Intro
When you pick up an oscillating multi-tool, you are holding one of the most versatile power tools ever made. It can cut through wood, slice through metal, scrape off old adhesive, remove grout between tiles, and even sand tight corners — all with a simple back-and-forth motion. But here is the catch: the tool itself is only as good as the blade you attach to it. A cheap, dull blade turns even the best multi-tool into a loud, vibrating paperweight that barely scratches the surface. Whether you are a professional tradesperson who relies on these tools every day or a dedicated DIY enthusiast tackling weekend projects, having the right set of blades and accessories makes all the difference. From plunge cutting into floorboards to trimming door jambs during flooring installation, from stripping paint off window frames to removing tile grout in a bathroom renovation — each job demands a specific blade type, and having them all within reach saves time, frustration, and money.
Generalities
Oscillating multi-tools have become essential in construction, renovation, and home improvement, but their real value comes from the blades and accessories you pair them with. Before buying a blade set, there are a few things worth thinking about. First, material matters — bi-metal blades made from alloy steel cut faster and last far longer than standard high-carbon steel, especially when you are working with nails, screws, or hardwoods. Second, compatibility is key — some kits use a universal mounting system that fits most major brands (Bosch, Makita, DeWalt, Fein), while others lock you into one brand. Third, variety counts: a good kit should include plunge cut blades, segment saw blades, scrapers, sanding pads, and a grout removal tool so you are ready for any task. CMT Orange Tools, an Italian brand with a strong reputation in precision cutting tools and woodworking accessories, brings its engineering expertise to this category with a kit designed for both professionals and serious home users.
This review takes a close look at a 37-piece oscillating multi-tool blade and accessory set from CMT. We will examine what comes in the box, how well the blades perform on different materials, whether the universal fitting works reliably with popular tool brands, and how the overall value stacks up. We will also cover the storage and organisation, the build quality of the accessories, and which real-world jobs this set handles best — so you can decide if it is the right kit for your toolbox.
Description
At the heart of this kit are 37 individual pieces built for the demanding stop-start cutting action of an oscillating multi-tool. The blades are made from alloy steel, a step up from the basic high-carbon steel found in budget sets, which means they hold an edge longer and resist heat build-up during extended use. The set includes bi-metal plunge cut blades in multiple widths for cutting wood, plastic, and non-ferrous metals, along with segment saw blades designed for deep, aggressive cuts. A carbide-grit blade handles grout removal and light masonry work, while rigid and flexible scraper blades tackle everything from stubborn adhesive to soft caulk. Rounding out the cutting tools are a Japanese-tooth blade for fast wood cutting and a flush-cut blade for trimming in tight spaces. The kit also includes a hook-and-loop sanding pad, multiple sandpaper sheets in different grits, and an adapter ring to ensure compatibility across tool brands.
What sets this CMT kit apart from generic alternatives is the attention to build quality. The alloy steel blades are laser-cut and heat-treated, producing clean, precise edges that translate to smoother cuts with less vibration. The universal mounting system uses a star-pattern interface that fits most popular oscillating multi-tools — including models from Bosch (Starlock-compatible with the included adapter), Makita, DeWalt, Fein, Ryobi, and Einhell — without needing separate adapters for each blade. This is a practical detail that saves time on the job site, as you can swap between tasks without hunting for the right fitting. The orange colour coding on the blades, a signature CMT design touch, also makes it easy to identify blade types at a glance inside the case. The sanding pad uses a standard hook-and-loop system, so you can use third-party sandpaper sheets when the included ones run out.
Ease of use is where this kit shines during real-world testing. Blade changes are quick — the universal mounting pattern aligns with the tool's spindle, and the retaining bolt tightens down securely without slipping. The bi-metal plunge cut blades slice through 18 mm plywood and softwood with minimal burning, and they handle PVC pipe and aluminium trim cleanly. The scraper blades feel rigid where they need to be — the stiff scraper removes linoleum adhesive and carpet glue without flexing or chattering, while the flexible version follows contoured surfaces when removing silicone sealant. The carbide-grit grout blade bites into tile grout effectively without excessive wander, though it works best at lower oscillation speeds to avoid glazing the grit. The sanding pad attaches firmly and the included sandpaper sheets range from coarse 60-grit for aggressive material removal to fine 240-grit for finishing, giving you a complete surface-prep solution in one kit.
Beyond the blades themselves, the accessories and extras in this kit add meaningful value. The sanding pad is shaped to fit the oscillating tool's triangular footprint, reaching into corners that a random-orbit sander cannot touch. The assortment of sandpaper grits means you can go from rough shaping to finish-ready surfaces without buying separate packs. The rigid scraper includes a sharpened edge that bites into paint drips and dried construction adhesive, while the flexible scraper handles delicate jobs like removing stickers from glass or lifting old window glazing putty. A plastic storage case keeps everything organised — each blade has a labelled slot so you can see at a glance what is missing. The case is compact enough to fit in a tool cabinet drawer or a site bag, yet sturdy enough to protect the blades during transport.
