Glass Cutters

Glass cutters help you score and snap clean lines in glass and acrylic, saving time, reducing waste, and producing professional edges for windows, mirrors, stained glass, picture framing, and display cases. A quality cutter makes a controlled score that runs predictably, so breaks are cleaner and polishing needs are minimal. Whether you’re a glazier, artist, or DIY maker, choosing the right tool and technique yields crisp cuts with fewer chips and less frustration.

You’ll find several types to match material and project needs. Straight-handle and pistol-grip bodies offer different ergonomics; pistol grips often give better leverage for long scores. Cutting wheels are typically tungsten carbide or diamond; carbide is durable and budget-friendly, while diamond cutters excel at smooth, consistent scoring on harder glass. Oil-fed cutters keep the wheel lubricated for quieter operation and cleaner scores. Specialized tools include circle cutters for mirrors and tabletops, strip cutters for repeat widths, and running or breaking pliers for opening the score. For plastic glazing, acrylic scoring knives deliver clean snap-cuts without melting the edge.

Tips for choosing and using:
- Match wheel angle to thickness: lower angles (around 120°) suit thin glass; higher angles (around 135°) favor thicker stock.
- Pick a comfortable handle and weight; control reduces hand fatigue and chipping.
- For mirrors and coated glass, score on the glass side, not the backing.
- Use a safety ruler or straightedge and even pressure; one firm pass is better than multiple light passes.
- Support the sheet on a flat surface; tap gently to “run” the score before breaking.
- Pair with running pliers, grozing pliers, and a cutting mat for safer, cleaner results.
- Maintain your cutter: keep the wheel clean, refill oil in oil-fed models, and replace worn heads.

Safety matters: wear cut-resistant gloves and eye protection, brush away shards, and store cutters with caps. Buy glass cutters, oil, and accessories here to equip your shop for stained glass, glazing, and mirror projects with precision and confidence.
