The Best Saw Types for Cutting Plexiglass

Introduction

Plexiglass, a popular transparent thermoplastic material known for its durability and translucency, requires a specific approach when it comes to cutting. The wrong tool or technique can easily lead to cracked or melted edges. In this article, we will discuss the recommended saw types for cutting plexiglass, along with some invaluable tips for achieving a clean and polished finish.

Recommended Jigsaw Blades

For precision cutting, a jigsaw blade with a fine tooth count specifically designed for plastic or acrylic materials is highly recommended. A T-shank blade is often preferred as it provides a cleaner cut and reduces the risk of cracking. These blades, while more expensive, offer the best results when working with plexiglass. If you frequently need to cut plexiglass, investing in a few high-quality jigsaw blades is worth the cost.

Table Saw Blade Recommendations

For those looking to cut large quantities or in a professional setting, the plastic supply houses often use a high-count toothed carbide circular saw blade with a 'triple chip grind' configuration. This blade is pushed through the cut quickly, making it a fast and efficient option. However, it requires careful use - cutting too slowly can lead to melted edges and a sticky cut, while cutting too quickly can result in a ragged finish. This type of blade is expensive, so many turn to the supply houses for cutting services. If you need to cut a large number of pieces, purchasing the special blade is a cost-effective solution.

Drilling Tips for Plexiglass

When drilling holes in plexiglass, it's essential to use drills specifically designed for this material. These drills have very pointy tips, almost like a pencil tip, which help prevent cracking during the drilling process. To back up the hole, use a block of wood to support the drill. Drill at a moderate speed, neither too slow nor too fast, to avoid damaging the plexiglass. This method ensures clean and secure holes.

Polishing the Cut Edges

After cutting through the plexiglass, it's essential to polish the edges for a clean and professional finish. One method is to pass a torch flame over the cut edge while moving the flame at a controlled pace. Both too fast and too slow can result in uneven or smudged results. Practicing patience and control during this process will yield better results.

Conclusion

Cutting plexiglass requires the right tools and techniques to ensure a clean, professional, and undamaged result. From using jigsaw blades with fine teeth to utilizing specialized table saw blades and drills, the key is to be patient, precise, and methodical. By following these recommendations, you can achieve the best results when cutting plexiglass for your projects.
