The T101A line from Bosch is engineered for precision cuts in Plexiglas, covering thicknesses from roughly 1/16 inch to 3/4 inch. These blades excel at fine, straight cuts and maintain consistent performance at higher speeds thanks to robust High Speed Steel construction. If your project requires accurate, narrow kerfs and clean edges on Plexiglass sheets, the T101A family provides reliable results with reduced edge chipping and longer blade life compared with standard steel blades.
- Designed for Plexiglas from 0.04″ to 0.75″ thick
- Ideal for fine, straight cuts
- High Speed Steel for longevity
Bosch T101A3 Plexiglass Blades
The T101A3 set from Bosch mirrors the T101A’s precision-focused design, but in a compact 3-piece format. These blades share the same capability to produce fine, straight cuts in Plexiglas with a 4-inch blade length and 14 TPI. They’re well-suited for detailed acrylic work where edge quality is essential. Made with High Speed Steel, they provide durability and stable performance, helping to minimize heat and edge damage during longer cuts on Plexiglass materials.
- 4-inch blades optimized for Plexiglas cutting
- 14 TPI for precise, straight cuts
- High Speed Steel construction for extended life

Buying Guide
Choosing the right blade for Plexiglass depends on material, thickness, and the desired edge quality. Here are key considerations to help you select blades that balance speed, durability, and finish. Understanding blade geometry and jigsaw compatibility will help you prevent common Plexiglass issues such as chipping, cracking, and heat warp.
- Blade material and tooth geometry: For Plexiglass, look for blades with mid-to-fine tooth counts (around 13–14 TPI) and bi-metal or carbide technology. Bi-metal blades with tapered backs reduce chatter and heat, while carbide-teeth resist wear on tougher edges. For PMMA specifically, blades labeled PMMA or PMMA-clean are optimized for clear acrylic finishes.
- Shank compatibility: T-shank blades are the most widely compatible across modern jigsaws. If your tool accepts U-shank blades, verify compatibility or use an adapter. The T-shank designs in this selection provide stable grip and reduced vibration, improving edge quality.
- Blade length and kerf: Shorter blades (around 4 inches) are ideal for tight curves and scroll cuts in Plexiglass, while longer blades (up to 3-5/8 inches) handle deeper cuts with fewer blade changes. A thinner kerf reduces material removal and heat, helping prevent melt along the cut line.
- Cutting speed and heat management: Plexiglass can melt if cut too aggressively or at high speeds. Choose blades designed to stay cool or engineered for heat resistance. Maintain steady feed pressure and avoid forcing the blade through thicker sections to keep edges smooth.
- Edge quality versus longevity: Blades with hardened edges or carbide teeth typically last longer, especially when cutting multiple panels or thicker Plexiglass. If you require frequent, repetitive cuts, investing in blades with longer life can reduce downtime and blade changes.
- Application specifics: For finishing work requiring razor-clean edges, consider blades marketed for PMMA or Plexiglas with a fine-tooth design. For rough cuts or internal curves, select a blade that combines a flexible blade body with precise tooth geometry to reduce edge chipping on the exit side.
- Maintenance and safety: Keep blades clean and free of plastic swarf. Clamp Plexiglass firmly and lay a protective tape over the cut line to minimize chipping. Wear eye protection and use proper PPE when working with sharp blades and plastic sheets.
