An oscillating multi-tool is only as good as the blade attached to it. Put a cheap, soft-steel blade on a £250 trade machine and it will dull in seconds when hitting a hidden frame nail; put a premium carbide blade on an entry-level tool and it will cut through tough materials effortlessy.
Because multi-tool blades wear out fast during heavy work, UK tradespeople and DIYers are constantly searching for the balance between raw cutting speed, durability, and cost-per-blade.
In this guide, we break down the 5 best multi-tool blades and value multi-packs available in the UK, covering soft timbers, hardwood plunge cuts, nail-embedded wood, sheet metal, and tile grout.

Detailed Blade Breakdown & Recommendations
1. SMART Purple Series Titanium Bi-Metal (Best Overall for Wood & Nails)
If you are doing any type of renovation work where timber contains hidden wire nails or screws, the usual standard carbon steel blades will strip their teeth instantly.
This SMART Purple Series uses a titanium alloy coating over bi-metal teeth. This extends blade life significantly when cutting timber with buried metal fasteners.
- Best For: Cutting door architraves, floorboards, and timber with hidden nails.
- Fitment: Universal OIS (Fits DeWalt, Makita, Milwaukee, Erbauer, Parkside).
2. Saxton 35mm Coarse Japanese Tooth (Best Value Wood Cutter)
Japanese tooth blades feature staggered, razor-sharp teeth designed to slice aggressively through timber without clogging. Saxton Blades is a hugely popular UK brand that offers high-performance Japanese tooth blades at a fraction of the cost of big-name power tool brands.
- Best For: High-speed plunge cuts into softwood, plasterboard, and plastic.
- Fitment: Universal OIS (Also available in Starlock variants).
3. Bosch Expert Starlock Carbide Plunge Blade (Best for Hardened Metal)
When cutting through hardened steel bolts, copper pipework, or stainless steel screws, even bi-metal blades can struggle. The Bosch Expert Carbide blade uses individual carbide tooth strips welded onto the blade edge, lasting up to 50 times longer than standard bi-metal options.
- Best For: Heavy-duty metal demolition and pipe cutting.
- Fitment: Native Starlock / StarlockPlus (Fits Bosch Professional & Fein).
4. SMART Trade Carbide Segment / Mortar Buster (Best for Grout & Tile Work)
Removing old bathroom grout with a hammer and chisel is tedious and risks cracking tiles. A carbide grit segment blade ground down with coarse tungsten carbide particles grinds through old cementitious grout and plaster effortlessly.
- Best For: Bathroom & kitchen regrouting, chasing out plaster channels.
- Fitment: Universal OIS.
5. SMART Trade Rigid Scraper Blade (Best for Floor Preparation)
Multi-tools aren’t just for sawing—they are exceptional scrapers. A rigid steel scraper blade uses the tool’s micro-vibrations to peel up stubborn carpet adhesive, old linoleum backing, and thick silicone sealant without damaging the subfloor underneath.
- Best For: Stripping sealant, carpet glue, and old paint.
- Fitment: Universal OIS.

Frequently Asked Questions (FAQ)
Why do my multi-tool blades burn the wood?
Wood scorch marks happen when the oscillation speed is set too high or when using a worn blade. The friction builds heat instead of cutting. Reduce your machine’s variable speed dial to medium and use a coarse Japanese-tooth blade for deep wood plunge cuts.
Are cheap bulk multi-tool blade packs on Amazon worth buying?
Bulk packs (e.g., 20-piece sets for £15) are great for rough, dirty demolition work or cutting plasterboard where you don’t mind throwing away a dulled blade. However, for precise woodworking or cutting metal, investing in individual premium blades from SMART, Saxton, or Bosch will save you time and produce cleaner results.
