Last Updated on Dec 28, 2025 by Happy Dieter

Are you looking for a precise and efficient method to cut plexiglass using a jigsaw with dremel? Look no further than your trusted Dremel rotary tool. Cutting acrylic with a Dremel or jigsaw can be a breeze when you have the right technique and tools at hand. In this step-by-step guide, we’ll walk you through the process of cutting plexiglass with a Dremel, jigsaw, ensuring clean cuts and professional results.

Before we dive into the cutting process, it’s essential to follow some best practices to ensure success with saw and acrylic or plexiglass sheets. Firstly, leave the factory-provided protective film on the acrylic plexiglass for as long as possible to protect it from scratches and cracks. Secondly, wear safety glasses and gloves to protect yourself during the cutting process of plexiglass sheets using a saw.

Key Takeaways:

• Use a Dremel rotary tool for precise and efficient cuts on plexiglass.

• Leave the protective film on the acrylic plexiglass to prevent damage.

• Wear safety glasses and gloves for added protection.

How to Cut Plexiglass with a Dremel: Straight Plunge Cuts

When it comes to cutting plexiglass with a Dremel, straight plunge cuts are a common technique. Here’s a step-by-step guide to help you achieve clean and precise cuts on plexiglass sheets.

1. Start by marking the intended cut line on the plexiglass using a permanent marker or Sharpie. This will serve as your guide throughout the cutting process of plexiglass sheets.

2. Securely clamp and cut the plexiglass workpiece, ensuring that a protective layer is placed underneath to prevent damage to the work table.

3. Install the EZ476 plastic cutting disc onto your Dremel to cut plexiglass sheets. This specialized cutting wheel is designed for clean cuts on acrylic, vinyl, and plexiglass materials.

4. Set the Dremel speed between 10000 and 15000 RPM, following the manufacturer’s recommendations for cutting plexiglass.

5. Gently score the cutline on the plexiglass using the cutting bit. Move the Dremel in even movements without applying excessive pressure to avoid creating cracks or melting the material while cutting.

6. Once the entire cutline is scored, continue passing the cutting bit along the cutline until it stretches halfway through the intended cutting depth.

7. At this point, you have two options. You can carefully snap off the workpiece along the cutline, or you can continue cutting all the way through by repeating the previous step until the cut is complete.

Remember to work slowly and steadily, allowing the cutting bit to do the work. Taking breaks to let the cutting bit and the plexiglass cool down if necessary can help prevent overheating and ensure smoother cuts. With practice, you’ll be able to master the technique of straight plunge cuts and achieve professional results with your Dremel.

Benefits of Straight Plunge Cuts

• Straight plunge cuts are ideal for creating precise, straight lines in plexiglass.

• This cutting technique ensures clean edges without the risk of chipping or cracking the material.

• Straight plunge cuts are versatile and can be used for various projects that require accurate and straight cuts in plexiglass.

How to Cut Plexiglass with a Dremel: Curved Cuts

When it comes to cutting curved cuts in plexiglass, using a Dremel requires a slightly different technique. Here’s how you can achieve clean and precise curved cuts:

1. Start by marking the intended cut line on the plexiglass using a permanent marker or Sharpie. This will serve as your guide throughout the cutting process.

2. Securely clamp and cut the plexiglass workpiece, ensuring there is a protective layer underneath to prevent any damage to the work surface.

3. Install a 1¼” carbide-coated cutting and shaping wheel on your Dremel tool. A popular choice for curved cuts is the Dremel 543, specifically designed for cutting through plastics.

4. Set the Dremel speed according to the manufacturer’s recommendations for cutting plexiglass. This will help prevent overheating and ensure optimal cutting performance.

5. Make gentle and even movements along the marked cutline, using the cutting bit to score the surface. Apply moderate pressure to create a shallow groove that stretches halfway through the cutting depth.

6. Continue scoring the cutline until you have achieved the desired depth or have cut through the plexiglass, depending on your project requirements.

7. Once the curved cut is complete, you can either snap off the workpiece along the cutline or use a fine file or sandpaper to smooth the edges and achieve a finished look.

Pro Tip:

Take your time and apply consistent pressure to ensure a clean and precise curved cut. It’s also recommended to practice on scrap pieces of plexiglass before working on your actual project to gain confidence and refine your cutting technique.

Remember to always wear appropriate safety gear, such as safety glasses and gloves, when cutting plexiglass with a Dremel.

Conclusion

When it comes to cutting plexiglass, using a Dremel can offer precise and efficient results. By following the proper techniques and utilizing the right tools, you can achieve clean cuts without damaging the material.

One important tip is to protect the cut workpiece by leaving the factory-provided protective film on for as long as possible. This helps to prevent scratches and cracks during the cutting process.

For straight plunge cuts, the recommended Dremel bit is the EZ476 plastic cutting wheel. This specially designed wheel ensures clean cuts on acrylic and vinyl. On the other hand, if you need to make curved cuts, the 1¼” carbide-coated cutting and shaping wheel, such as the Dremel 543, is the ideal option.

Remember to always follow the step-by-step guide provided and take safety precautions, such as wearing safety glasses, gloves, and cuts. Additionally, allow the cutting bit and workpiece to cool down periodically to prevent overheating. With practice and proper care, cutting plexiglass with a Dremel can become an easy and effective process.

Which Method is Safer for Cutting Plexiglass, Using a Dremel or Cutting by Hand?

When it comes to safety, cutting plexiglass by hand is the preferred method. While a Dremel can provide precise cuts, it also creates more heat and potential for cracks. Using a scoring tool and snapping the plexiglass along the line is a safer and cleaner approach.
