7 Best Jigsaw Blades for Plexiglass 2025

If you demand laser-precise cuts in plexiglass without chipping or cracking, the BOSCH T101A is a standout performer. These 4-inch, 14 TPI High Speed Steel blades are engineered specifically for smooth, straight cuts in acrylic sheets from 5/64″ to 3/4″ thick, making them ideal for signage, displays, and custom installations. The high tooth count ensures a clean, polished edge while minimizing heat buildup—critical when working with thermoplastics that can melt under friction. For professionals and serious DIYers, this blade eliminates the guesswork and delivers repeatable, burr-free results every time.

In real-world testing, these blades slice through 1/2″ plexiglass with remarkable stability and minimal vibration, thanks to their optimized tooth geometry and rigid shank design. The 2 3/4″ working length provides ample depth for most tasks, and the T-shank fits securely in most modern jigsaws without wobble. While they excel in straight-line cutting, intricate curves can cause slight drag due to the aggressive tooth count—best reserved for linear or gently curved cuts. They also double as capable metal-cutting blades (up to 3/8″ steel), adding unexpected versatility.

Compared to budget alternatives like the Romeda 10-piece set, the BOSCH T101A offers superior consistency and edge retention, especially in demanding applications. It’s not the cheapest option, but its precision-focused engineering makes it a go-to for fabricators who can’t afford rework. When stacked against the T102BF, it trades some finesse for raw durability—this is the workhorse choice for shops that cut both acrylic and light metal regularly.

When flawless, chip-free edges on plexiglass are non-negotiable, the Bosch T102BF rises to the challenge with surgical accuracy. Featuring a ground and tapered back tooth design, these 13 TPI blades reduce friction and prevent grabbing—two common culprits of cracked acrylic. At 3-5/8″ long, they’re optimized for controlled, shallow-depth cuts in sheets up to 3/4″ thick, making them perfect for delicate trim work or display fabrication. The bi-metal construction ensures longevity, especially when switching between materials, which is a huge plus for workshops juggling multiple projects.

During hands-on use, the T102BF glides through 3/8″ PMMA with a smoothness that rivals router finishes—no sanding required. The tapered teeth initiate clean entry and exit cuts, drastically reducing the risk of edge fracturing, even on unsupported overhangs. It handles slight curves better than higher TPI blades, though aggressive bends still require slower feed rates. While not designed for metal, it can manage thin aluminum with care—but best reserved for plastics to maximize blade life.

Against the BOSCH T101A, the T102BF delivers finer surface quality at the cost of slightly reduced durability. It’s the precision scalpel to the T101A’s utility knife. For users prioritizing finish over frequency of use, this is the smarter pick. Compared to bulk sets like the 50-piece contractor pack, the T102BF offers specialized performance you simply can’t get from generic blades.

For contractors and makers who tackle mixed-material jobs daily, the 50-piece Contractor Jigsaw Blade Set is a game-changer in efficiency and preparedness. This comprehensive assortment includes popular Bosch-compatible models like T101AO and T144D, covering everything from fine wood to mild steel and plastic—including plexiglass. The organized storage case keeps blades accessible and prevents loss, a small but critical detail on busy job sites. While not every blade is optimized for acrylic, the inclusion of T101-series variants means you’ll always have a suitable option for clean plastic cuts.

In practice, the set shines when project demands shift rapidly—switching from framing wood to plastic trim becomes seamless. Blades like the T101B deliver decent results on plexiglass, though they lack the specialized tooth grind of the T102BF, leading to slightly rougher edges. The T-shank design ensures compatibility with 90% of modern saws, and the high-speed steel construction holds up well under moderate use. However, for dedicated acrylic work, you’ll still want to reach for a purpose-built blade.

