Arrow OSC107-10 Review

Tackling home improvement projects often means working in awkward spots where standard saws simply cannot reach. Whether you are cutting through skirting boards already fixed to the wall, trimming door frames flush with the floor, or making precise cutouts in plasterboard for electrical boxes, the right cutting accessory makes all the difference between a clean professional finish and a frustrating, messy job. Oscillating multi-tool blades have become a staple in the toolkit of DIY enthusiasts and tradespeople alike because they can slice, scrape, and plunge-cut in confined spaces where other tools would struggle. From hardwood and softwood to PVC piping, copper tubing, and even drywall, a good set of blades transforms your oscillating multi-tool into a truly versatile cutting machine. But not all blades are created equal — material quality, tooth design, and compatibility all play a huge role in how quickly and cleanly you get the job done.

When shopping for oscillating multi-tool blades, the first thing to look at is the material. Standard high-carbon steel blades are cheap but dull quickly, especially when you hit a hidden nail or screw. Bimetal blades, which combine a flexible spring-steel body with a hardened high-speed steel cutting edge, offer dramatically better durability and heat resistance. Compatibility is another key factor — most modern blades feature a universal open-back fitting that works with the major brands like Dremel, Milwaukee, DeWalt, Bosch, and Makita, but it is always worth double-checking before you buy. Tooth pattern matters too: alternating-tooth designs with deep gullets clear debris faster and cut more smoothly than straight-tooth blades, especially in materials prone to clogging like softwood or PVC.

In this review we take a close look at a 10-piece set of standard bimetal oscillating blades from Arrow Fastener, a brand known in the fastening and cutting tool space. We cover material quality, cutting performance across different surfaces, compatibility with popular multi-tool brands, and overall value for money — so you can decide whether this set deserves a spot in your toolbox.

At the heart of the Arrow OSC107-10 set are ten bimetal oscillating blades, each measuring 33 mm (1-5/16 inch) in width. The bimetal construction pairs a tough, flexible steel body with a hardened high-speed steel cutting edge, giving you the best of both worlds: the blade bends under pressure instead of snapping, while the teeth stay sharp far longer than standard carbon-steel alternatives. Arrow claims these blades last up to 15 times longer than comparable high-carbon steel blades — a bold figure backed by the inherent durability of bimetal technology. The ETS (Every Tooth Set) pattern features teeth that are alternately offset left and right, creating a kerf slightly wider than the blade body for fast, clog-free cutting.

Design-wise, several thoughtful touches stand out. The universal open-back mounting system means these blades click straight onto the vast majority of oscillating multi-tools on the market — no adapters or fiddly adjustments needed. The blue and brass colour scheme is not just for looks; the brass-toned cutting edge visually distinguishes the hardened tooth section from the flexible steel body. Each blade is precisely stamped for consistent geometry across the entire 10-piece pack, so you get the same cutting experience from the first blade to the last.

In everyday use, these blades shine in tight, awkward spaces where a traditional saw would be useless. The 33 mm width is compact enough to squeeze between floorboards or into corners, yet broad enough to make meaningful progress on wider cuts. The ETS tooth pattern clears sawdust efficiently, reducing heat build-up and keeping the cut line visible. Whether you are flush-cutting a door jamb to fit new flooring, slicing through PVC waste pipe under a sink, or making plunge cuts in plasterboard for a new socket box, the blade tracks predictably and leaves a reasonably clean edge — though fine finishing may still require a light sand on visible surfaces.

The 10-piece pack size is a practical choice for both occasional DIYers and regular users. Having multiple blades on hand means you can swap to a fresh one the moment cutting speed drops, without having to stop mid-project and order more. These blades tackle a versatile range of materials: wood (including wood with embedded nails), PVC, copper tubing, and drywall. The packaging is straightforward — ten blades in a single pack with no bulky storage case, keeping costs down and making it easy to drop a few spares into your tool bag.

Physically the pack measures 12.7 × 20.3 × 20.3 cm and weighs just 237 g, making it lightweight and easy to store. Arrow Fastener — a brand with decades of experience in fastening tools — manufactures these blades. The product holds a perfect 5.0 out of 5 stars rating based on 2 customer reviews at the time of writing, and while the review count is modest, the unanimous top marks suggest early adopters are genuinely satisfied. The blades are sold on Amazon.fr and first became available in June 2025, making them a relatively recent addition to the market.

This blade set is ideal for DIY renovators and tradespeople who need a reliable, durable cutting solution for wood, PVC, copper, and drywall in tight or awkward spaces — especially when working with nail-embedded timber where standard blades wear out fast.
