Bosch 5-Piece 6 In. 10/14 V TPI All-Purpose Reciprocating Saw Blades

On a recent remodel, I kept reaching for one set of blades more than any other: Bosch’s all‑purpose 10/14V recip blades. After several weeks of tearing out nail-riddled framing, trimming PVC, and nibbling through thin steel and aluminum, I’ve got a clear sense of where these blades shine—and where a specialized option might serve you better.

Build and design

The Bosch all-purpose recip blades use a bi-metal body with a flexible 0.035 in thickness and a variable 10/14 TPI tooth pattern. On the bench, that design reads as “balanced”: thick and stiff enough to resist kinking under normal abuse, yet flexible enough to lay flat for flush cuts. The variable gullet spacing is a nice touch; under load, chips clear predictably, and I didn’t see the clogging you get with uniformly tight teeth when ripping through resinous wood or plastic.

The kerf is essentially the blade thickness (0.035 in), which is fairly standard for a general-purpose demo blade. It’s not razor-thin like some fine-cutting options, but that extra meat pays dividends in durability and heat absorption when you hit nails or bury the blade in wet studs.

Cutting performance in wood (with nails)

I ran the 6 in length through a mix of SPF studs, old Doug fir, and exterior trim. In clean wood, the 10/14 variable pitch tracks quickly and with less chatter than a straight 10 TPI blade. It’s not a finish-cut blade—tear-out on the exit side is expected—but it’s fast and controllable. In nail-embedded material, which is where I spent most of my time, the bi-metal teeth hold up better than many bargain blades. Hitting common nails mid-cut didn’t immediately round the teeth, and I could finish the cut without swapping blades. The blade’s flexibility let me bias pressure and steer around surprises without snapping at the tang.

If you’re doing heavy demo—say, chopping out a wall of nailed-in blocking—the 6 in length works best when you use the shoe aggressively. Keep the blade support tight and let the variable pitch do its thing. I noticed less vibration than I expected when plunging through 2x material; the front third (finer pitch) helps start cuts more controllably, then the coarser teeth take over for speed.

Plastics and PVC

For PVC and ABS, these blades strike a good compromise between speed and melting control. At a moderate stroke rate with a light touch, the gullets clear chips fast enough to minimize melting and re-welded kerfs. For cleanouts and plumbing reroutes, I could make square, flush cuts on 2 in and 3 in PVC without resorting to a dedicated plastic blade. If you run your saw on high with full shoe pressure, you’ll still get some melt; dropping the speed and letting the blade feed itself solves most of that.

Thin metals (up to 1/4 in)

Bosch rates these blades for thin metal in the 1/8–1/4 in range, and that aligns with my experience. On 1/8 in aluminum angle, cuts were smooth and relatively fast. On mild steel flat bar at 1/8 in, the 14 TPI section controls chatter, and I didn’t see the tooth-snagging you’d expect from a coarser blade. Once you push into thicker or harder stock (e.g., Schedule 80 steel pipe or anything over 1/4 in), progress slows, heat builds, and tooth wear accelerates. They will do it in a pinch, but you’ll feel like you’re using the wrong tool for the job—because you are.

Thin-wall steel conduit (EMT) is squarely in this blade’s wheelhouse. Cuts are predictable with minimal burr, especially if you ease off the trigger at the end of the stroke to avoid catching.

Flush cutting and control

At 0.035 in thick, these blades have enough flex to lay along a surface and flush-cut protruding nails, pipe stubs, and errant screws without kinking immediately. That’s a handy trait for remodeling, though it requires a practiced touch. If you lean too hard, the blade will dish and wander. Keep the shoe stabilized, use slower, shorter strokes for flush cuts, and the results are tidy.

Tracking is decent for a demolition-class blade. The variable pitch helps reduce the harmonic chatter that can yank a blade off line. For precision notches or tight curves, I’d still grab a narrower, finer blade, but for straight cuts in framing and sheet goods, this one holds a line well enough to avoid surprises behind the wall.

Durability and heat management

I judge recip blades on how long they hold a usable edge rather than how long they physically survive. Here, the bi-metal teeth hold up nicely in mixed material. I used one blade across several days of stud removal and plumbing adjustments before I noticed a meaningful drop in bite. The teeth didn’t chip out; they gradually rounded, which is what you want. Heat buildup was manageable, and the variable gullets do seem to keep chips moving. I’d still recommend a short cool-down when you’ve been leaning on the blade in metal—it extends life.

Kinking resistance is average to slightly above for this class. I had one light bend after a bad bind behind a plaster lath, but it straightened easily and kept cutting. If you’re abusive (long strokes, no shoe contact, and side loading), no blade survives for long; these buy you a bit more margin before they surrender.

Length options and pack value

I spent most of my time with the 6 in length, which is versatile for interior remodel work and tight spaces. Bosch also offers a 9 in version that’s better for deep plunge cuts or reaching around obstructions. If you routinely cut large-diameter pipe or need clearance around the saw’s shoe, the longer option is worth adding to your kit.

In a 5-pack, the per-blade cost is reasonable given the lifespan I saw. If you’re a pro doing daily demo, the 25-pack will make more sense; you’ll go through them, and it’s cheaper per piece.

What these blades are and aren’t

These are true generalists. They excel at:
- Remodeling demo: nail-embedded wood, subfloor sections, blocking.
- Service cuts: trimming PVC/ABS, nipping conduit, cutting brackets.
- Site flexibility: one blade that can stay in the saw across tasks.

They aren’t ideal for:
- Thick or hardened steel beyond 1/4 in.
- Fine-finish woodworking where splinter control is critical.
- Aggressive pruning or green wood cutting, where a hooked-tooth, low-TPI blade is faster and less likely to gum up.

Tips for best results

• In wood: Use orbital action if your saw has it and keep the shoe planted. Let the coarse section run; don’t force the cut.
• In metal: Drop the stroke rate, use minimal orbital, and don’t lean hard. A spritz of cutting fluid helps on thicker sections, but even a brief cool-down between cuts preserves teeth.
• For flush cuts: Shorten the stroke and keep the blade flat to avoid digging in. Flex is your friend, but control is everything.
• To reduce wandering: Start with the tip’s finer pitch at a lower speed, establish a kerf, then ramp up.

The competitive context

General-purpose blades live in a crowded space. Some options are faster in wood with a more aggressive tooth form, others last longer in metal with higher TPI and cobalt-rich alloys. The Bosch 10/14V blades land in the middle, which is exactly where many remodelers want to be. They offer a balanced mix of speed, control, and longevity without forcing you to swap blades every time you hit a different material.

Bottom line and recommendation

I recommend these Bosch all-purpose recip blades for anyone who does mixed-material work—especially remodelers, facility techs, and DIYers tackling renovations. They cut fast in framing, survive nails without instantly dulling, handle PVC cleanly with a light touch, and stay controllable in thin metals. The flexible 0.035 in body is forgiving for flush cuts and awkward angles, and the variable tooth/gullet design keeps chatter and clogging in check. They’re not the right choice for heavy steel or finish-sensitive carpentry, but that’s not what they’re built for. If you want one blade that can stay in the saw while you move from wood to plastic to light metal, these are a dependable, cost-effective pick.
