Are Multitool Blades Really Universal?

Are Multitool Blades Really Universal? 

Short answer: Not exactly. 
 Longer answer: “Universal” often means “mostly compatible,” but rarely perfect. 

 

 What Affects Blade Compatibility? 

✅ Mounting system – Starlock, OIS, quick-release, etc. 
 ✅ Blade shape – some brands use proprietary designs 
 ✅ The job – wood, metal, tile, and scraping each need different blades 

🔍 Bottom line: A blade might fit your tool — but that doesn’t mean it’ll cut well. 

 

Blade Mount Types 

1. OIS (Oscillating Interface System) 
 Most common – fits many major brands. 

2. Starlock / StarlockPlus / Starlock Max 
 Developed by Bosch & Fein. Super secure, no wobble. 

3. Universal Open Fit 
 Designed to fit most multitools — but not all. 

4. Proprietary Mounts 
 Found on many budget/off-brand tools. Compatibility is hit-or-miss. 

💡 Pro tip: Always check both the blade packaging and your tool manual. Some tools may need an adapter — but that’s not ideal on a job site. 

 

Cheap Blades – Worth It? 

Tempted by a 10-pack for $8 on Temu or AliExpress? It’s a gamble. 

🚫 They dull quickly 
 🚫 They bend under pressure 
 🚫 "Bi-metal" often isn’t real bi-metal 
 🚫 Mounts wear out after a few uses 

🔨 That’s why pros stick to trusted brands like Bosch, DeWalt, and Fein — or proven mid-tier blades that hold up under pressure.