Compared to the Bosch T102BF or T101A, this set isn’t the best-in-class for plexiglass, but it’s unmatched in versatility and readiness. It’s the ultimate “always-have-the-right-blade” solution, ideal for handymen, remodelers, or makerspaces. Against the 20-piece multi-material set, it offers greater volume and variety, making it a smarter long-term investment despite the higher initial cost.

The Romeda 10-piece jigsaw blade set delivers surprising performance for its rock-bottom price, making it a compelling entry point for casual users and weekend warriors. With a mix of T101-series blades like the T101AO and T101BR, it includes options capable of clean cuts in plexiglass and plastic, though results depend heavily on technique and feed rate. Constructed from SK5 high-carbon steel, these blades claim superior wear resistance—on par with or exceeding some bi-metal variants in light-duty use.

In real-world tests, the T101AO variant handled 1/4″ acrylic reasonably well, producing smooth edges when used at low speed with steady pressure. However, on thicker sheets (over 1/2″), the lack of specialized tooth geometry led to micro-chipping and slight melting—a sign of excessive friction. The T-shank design clicks in securely and resists wobble, a big win for ease of use. While not built for industrial throughput, it’s perfect for occasional DIY tasks like cutting plastic enclosures or trim.

Against the Bosch T102BF, it’s clearly a step down in precision and finish quality—but that’s expected at this price tier. Where it outshines competitors is in accessibility and breadth for the cost. For users who need a little of everything without breaking the bank, this set is a no-brainer starter kit. Compared to the 50-piece contractor set, it’s less comprehensive but ideal for those just getting started.

Engineered for industrial-grade acrylic fabrication, the Bosch PRO Plastics PMMA Clean T102BF is the gold standard for professionals who demand flawless, production-ready cuts in PMMA. With a precise 13 TPI count and optimized tooth geometry for thermoplastics, this blade slices through acrylic up to 20 mm (about 3/4″) with zero chipping or cracking—critical in signage, display, and architectural applications. The 92 mm length (3.6″) balances reach and control, while the T-shank ensures vibration-free operation in high-RPM saws.

Field testing confirms its superiority in high-volume plastic cutting environments—it maintains edge sharpness over dozens of cuts without noticeable degradation. The blade’s design minimizes heat buildup, preventing the melting and warping that plague cheaper alternatives. It’s not meant for metal or wood, but within its domain, it performs like a CNC router bit. Install one, and you’ll immediately notice smoother feed rates and cleaner exits, even on unsupported edges.

Compared to the standard T102BF (B00CZEGW7E), this PRO version is identical in specs but marketed toward industrial users—likely with tighter quality control. Against the BOSCH T101A, it offers superior finish quality on pure plastic jobs. For shops where finish = profit, this blade is worth every penny. It’s the definitive choice for acrylic specialists, outperforming multi-material sets in precision and consistency.

The 20-piece Professional T-Handle Jigsaw Blade Set strikes an excellent balance between versatility and value, making it a top pick for users who regularly switch between wood, metal, and plastic—including plexiglass. With four each of T144D, T119BO, T101B, T118A, and T118B, it includes T101B blades specifically suited for clean plastic cuts, delivering surprisingly good results on acrylic up to 1/2″ thick. The high-speed steel construction resists dulling, even after repeated use on abrasive materials.

In practical use, the T101B variant produces smooth, straight cuts in plexiglass with minimal sanding needed—though tight curves require careful handling. The T-shank design locks in securely, eliminating slippage during high-speed cuts. The set excels in mixed-material workshops, from deck repairs (wood with nails) to HVAC ductwork (thin metal) and plastic enclosures. While not as refined as the Bosch PRO Plastics blade, it’s more than capable for most residential and light commercial tasks.

Compared to the 50-piece set, it offers fewer blades but better curation and quality control. Against the Romeda 10-piece, it provides greater quantity and consistency, especially for plastic and metal work. For users who want a ready-to-go, professional-grade rotation without overspending, this set delivers outstanding bang for the buck. It’s the smart middle ground between budget packs and single-purpose premium blades.
