FAQs
Can these pliers be used on thick glass?
They are designed for standard stained glass and glass fusing thicknesses. Use the adjustable screw to calibrate pressure, but avoid using excessive force on tempered or extremely thick glass.
Are the rubber tips replaceable?
Yes, standard protective rubber tips for these types of pliers are generally available, but you should prioritize keeping the originals clean to extend their life.
Do I need to lubricate the pliers?
A drop of light machine oil on the pivot point can help keep the movement smooth, but be sure to wipe away any excess so it does not transfer to your glass projects.
Can I use these for metal jewelry making?
Yes, they are excellent for installing key fob hardware because the rubber tips prevent the metal clamps from getting scratched during the crimping process.
What is the difference between the two pliers?
The running pliers are for executing clean breaks along a full score line, while the breaker grozer pliers are for nibbling glass or breaking off smaller, irregular sections.
Troubleshooting
The glass is not breaking cleanly along the score line.
Check the set screw adjustment on the running pliers; you may need to apply slightly more pressure or ensure the center mark is perfectly aligned with the score.
The rubber tips are leaving marks or slipping.
Wipe the rubber tips with a damp cloth to remove oils, and ensure they are pushed firmly onto the metal jaw ends.

Setup, Compatibility & Care
To keep your Swpeet pliers in peak condition, ensure the set screw on the running pliers is kept clean and free of glass dust or debris. Before each project, check that the rubber tip covers are snugly fitted; if they appear worn or loose, replace them immediately to avoid direct metal-on-glass contact, which can cause cracking. After each use, wipe down the tools with a dry cloth to remove glass fragments. Store the pliers in a cool, dry place, ideally in a drawer or tool roll to prevent the rubber tips from getting pinched or damaged.
