend or cross over when you try to shape thick 12G or 14G wire. Forged from high-grade British steel, these Durston mandrels are engineered specifically to manipulate heavy structural wire without flinching.

• Mass-Produce Jump Rings: Want to make your own chainmaille rings? Simply wrap your wire around the barrel a dozen times to create a perfectly uniform spring coil, then saw-cut it down the middle for instant, matching jump rings.

• Smooth, Mar-Free Surface: The solid steel barrels are expertly polished. They provide an unyielding grip to bend thick metals, yet are smooth enough to prevent deep gouges and tool marks on your wire.

• Ergonomic Leverage (170mm): Bending thick wire takes serious force. The elongated 170mm frame provides massive mechanical leverage, while the thick poly handles offer a comfortable, shock-absorbing grip that saves your wrists from early fatigue.
