Oscillating multi tool blades are the first thing I reach for when I crack open a wall and realize the framing isn’t going to cooperate. A recip saw can be fast, but it’s often too bulky for clean cuts near pipes and nails. In this post I’ll show how I use Spyder oscillating multi tool blades to work faster in tight spaces—and leave less mess behind.

Quick takeaway: In wall cavities, I want control. The oscillating multi-tool gives me that control—but only if I’m running the right oscillating multi tool blades.

Why oscillating multi tool blades matter when you open a wall

If you’re a contractor, homeowner, or DIYer, you already know how this goes: you open the wall for a “simple” plumbing change… and suddenly the framing is in the way. Blocking, studs, old repairs, random fasteners—there’s always something holding you up.

In that moment, the fastest path forward is usually the same: remove what’s in the way so you can rebuild clean and run the plumbing where it needs to go.

That’s exactly why I keep a multi-tool close. If you’re newer to building out a practical tool kit, this is one of those “you’ll thank yourself later” tools—here’s my broader list of essentials: What tools do I need? (10 must-have power tools for beginners).

Oscillating multi tool blades vs recip saw in tight spaces

I’ll be honest: back in the day, I reached for a reciprocating saw first. It’s fast, it’s familiar, and for a long time it felt like there were more blade choices—especially if you needed to cut wood with nails.

But here’s the problem: once you’re working inside a wall cavity, the recip saw can turn into a liability. It’s not that the tool is bad. It’s that the space is tight and the cut needs to be controlled.

Why the recip saw can be the wrong move inside a wall

  • It can be too big to fit. You can’t always get the shoe and body where you need them.
  • It’s aggressive. That stroke is great in open demo, but it can punish you near wires, pipes, and drywall.
  • Collateral damage happens fast. One slip and you’ve got more repair work than you planned.

When the space is tight, I want a tool that lets me “nibble” my way through the cut with precision. That’s where the oscillating multi-tool wins—and why the oscillating multi tool blades you choose matter so much.

Still love your recip saw? Same. I’m not throwing it away. I just use it where it shines (open access, long reach, heavy demo). If you want to sharpen your blade selection strategy for that tool, read: Reciprocating saw blades: the complete guide (TPI, lengths, ROI & safety).

What changed: blade options finally caught up

Here’s the big shift I’ve seen on jobsites: a lot of “old timers” didn’t view the oscillating multi-tool as a real solution. The first time I brought one onto a job years ago, I got the classic reaction—“What is that thing? It makes too much noise. Get rid of it.”

And honestly? Some of that skepticism made sense back then. The blade selection wasn’t great. If you didn’t have the right oscillating multi tool blades for the material you were cutting, the tool felt slow and pointless.

That’s not the case anymore. Now there are blade options for wood, nails, screws, PVC, drywall, and metal. Once the blade selection improved, the oscillating multi-tool stopped being a “gadget” and turned into one of the first tools I grab.

Spyder oscillating multi tool blades: what’s in the 5‑piece bi‑metal set

For this kind of “open wall / make room / rebuild clean” work, I like a mixed pack that covers multiple materials. A solid example is the Spyder 5‑piece bi‑metal oscillating multi tool blades set.

Official specs (worth bookmarking): Spyder 5‑piece bi‑metal oscillating tool blade set (SKU 70000)

What’s inside the 5‑piece Spyder oscillating multi tool blades pack?

This set is designed to cover the stuff you actually hit in remodel work:

  • Wood + nails blades (multiple sizes for reach and speed)
  • Clean wood blade (for nicer, cleaner cuts)
  • Metal blade (for track, studs, and fasteners)

Why the “materials” list matters

I’m looking for blades that don’t fold the moment they meet a nail. Spyder positions these as 8% cobalt bi‑metal with dual/tri-plated teeth to reduce friction and heat, plus laser-engraved depth markings and a full 2" depth of cut on each blade (per Spyder’s product details).

How I choose oscillating multi tool blades by material

If you want oscillating multi tool blades to feel “fast,” you have to match the blade to what you’re cutting. Here’s my simple cheat sheet.

Oscillating multi tool blades cheat sheet

  • Clean wood: trim work, clean plunge cuts, less tearout
  • Wood with nails: remodel framing, blocking removal, nail-infested lumber
  • Metal: metal studs, track, screws/fasteners, straps
  • PVC / drywall: controlled openings and access cuts

My rule: if there’s even a chance I’ll hit nails, I don’t “gamble” with a clean wood blade. I start with a wood-with-nails (bi‑metal) blade and keep moving.

Step‑by‑step: using oscillating multi tool blades inside a wall cavity

This is the workflow I use when I’m making framing alterations for plumbing (or any wall-cavity fix). I’m keeping it practical—not theoretical.

1) Confirm what’s behind the cut

Before I do any plunge cutting, I assume there could be wires, pipes, or old fasteners hiding where I can’t see them. If you’re not sure, stop and verify. This is where patience saves expensive mistakes.

2) Mark your “do not exceed” depth

Depth markings are one of those small features that make a big difference. I’ll literally pick a line and treat it like a hard limit—especially if a pipe is nearby.

3) Choose the blade for the reality of the wall

  • If I expect nails: wood + nails blade.
  • If it’s clean framing: clean wood blade.
  • If it’s metal framing: metal blade.

4) Cut in stages (don’t try to “one-pass” everything)

I start shallow, get the blade tracking, then work deeper. In tight spaces, I’m not chasing speed—I’m chasing control. Speed shows up naturally when the tool isn’t fighting you.

