Reliable adapter

Been using it for two weeks now on various projects. The black oxide finish seems resistant to rust so far. Deducted one star only because shipping took longer than expected.

Great value for money

Much cheaper than buying a dedicated tool. The machining precision is surprisingly good for the price point. Highly recommend for hobbyists.

Good quality but instructions needed

The steel feels very durable and the coating looks professional. It took me a while to figure out the exact spacing for my specific grinder model, but once installed, it works great.

Solid construction

No play in the connection at all. I've used it for polishing metal surfaces and light drilling, and the shaft remains stable even under load.

Works but requires modification

The adapter itself is fine, but I had to grind down a small part of my grinder housing to get it to sit flush. Check your specific model dimensions before buying.

Perfect fit for my project

This adapter worked exactly as described. I converted my old angle grinder into a drill press attachment using a 775 motor, and the M10 thread held tight without any wobble.

5 FAQ

Q: Will this fit a standard 4-inch angle grinder?

A: Yes, this adapter is specifically designed for 100 type (4-inch) angle grinders with an M10 spindle thread.

Q: What is the maximum drill bit size this can hold?

A: This depends on the M10 chuck you attach to the adapter. Typically, M10 chucks can hold bits ranging from 0.5mm to 10mm in diameter.

Q: Can I use this with high-speed 775 motors running at 20,000 RPM?

A: While the adapter is made of high-strength steel, we recommend operating within the standard speed ratings of your specific angle grinder housing to ensure safety and longevity.

Q: Does the package include the chuck key?

A: Yes, the package contents include one adapter shaft and one chuck key for tightening the M10 chuck.

Q: Is the shaft hollow or solid?

A: The connecting rod bushing is solid to maximize torque transmission and minimize vibration during operation.
