Bosch 5" Foam Rubber Cutter Blades

Why these blades matter

Foam work lives or dies by the cut edge. Upholstery, packaging, acoustic treatment, carpet pad—if the blade chews instead of shears, the piece looks sloppy and performs worse. That’s exactly where the Bosch 5-inch foam blades (model 2607018010) earn their keep. Paired with Bosch’s 1575A foam rubber cutter, they deliver the clean, controlled shearing action I want when I’m shaping polyurethane foam cushions, trimming flexible polyethylene, or breaking down carpet pad on site.

These are not general-purpose saw blades. They’re a matched pair designed to counter-reciprocate in the 1575A, so the teeth scissor past each other rather than rip. The result is a cold cut with minimal deformation, and far less mess than a serrated knife or a jigsaw pretending to be a foam cutter.

Setup and compatibility

The blades come as a two-pack, which functions as one cutting set: both blades install together in the 1575A. Installation is straightforward—seat each blade in its clamp, align the tips, snug the screws, then run the tool briefly off the workpiece to confirm they track in parallel. If you’ve never used this type of cutter, remember that you can’t run a single blade; the tool’s cut quality depends on that opposing motion.

A note on compatibility: these blades are purpose-built for the Bosch 1575A. They don’t adapt to a jigsaw, recip saw, or other foam knives. If you don’t own the 1575A, these won’t help you.

Cutting performance

On upholstery-grade polyurethane foam (2–5 inches thick), the Bosch blades produce a crisp, square edge with very little compression. The twin-blade action keeps the foam from grabbing, so I can guide the cut with one hand and steady the work with the other. I’ve found that a steady, moderate feed rate works best—too fast and you’ll deflect soft foam, too slow and you start to polish the surface rather than slice. The sweet spot yields a surface that’s ready for adhesive or fabric without additional dressing.

With flexible plastic foams like PE and EVA, the blades shine because they cut cold. There’s no melted edge like you’d get with a hot wire on polyethylene, and far less fuzz than a utility knife. For packaging inserts, I can follow a template and get repeatable parts with clean radii. The 5-inch length is long enough for most case foam, though stacking thicker layers does push the limit.

On carpeting and carpet pad, the blades make quick, straight rips in pad and do respectable cross-cuts in low-pile carpet. Heavy, backed carpet still benefits from a hook blade for precise seams, but these blades are great for rough downsizing and for cutting pad to shape without tearing the scrim.

Accuracy and finish

These blades are agile enough to follow gentle curves. For tight radii, I angle the tool slightly and make progressive relief cuts rather than forcing a turn—foam forgives, but pushing can bruise the edge. For square edges on cushions, I keep the shoe flat and let the blades do the work; tilting the tool will bevel the edge unintentionally. When the blades are sharp, the finish is noticeably better than a serrated knife, especially on high-resilience foams that like to spring away from the cut.

If you need dead-accurate templates, light pencil or chalk lines show fine on most foams. I’ll often trace with a flexible French curve and cut just to the waste side, then make a clean pass shaving to the line. The Bosch blades are controllable enough for that finishing pass without snagging.

Durability and maintenance

Foam seems harmless, but adhesives, embedded grit, and carpet backings dull edges quickly. These blades hold up well through multiple projects, but you can feel the difference when they start to tire: the cut slows, the edge fuzzes, and you’ll see micro-tearing at the surface. At that point, don’t force it—replace the set. There’s no practical way to resharpen these paired blades to their original geometry.

A few habits extend their life:
- Avoid cutting through dried spray adhesive; score glued seams lightly and peel apart rather than plowing through.
- Keep the blades clean. A quick wipe with a rag and citrus-based cleaner removes foam dust and tacky residue.
- If you’re cutting sticky EVA, a light spritz of silicone-free dry lube on the blade sides reduces drag without contaminating surfaces for later gluing.
- Store the blades in a sleeve so the teeth don’t nick each other in a drawer.

Ergonomics and control

Because the blades counter-reciprocate, vibration at the tool is modest, which helps with line control. The 5-inch length feels like a good compromise: enough reach for common upholstery and pad thicknesses, but not so long that tip flex becomes an issue. I can see over the work, and visibility along the cut is decent. The short nose also makes plunge starts easier—start with a shallow angle and roll in, rather than jabbing straight down.

One safety note: foam dust is real, especially with urethane and carpet pad. The blades don’t create the snowstorm you get from a rasp or abrasive wheel, but I still wear a mask and eye protection. The cut is cool, but the teeth are sharp and close together; keep hands clear and respect kick when finishing a cut.

Limitations

There are two practical limits to keep in mind:
- Thickness: the 5-inch reach caps what you can do in a single pass. For 6-inch-plus upholstery foam, I cut from both sides or step-cut. It works, but a longer blade set would be more efficient for deep stock.
- Material scope: these are optimized for foam and pad. They’ll cut low-pile carpet, but they’re not seam-finish blades. For dense rubber or materials with embedded grit, you’ll reduce blade life quickly.

I also wish there were more length options readily available. The 5-inch set covers most of my needs, yet having a longer pair for deep cushions and a shorter set for tight template work would round out the system.

Value and use cases

For anyone already invested in the 1575A, this two-blade set is a staple consumable. One pack gets me through a surprising amount of work, especially if I’m mindful about adhesive and grit. The time saved compared to knife-cutting cushions or struggling with a jigsaw is significant. Edges come off the tool clean enough to glue or upholster immediately, which shortens build time and reduces rework.

Typical jobs where these blades pay off:
- Shaping seat and back cushions with square, consistent edges
- Trimming carpet pad to contour without tearing
- Cutting case foam (PE/EVA) to templates for tools or electronics
- Sizing acoustic foam panels and bass trap fills

Tips for best results

• Mark clearly and support the offcut. Foam tears when it’s allowed to fall away during the last inch.
• Let the blades find the line. Pushing hard deflects foam and introduces bevel.
• Make shallow relief cuts for tight curves instead of forcing a single sweeping turn.
• Keep adhesive away from the cut path whenever possible; glue shortens blade life.
• Replace the set at the first sign of fuzzed edges—sharp blades are safer and cleaner.

Recommendation

I recommend the Bosch 5-inch foam blades for anyone using the 1575A to cut upholstery foam, carpet pad, or flexible plastic foams. They produce clean, square cuts with good control, they last respectably if you avoid adhesives and grit, and the two-pack format ensures you have a working pair ready to go. The 5-inch length covers most everyday tasks, and the cold-cut action avoids the melting and mess that plague other methods on flexible foams. The main caveats are the reach limit on very thick stock and the single-tool compatibility, but within their intended use, these blades are efficient and reliable consumables that elevate the quality of foam work.