The kit is lightweight and portable — the entire set weighs less than 2 kg including the storage case — making it easy to carry between job sites or store on a shelf. CMT Orange Tools stands behind this product with its reputation for quality manufacturing, and the alloy steel construction means you are investing in blades that outlast budget alternatives by a wide margin. Customer feedback supports this: the set holds a rating of 4.7 out of 5 stars from verified buyers, who consistently praise the value for money and the range of blades included. While it ranks at #1,116 in Oscillating Tool Accessories on its category page, the small number of reviews suggests this is an under-the-radar gem rather than a mass-market product — a common story with specialist Italian tool brands that prioritise quality over marketing volume.
Pros and cons
Pros
- Alloy steel blade construction delivers longer edge life and higher heat resistance than standard high-carbon steel blades found in cheaper kits.
- Comprehensive 37-piece selection covers virtually every oscillating multi-tool task — plunge cutting, segment sawing, scraping, grout removal, and sanding — all in one case.
- Universal star-pattern mounting system with included adapter makes the kit compatible with most major brands including Bosch, Makita, DeWalt, Fein, and Ryobi.
- CMT Orange Tools is a respected Italian manufacturer with decades of precision cutting tool expertise — this is not a no-name generic import.
- The sanding pad and multi-grit sandpaper assortment (60 to 240 grit) turns your oscillating tool into an effective detail sander for corners and edges.
- Labelled storage case keeps all 37 pieces organised, making it easy to spot a missing blade and protecting the cutting edges during transport.
- Excellent value at this price point — buying individual branded blades for each task would cost two to three times as much.
- Orange colour-coded blades allow quick visual identification of blade types, a small but genuinely useful detail on a busy work site.
Cons
- The sandpaper sheets are a consumable — once they wear out, you will need to buy replacements, and the triangular shape is slightly harder to find than standard rectangular sandpaper.
- While compatible with most brands, the universal mounting system does not support the newer Starlock Max interface used on some high-end Bosch and Fein tools without an additional adapter.
- The plastic storage case, while functional and well-labelled, feels less premium than the metal or reinforced cases included with some professional-grade kits.
- Limited user reviews (only 4 at the time of writing) mean there is less long-term community feedback available compared to more widely distributed brands.
- The carbide-grit grout blade works well at lower speeds but can glaze over if run at maximum oscillation — a learning curve for users unfamiliar with this type of blade.
Use cases
This kit is ideal for DIY renovators, professional carpenters, flooring installers, and general contractors who need a comprehensive set of high-quality oscillating multi-tool blades for cutting, scraping, sanding, and grout removal across a wide range of materials and job types.
Flooring Installation and Door Jamb Trimming
The plunge cut blades in this kit are purpose-built for undercutting door jambs and architraves during laminate, vinyl, or hardwood flooring installation. The bi-metal teeth cut through wood and any hidden nails cleanly, leaving a neat recess for the new flooring to slide under. The flush-cut blade is perfect for trimming off protruding floorboards or cutting skirting boards without damaging adjacent surfaces.
Grout Removal and Bathroom Renovation
With the carbide-grit grout removal blade and the flexible scraper, tackling a tired bathroom becomes much faster. The grout blade digs into old, cracked grout between tiles without excessive wandering, while the flexible scraper peels away silicone sealant around the bathtub and sink. The sanding pad then smooths out rough edges before re-grouting and re-sealing.
Paint and Adhesive Stripping
The rigid scraper blade makes short work of paint drips, dried construction adhesive, and old linoleum glue on subfloors. For more delicate surfaces, the flexible scraper lifts stickers, decals, and window film without scratching the glass or painted surface underneath. Combined with the sanding assortment, you can go from stripped to smooth in a single session.
General DIY and Home Repairs
For the weekend DIYer, this kit covers an enormous range of jobs. Cutting out a section of drywall to access wiring or plumbing becomes precise and dust-controlled. Trimming plastic pipe during a sink replacement is clean and fast. Removing old window putty before re-glazing is straightforward with the flexible scraper. Having all 37 pieces in one organised case means you reach for the right blade instead of improvising with the wrong tool.
Professional Carpentry and Fit-Out Work
Carpenters and kitchen fitters will appreciate the alloy steel build quality that stands up to daily use. The bi-metal blades stay sharp through repeated cuts in hardwood, MDF, and laminate-faced panels. The precise laser-cut edges produce clean cuts that need less sanding afterwards — a time-saver on paid jobs. The labelled case makes it easy to check that all blades are accounted for at the end of a day on site.