5) Remove the member clean and rebuild intentionally

Once the blocking or section is out, I clean up the opening and rebuild framing so the plumbing has proper space and support. If you’re dealing with load-bearing framing, don’t guess—follow code and get the right guidance.

Wood with nails: how I cut nails fast without trashing blades

This is the moment that sold a lot of people (including me): you open the wall and realize the “easy drill-through” plan is dead because there are nails everywhere. That’s when oscillating multi tool blades designed for wood-with-nails pay for themselves.

What I’m trying to avoid

  • Cooking the blade with too much pressure
  • Binding the blade and bending teeth
  • Destroying a “clean wood” blade by slamming into nails

How I approach nail-infested lumber

  1. Use a wood-with-nails blade and let the teeth do the work.
  2. Work from multiple angles if needed instead of forcing a single line.
  3. Keep the tool moving—heat kills blade life.

Reality check: If you’ve ever tried to dissect two nailed-together pieces of wood with a recip saw in a cramped cavity, you already know why the oscillating multi-tool becomes the go-to here.

Metal studs & track: oscillating multi tool blades in confined spaces

Sometimes you open the wall and it’s metal studs or track. And yes—someone will always say, “Just use snips.”

My response is simple: if you can fit snips in there, go for it. But in a confined space (tight cavity, awkward angle, limited swing), snips aren’t always practical.

My technique for cutting metal track with oscillating multi tool blades

  • Use the metal blade (don’t force a wood blade through steel).
  • Light pressure—pushing harder often cuts slower and overheats teeth.
  • Short passes to manage heat and keep the cut straight.

For a freehand cut in a cramped spot, a good metal-capable oscillating blade can do a surprisingly clean job—without turning the cavity into a mess.

Pro tips: make oscillating multi tool blades cut faster and last longer

Most “slow blade” complaints come from technique, not the tool. Here are the habits that keep my oscillating multi tool blades working like they should.

1) Don’t push—guide

The oscillating multi-tool isn’t a recip saw. If you’re leaning into it like a demolition tool, you’ll generate heat, dull teeth faster, and make the cut feel worse.

2) Keep the cut moving

If the blade sits in one spot, friction climbs and performance drops. A steady, controlled motion helps clear material and keeps the teeth biting.

3) Don’t pry with the blade

I never use the blade as a lever. If the piece needs persuasion, I grab a different tool. Prying is how you bend blades and destroy teeth.

4) Carry a small “wall-cavity blade kit”

  • One clean wood blade
  • Two wood-with-nails blades
  • One metal blade

Compatibility: will Spyder oscillating multi tool blades fit your tool?

This is a huge deal—because “almost fits” is basically “doesn’t fit” on a jobsite.

Universal-fit oscillating multi tool blades (open-back tools)

Spyder positions this set as a universal fit arbor compatible with open-back oscillating tools (and includes an adapter for Dremel).

Heads up on Starlock: These blades are not compatible with Starlock tools. If your tool is Starlock-only, you’ll need Starlock-compatible blades.

Safety checklist for oscillating multi tool blades (especially in walls)

I’m going to keep this short and serious. Cutting in walls is where hidden hazards live.

  • Wear eye protection. Small chips and metal slivers move fast.
  • Assume something is hidden. Check for wires, gas pipes, and water pipes before blind cuts.
  • Control dust. Use a mask when needed and keep the area clean.
  • Power down for blade changes. Battery out / unplug before swapping.

FAQ: oscillating multi tool blades

Are oscillating multi tool blades universal?

Some are “universal fit” for open-back tools, but not all systems are the same (Starlock tools can require Starlock-compatible blades). Always confirm your tool’s interface before buying.

What are oscillating multi tool blades used for?

I use oscillating multi tool blades for plunge cuts, flush cuts, trimming in tight spaces, and controlled removal of wood, nails, PVC, drywall, and even some metal—especially in wall cavities and remodel work.

Can an oscillating multi-tool cut nails and screws?

Yes—with the right blade. A bi-metal wood-with-nails blade is made for that “hidden fastener” reality in remodel framing.

What’s the best oscillating multi tool blade for wood with nails?

In my experience, a quality bi-metal blade designed specifically for wood-with-nails is the safe bet. That’s where sets like the Spyder mixed pack make sense because you’re not guessing.

Can oscillating multi tool blades cut metal studs and track?

Yes. A dedicated metal blade can handle thin-gauge studs and track—especially when snips won’t fit and you need a controlled cut.

Why won’t my oscillating multi tool blades fit my tool?

The two common reasons are (1) your tool uses a different mounting system (like Starlock-only), or (2) you need an adapter (some brands/models require one). Verify before you buy.

How long do oscillating multi tool blades last?

It depends on the material, heat, and pressure. If you keep the blade moving, use the right tooth geometry for the job, and avoid overheating, you’ll get significantly more life than if you force the cut.

How do you change an oscillating multi tool blade safely?

Power down fully (battery out/unplug), let the blade cool, then swap. Blades can be sharp enough to cut you even when they “look harmless.”

Final thought

If you’re making alterations inside a wall cavity, I genuinely think the oscillating multi-tool is one of the smartest “first grabs” you can make—as long as you’re using the right oscillating multi tool blades.

So let me ask you the same question I ask everyone: do you still reach for the recip saw first, or are you choosing the oscillating multi-tool instead?
