Types of Oscillating Tool Blades and Their Uses
Oscillating tool blade types and their uses: high-carbon steel, titanium-coated, bi-metal, Japanese tooth and scraper blades, what each one cuts, and the kits that cover the jobs.
On this page
A doorway that needs trimming, a patch of drywall to open, a nail buried in old framing: the job changes from cut to cut, and the blade has to change with it. Types of oscillating tool blades differ by tooth shape, material and edge, and each type suits some materials and struggles with others. This guide names the common types, what each one cuts, and which kit covers the jobs in a home garage.

Types of oscillating tool blades and what each one cuts
The blade types below all come from the kits in this guide. Tooth shape decides how fast a blade moves through a material, the blade material decides what it can touch without dulling, and the edge shape decides how clean the entry feels.
| Blade type | Cuts | Watch for |
|---|---|---|
| High-carbon steel (HCS) | Wood, drywall, plastic and general purpose cuts | Keep it off nail-embedded wood and metal |
| Titanium-coated | Wood with nails, copper pipe, thin-gauge metal and aluminum | Listed for heat resistance and longer life |
| Bi-metal | Wood with nails and soft metal | Reach for it where nails hide in the wood; for clean wood, the Japanese tooth blades are the faster pick |
| CrV Japanese tooth | Hardwood, softwood, drywall and PVC, with fast cuts | Reach for these first when wood and drywall are the main materials |
| Arc-edge semi-circular | Smoother material entry on curved cuts | Not a plunge blade for deep stock |
| Scraper | Paint, caulk and adhesive removal | Scrapes, does not cut |
| Sanding pads and sandpaper | Surface prep, from coarse stock removal to fine finish | Hook-and-loop backing, so sheets swap fast |
Only the LEILUO kit here mixes several of these types; the other three sets are single-type titanium, so pick the kit whose blades match the materials in the job list, then keep the right tooth for each cut.
How to match a blade to the material
Start with the material. Plain wood, drywall and plastic take a high-carbon steel blade or a CrV Japanese tooth blade, which the maker lists for faster wood cuts with less tear-out. Wood with nails, copper pipe, thin-gauge metal and aluminum call for a titanium-coated blade or a bi-metal blade, since plain high-carbon steel dulls fast on metal.
Then check the depth. Standard blades run 34-40mm, which suits shallow cuts and trim. A 70mm extra-long blade clears thick stock in a single plunge, such as 2x4s, door frames and stacked flooring, and reaches into tight spaces where a short blade cannot finish the cut. The AMZWEI set lists a 2-3/4 inch cutting depth with its 70mm blades, and the maker claims 2x cutting efficiency from the extra reach.
Tooth shape matters too. Japanese teeth cut faster than standard tooth blades, per the AMZWEI listing, and a curved edge adds stability during the cut. Length markers in inches and metric, printed on both sides of the Bionso blades, help keep plunge depth consistent.
Fit comes last. Universal interfaces are listed for 95%+ of oscillating tools, and the AMZWEI set includes 3 clip adapters for Dewalt, Bosch, Milwaukee and Ryobi. Exceptions matter: the LEILUO kit is not compatible with star.lock, star.lock plus or star.lock Max tools, and Dremel tools need the adapter included in the box.

FAQ: garage tools
What is the difference between HCS and titanium-coated oscillating blades?
High-carbon steel blades suit general purpose cuts in wood, drywall and plastic. Titanium-coated blades add heat resistance and longer life, per the makers, and suit nail-embedded wood, copper pipe, thin-gauge metal and aluminum. Use HCS where the material is clean, and titanium-coated where metal hides in the cut.
Can one oscillating blade cut wood and metal?
Yes, with the right type. Bi-metal blades are listed for wood with nails and soft metal, and titanium-coated blades are listed for wood with nails, metal and plastic. A plain high-carbon steel blade is the wrong pick for metal, since it dulls fast on hard material.
What does a 70mm blade do that a standard blade cannot?
A 70mm blade clears thick stock in a single plunge, such as 2x4s, door frames and stacked flooring, while standard 34-40mm blades suit shallow cuts. The extra reach also helps in tight spaces where a short blade cannot finish the cut.
Do these blades fit any oscillating tool?
Most of them. Universal interfaces are listed for 95%+ of oscillating tools, and the AMZWEI set includes 3 clip adapters. Exceptions matter: the LEILUO kit does not fit star.lock, star.lock plus or star.lock Max tools, and Dremel tools need the adapter included in the LEILUO box.
How many blades come in these kits?
The kits here hold 35, 20, 158 and 26 pieces. The 158-piece LEILUO kit also adds scraper blades, sanding pads and sandpaper, while the smaller kits stick to cutting blades.
