Question 1

Are multifunction tool attachments universal — will any blade fit any multitool?

Accepted Answer

No — multifunction tool attachments are not universal, and this is the most common and costly mistake buyers make. Each major brand uses a proprietary mounting system: Bosch uses Starlock or Starlock Plus, FEIN uses its Multimaster interface, Makita and DeWalt have their own systems. Universal adapters exist, but they introduce mechanical play that reduces precision and can be a safety risk at high oscillation speeds. Always check your machine's mount type before buying any attachment.

Question 2

What's the difference between a Starlock and a Starlock Plus blade?

Accepted Answer

Starlock Plus blades are designed for higher-torque Bosch machines and feature a deeper, more secure engagement with the tool's drive system. A Starlock Plus blade will fit a Starlock machine, but you won't get the full benefit — the extra torque transfer is lost. A standard Starlock blade will not fit a Starlock Plus machine. If you own a newer Bosch multitool, check which system it uses before buying blades in bulk.

Question 3

Is it worth buying a blade set or individual blades?

Accepted Answer

It depends entirely on your use case. For a one-off job, buy the specific blade you need — sets often include blades you'll never use. For a renovation project or if you're new to multitools, a mid-range Bosch or FEIN set around 11 £ to 25 £ gives you practical coverage without waste. Avoid very cheap sets: the individual blades within budget kits are often lower spec than equivalent standalone products from the same brand.

Question 4

How long should a multitool blade last before it needs replacing?

Accepted Answer

It varies significantly by material and blade type. An HSS blade cutting softwood might last 500–1,000 cuts; the same blade on hardwood or tile grout will blunt in a fraction of that time. Carbide-tipped blades typically last 5–10 times longer than HSS equivalents and are worth the higher upfront cost for any sustained work. A blade that's starting to drag, burn the material, or require excessive pressure is overdue for replacement — pushing a blunt blade risks both a poor result and tool damage.

Question 5

Can I use multitool blades for grout removal without damaging the tiles?

Accepted Answer

Yes, but only with the correct blade. A dedicated grout removal blade — typically 1.0–1.2mm thick and carbide-coated — is essential. Using a standard saw blade will almost certainly chip or crack the tile edges. Work at a low oscillation speed and keep the blade parallel to the grout line. FEIN's E-Cut range and Bosch's dedicated grout blades are the most reliable options for this task.

Question 6

Are Dremel attachments worth buying for a full-size multitool?

Accepted Answer

Generally, no. Dremel accessories are designed for Dremel's own rotary and oscillating tools, which operate at different speeds and with different mounting systems to full-size multitools from Bosch, FEIN, or Makita. Dremel's low average price reflects lighter-duty construction suited to craft and detail work, not trade use. If you own a Dremel tool, their accessories are good value; if you own a Bosch or FEIN multitool, stick to the correct system. Mixing systems with adapters is a false economy.

Question 7

What are the most common mistakes to avoid when buying multitool attachments in 2026?

Accepted Answer

The three most expensive mistakes are: buying on price alone without checking compatibility, using an HSS blade on materials that need carbide (it blunts almost immediately), and buying a large blade set when you only need one or two specific blades. A fourth, often overlooked: not checking whether the attachment is CE-certified. Non-certified blades from unknown brands may fail at high RPM — always look for CE marking and, where possible, buy from established brands like Bosch, FEIN, DeWalt, or Makita.
