Festool CARVEX Splinterguard 5-Pack

Zero-clearance splinterguards custom-fit to each blade for tear-free cuts in melamine and laminates. The 5-star average rating tells the real story — contractors love these for preventing tear-out on expensive sheet goods.

Skip them if you’re just rough-cutting construction lumber. These splinterguards shine when material quality matters — cabinet shops, finish work, and anywhere a chipped edge costs you money.

The Technology That Makes Them Work

The genius is in the first cut. You insert the clear plastic guard into your jigsaw base and make your first cut with the blade. That cut creates a zero-clearance slot perfectly matched to that specific blade. No universal fit compromises. No factory tolerances. Just a custom-cut opening that supports the material right up to the blade teeth.

The splinterguards prevent tearing and fraying on the top surface by supporting the material fibers during the cut. The solid one-piece clear plastic design lets you see your cut line while providing that critical support. Think of it as a zero-clearance insert for your jigsaw — same principle as a table saw insert, but moving with the tool.

You’ll need to replace them when changing blade types since each guard is custom-cut to a specific blade width. They also wear out over time as the slot widens from use — replace when cut quality decreases. At 5 per pack, you’re looking at enough guards to handle multiple blade changes or extended production runs.

These guards fit the PS 300, PSB 300, TRION models, and CARVEX PS/PSB 400 and 420 jigsaws. That covers most of Festool’s jigsaw lineup except the newest models. The 20-pack variant (SP-PS/PSB 300/20) exists for production shops burning through guards on long runs.

Professional woodworking, precision jigsaw cutting, and delicate materials like melamine and laminates are the core applications. Montana cabinet shops working with imported melamine sheets know the pain of tear-out. These guards turn that risk into clean, sellable edges.

Users report “zero tearout” and praise the “great pointer carved into the leading edge” for accurate cuts. Another review simply states they “work great… highly recommend for your Festool jigsaw”. That pointer detail matters — it shows where your blade will cut before you start, crucial for precision work.

Don’t confuse these with track saw splinterguards — they’re not compatible. Jigsaw guards are a completely different design built for the reciprocating blade motion.

The 3-year Festool warranty covers these as wear-and-tear items. That’s unusual — most manufacturers consider splinterguards consumables with no warranty coverage. Shows confidence in the German manufacturing.

For Montana contractors dealing with limited material access and high shipping costs, reducing waste on expensive sheet goods matters more than in metro markets. One blown edge on a melamine sheet can eat your entire job profit. These guards are cheap insurance against callbacks and material replacement.

Frequently Asked Questions

Q: Which Festool jigsaws are compatible with the 490120 splinterguard?

The Festool CARVEX Splinterguard 5-Pack (model 490120) fits the PS 300, PSB 300, TRION, and CARVEX PS/PSB 400 and 420 jigsaw models. These transparent plastic guards are not compatible with track saws or other Festool tool types.

Q: How many splinterguards come in a pack and how often do they need replacement?

The Festool 490120 package includes 5 splinterguards, each weighing 0.06 lb. You’ll need to replace them when changing blade types (since each guard is custom-cut to match a specific blade width) or when the zero-clearance slot widens enough to affect cut quality.

Q: How does the zero-clearance feature work on these splinterguards?

When you insert a new Festool splinterguard into your jigsaw base and make the first cut, the blade creates a custom slot that perfectly matches that specific blade width. This zero-clearance edge prevents tearing and fraying on the top surface of materials like melamine and laminates.

Q: What’s the warranty on Festool splinterguards?

Festool covers the 490120 splinterguards under their 3-year guarantee, which includes wear-and-tear items. This German-made accessory (1.97 x 4.76 x 1.06 inches) is considered a wear item but still receives warranty coverage, unusual for consumable accessories.

Q: Is there a bulk pack option for production shops?

Festool offers the SP-PS/PSB 300/20 as a 20-pack variant of splinterguards for shops that burn through them on extended production runs. The standard 490120 5-pack works for most contractors doing cabinet work or finish carpentry.

Q: What do users say about the cutting accuracy with these guards?

Professional users report “zero tearout” with the Festool splinterguards and specifically praise the “great pointer carved into the leading edge” that shows exactly where the blade will cut. The 5-star average rating reflects their effectiveness at preventing chip-out on expensive sheet goods.
