1" Metal Running Pliers for Stained Glass

Running pliers take the guesswork out of breaking glass — they apply even, controlled pressure along your score line so you get a clean break every time. These 8" metal running pliers from Diamond Tech are a reliable studio staple, built for consistent performance with a lifetime guarantee (replaceable parts excluded).

How They Work

Position the curved jaw at the end of your score line on the edge of the glass, align the centering mark with your score, and gently squeeze. The 1" wide curved jaw distributes equal pressure on both sides of the score — no uneven breaks, no wasted glass.

Setting Up for a Perfect Break

Before you cut, place the running pliers on your glass and gently close them. Tighten the adjustment screw all the way down, then back it off about half a turn. This sets the jaw opening to just slightly less than your glass thickness — the ideal calibration for a clean, controlled run every time.
