CONNOO 156 Pack Oscillating Saw Blades, Oscillating Tool Blades with Sandpaper, Multitool Bi-Metal Blades Kits for Wood Metal Plastics Quick Release Fit Dewalt Ryobi Milwaukee Rockwell Makita

I measure oscillating-tool accessories by three things: fit, cut quality, and lifespan. After a few weeks using the CONNOO 156-piece blade kit on a mix of trim work, flooring prep, light plumbing, and paint removal, I’m convinced it hits a sweet spot for general-purpose jobsite and DIY use. It’s not a boutique set of specialty blades; it’s a broad, affordable arsenal that covers most tasks you throw at a multitool without flinching.

What’s in the kit

This kit bundles a wide range of oscillating blades and sanding consumables. You get high‑carbon steel (HCS) wood and plastic blades, bi‑metal blades for metal and embedded fasteners, rigid scrapers, and a selection of sanding sheets with a hook‑and‑loop pad. Many blades carry a precision “wavy-tooth” profile and depth markers etched in both inches and centimeters. Everything uses a universal quick‑release interface designed to fit the common OIS-style patterns.

I appreciate that each blade arrives individually packaged. It’s a small detail, but it prevents teeth from dinging each other in transit and keeps the coating from rubbing off before you even start cutting.

Build and design

The blades are forged from HCS and stainless steel, then coated in a heat-resistant black finish. In practice, the coating is helpful for corrosion resistance and initial heat shedding; it does wear off quickly at the toothline—as expected—without affecting cut quality. Tooth geometry on the wood blades leans aggressive but controllable, and the bi‑metal offerings use a finer pitch suitable for thin metals.

Sizing and readability are better than I anticipated at this price. The dual-scale depth markings are clear and durable, and I found them genuinely useful when undercutting door jambs or matching plunge depths across multiple cuts.

Fit and tool compatibility

Fit was solid on every OIS-style tool I tried. The blades locked up cleanly on a DeWalt XR, Milwaukee M18 oscillating multi-tool, Makita XMT series, and a Ryobi ONE+ brushless model. Using the included C‑adapter, I also ran blades on a Dremel Multi‑Max 6300 with no slop or wandering in the cut.

Important caveats:
- Not compatible with Starlock systems (Fein Starlock, Bosch Starlock, Makita DTM52) or certain proprietary quick‑release noses.
- Some older Bosch and Dremel “quick release” models, and Bosch MX30, are not supported.
- Rockwell and Worx tools may require an adapter (not always included).

One note from my bench time: the sanding pad fit the DeWalt and Milwaukee perfectly, but on an older Ryobi body it didn’t index quite as positively as the blades. It still worked, but it took an extra moment to seat it square. That’s a minor quirk to be aware of if you’re mixing older and newer tool heads.

Wood cutting performance

If you spend most of your oscillating-tool time in wood, this kit makes a strong case for itself. The wavy-tooth HCS blades are quick and fairly clean in pine, poplar, and MDF. I trimmed door casing for LVP installs, notched baseboard for electrical retrofits, and flush-cut a handful of shims and pocket screws. The blades tracked well with minimal chatter, even when I had to reach awkwardly around a jamb.

In hardwoods like red oak, the HCS blades still cut acceptably, but they lose their edge faster—no surprise there. Switching to a bi‑metal for hardwood with possible fasteners gave me better longevity. The narrower plunge blades are particularly handy for tight cutouts and reduce the “wedging” effect that can cause wandering.

Depth control via the etched markings is more than cosmetic. On repetitive undercuts, it kept my blade motion consistent and saved me from overcutting into backer materials. Tear-out was modest; easing into cuts and letting the blade do the work produced the best edges.

Metal, plastics, and odd jobs

The bi‑metal blades handled copper and thin-wall conduit cleanly and were fine for trimming an errant screw or nail. They are not magic against hardened fasteners—no bi‑metal at this price is—but for thin steel and non-ferrous materials they work as intended. Expect sparks on steel and pace your cuts to avoid overheating. When I pushed too hard on a stubborn screw, I dulled a tooth row quickly; slowing down gave me far better life.

PVC and ABS cuts were straightforward. The coarser tooth HCS blades stay cooler in plastic; the finer bi‑metal can generate heat and melting if you rush. Back off the oscillation rate and feather the plunge to keep edges clean.

For surface prep, the rigid scraper blade was surprisingly effective on paint drips and adhesive residue. If your kit includes a grit-coated segment blade, it’s useful for grout touch-ups and light mortar cleanup, though I wouldn’t choose it for extensive tile demo. Carbide-grit accessories in value kits typically trade speed for versatility; that’s the case here.

Sanding and surface prep

The hook‑and‑loop sanding pad is serviceable for corners and edge touch-ups. It won’t replace a dedicated detail sander for larger areas, but it’s perfect for knocking down filled nail holes, scuffing trim before paint, or cleaning up a patched drywall corner. The included paper assortment covers common grits. The pad’s backing held up to moderate use without shedding the velcro, and heat buildup was manageable if I kept the speed down and moved frequently.

Durability and blade life

No blade is immortal, and oscillating accessories are consumables—especially in the budget tier. Within that context, the life I got was solid. The HCS wood blades stayed sharp across multiple door jamb undercuts and assorted trim cuts. Hitting hidden nails predictably chewed them up; swapping to bi‑metal before suspect cuts saved me grief. The bi‑metal blades lasted through several metal tasks apiece, provided I didn’t force the cut or overheat them.

Two practical tips that improved longevity:
- Let the blade do the work. Slowing the oscillation speed in dense materials keeps teeth cooler and sharper, longer.
- Use the right blade for the job. Reserve bi‑metal for nails and metals; keep HCS for clean wood and plastics.

Everyday usability

What makes this kit easy to live with is how quickly I can grab a blade for a task and not worry about rationing “the good ones.” The quick‑release pattern locked consistently, the back-of-blade markings stayed readable after use, and the variety meant I always had a width and tooth profile that fit the cut.

My only usability knock is organization. The blades come individually bagged rather than in a dedicated case. That’s fine out of the box, but it’s worth investing in a small parts organizer so you’re not fishing through a pile when you’re mid-project.

Value

This is where the CONNOO kit shines. The per-blade cost is a fraction of what you’ll pay for single OEM blades at a big-box store. For tasks that inherently punish blades—demo, rough-in, cutting close to masonry—value matters more than squeezing the last ounce of life from a premium accessory. I’d still keep a couple of high-end specialty blades on hand for heavy metal or precision finish work, but for 90% of what most people do with a multitool, this kit carries the day.

Who it’s for

• DIYers and homeowners who want a ready-to-go assortment for repairs, flooring, and trim work.
• Remodelers who burn through blades during demo and need volume without a big bill.
• Pros who keep value blades for rough tasks, saving premium blades for critical cuts.

If you run a Starlock tool exclusively or rely on a proprietary quick‑release that’s not supported, this set isn’t for you. Likewise, if your daily workload is heavy metal cutting, you’ll want a stash of premium bi‑metal or carbide-tooth blades alongside this kit.

Recommendation

I recommend the CONNOO 156-piece blade kit. It offers broad compatibility with common OIS-style tools, practical cut quality across wood, plastics, and light metal, and genuinely useful features like dual-scale depth markings—all at a price that makes frequent blade swaps painless. Aside from the lack of a storage case and some expected limits around specialty tool interfaces, it delivers exactly what a multitool blade bundle should: lots of usable options, decent lifespan, and dependable fit. For general carpentry, renovation, and household projects, it’s an easy add to the toolbox.
