Bosch Plexiglass Specialty Jigsaw Blade Review

Clean, Chip-Free Cuts in 1/8" Acrylic

Cutting acrylic sheet cleanly is one of those jobs that looks easy until you actually try it. Standard wood or metal jigsaw blades tend to chatter, melt the plastic, or leave a frosted, chipped edge that needs heavy sanding and polishing afterward. That’s why I was pleasantly surprised by how well the Bosch Plexiglass Specialty Jigsaw Blade performs on 1/8" (3 mm) acrylic.

Designed Specifically for Acrylic

Bosch designed this blade with a very fine-tooth geometry and a ground cutting edge optimized for brittle plastics. Instead of tearing at the surface, the teeth shear the material smoothly, minimizing stress cracking and edge chipping. The result is a cut that looks more like it came off a table saw with a plastic blade than a handheld jigsaw.

Near-Perfect Edge Quality

On straight cuts in 1/8" cast acrylic sheet, the edge quality is impressively clean:

• No visible chipping along the cut line

• No melted beads re-fusing to the edge

• Minimal haze, even before polishing

• Square, smooth profile suitable for solvent welding or flame polishing

In many cases, the edge is good enough to use as-cut for display panels, light diffusers, or instrument covers without additional finishing.

Reduced Heat and Stress Cracking

A common problem when cutting plexiglass is heat buildup, which causes melting, re-welding, and micro-cracks that show up later. The Bosch plexiglass blade runs noticeably cooler because it clears chips efficiently and doesn’t rub aggressively. This is especially important when making long straight cuts where heat can accumulate.

Best Cutting Technique

To get the best results:

• Use a medium jigsaw speed (not full throttle)

• Clamp the acrylic firmly to prevent vibration

• Support both sides of the cut

• Use painter’s tape on the surface for extra scratch protection

• Let the blade do the work—don’t force the feed rate

With proper support and a guide fence, straight cuts come out remarkably straight and polished-looking.

Ideal Applications

This blade is excellent for:

• Control panel faceplates

• Light boxes and LED diffusers

• Display cases

• Window panels for enclosures

• Sign backing and lettering panels

For anyone working with thin acrylic on a regular basis, it turns a jigsaw into a surprisingly precise plastic-cutting tool.

Final Thoughts

The Bosch Plexiglass Specialty Jigsaw Blade proves that the right blade makes all the difference. On 1/8" acrylic sheet, it produces an edge that is nearly perfect straight off the saw—clean, square, and chip-free. For hobbyists, fabricators, and metalworkers who also work with plastics, this blade is easily one of the best upgrades you can make to your cutting setup.
