The frustrating search for your spanner wrench is coming to an end with the new Bosch X-Lock grinder and wheel system. It looks like a wheel attachment system that will change the grinder game the same way Starlockdid for multi-tools.

[alert heading=”10-Second Summary” type=”alert-info” block=”false” close=”false”]

• New system consists of grinders and wheels with tool-free wheel changes
• Expect bonded discs, flap discs, wire wheels, and diamond blades to start
• Most accessories will be backward compatible with standard 7/8″ mounts[/alert]

Bosch X-Lock Grinder System

There isn’t a ton of information out on the system so far, but we expect to see it in person at World of Concrete in a few days. We’ll update this article then.

What makes this interface tough is that you have to secure a wheel that’s spinning 10,000 RPM or more and deals with a lot of force. So far, there hasn’t been much straying away from the classic flange nut, so it will be interesting to see the final product.

What we do know is that we’re looking at two different product classes: Bosch X-Lock grinders and Bosch X-Lock accessories.

While there aren’t any photos of the interface just yet, it has all the earmarks of the way Bosch and Fein tackled Starlock for oscillating multi-tools.

On the accessories side, Bosch tells us that most will be backward compatible with standard 7/8″ mount grinders. That’s good news for any shop that wants to stock one brand of wheels but has both X-Lock and standard grinders.

The attachment system is completely tool-free and there is an audible click when your wheel connects properly. When it’s time to change wheels, a lever releases the lock and ejects the wheel.

What Bosch Says

“X-Lock promises to bring another level of performance and ease of use for trade professionals who rely on a grinder to get the job done each day. Of all the interfaces that Bosch has created (e.g. SDS, jigsaw, oscillating), the angle grinder interface has proven to be one of the most intricate. But the innovative design of Bosch X-Lock addresses the need for functionality greater functionality in a go-to jobsite tool.”
