Flexibility of coupling shaft removes stress between the motor and driving components. It can play a role in the unexpected. Specifications: Material: 45# Steel Match Saw Blade Inner Hole: 6mm (M6) Match The Motor shaft Diameter: 3.17mm,4mm,5mm,6mm,8mm.(Pls choose one type) Review: Definitely useful - Handy to connect a motor spindle to other things. The motor spindle fits into the 6mm end and is affixed using the included set screw. The other end is threaded M6 rod and comes with a washer and nut to connect whatever it is you're hoping to put on the business end of the motor (such as a saw blade or pully or spur gear or whatever). The threaded bit is on the short side, extending approximately 8 mm. Using the included nut and washer you can put on a saw blade (or other thing) that's maybe 3 mm thick. I would say you are pushing your luck with 5 mm. That said, there's a lot you can do with what you're given. The set I got even included an extra set screw, those things are small and I can't be trusted not to lose tiny bits so that's a welcome addition. Overall, if you're needing a thing like this, this product should suit the task. Review: Smaller than the pictures show - No exactly what I was expecting, super small ## Features - Size - Length: 28mm/1.1"; Outer Diameter: 14mm/0.55"; Inner Diameter: 5mm/0.196". - Material - Made of #45 steel, good wear resistance, and fine precision thread can help you work easily and assemble easily. Smooth grinding, no looseness, long service life. - Application - The saw blade connection shaft is suitable for aperture cutting blades, saw blades, grinding wheels and other polishing tools. (The saw blade needs to be used with the spacer.) - How to use: The connection is simple, directly turn the motor into a good micro grinding wheel, and the motor into a micro electric saw, which can be reused. - Package include: 2 Set M6 5mm Motor Shaft Coupling ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | daier | | Part number | M6 5mm | | Item Weight | 50 g | | Package Dimensions | 13 x 8 x 1 cm; 50 g | | Manufacturer reference | M6 5mm | | Size | 5mm | | Item Package Quantity | 1 | | Batteries Included? | No | | Batteries Required? | No | ## Images ![2 Set Motor Shaft Coupling,M6 5mm Axle Motor Shaft Coupler Sleeve Saw Blade Coupling Saw Chuck Adapter - Image 1](https://m.media-amazon.com/images/I/61QRAP147gL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Definitely useful *by K***T on 3 March 2024* Handy to connect a motor spindle to other things.

They are pretty much the standard type that you get at this price point, so no frills, but they seem to be made well and are so far working perfectly. They go on the 6mm shaft nicely and they tighten down well, with no slippage so far, even when I cut some thicker aluminum panels than I will normally be cutting. ## Frequently Bought Together - 2 Set Motor Shaft Coupling,M6 5mm Axle Motor Shaft Coupler Sleeve Saw Blade Coupling Saw Chuck Adapter - Zeberoxyz 2PCS Set GT2 Synchronous Wheel 20&60 Teeth 5mm Bore Aluminum Timing Pulleys with 2PCS Length 200mm Width 6mm Belt (20-60T-5B-6) - 4Pcs 3.17mm Flange Coupling Connector, Rigid Guide Model Coupler Accessory, Shaft Axis Fittings for DIY RC Model Motors --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/666120415-2-set-motor-shaft-coupling-m6-5mm-axle-motor-shaft](https://www.desertcart.hr/products/666120415-2-set-motor-shaft-coupling-m6-5mm-axle-motor-shaft) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-28*
