Sturdy and reliable

I use this daily in my small fabrication shop. It hasn't slipped once even under moderate load. The black oxide coating seems to resist rust well too.

Essential for DIY projects

Exactly what I needed to adapt my hand drill for finer work. The range from 1.5mm to 10mm covers most of my hobbyist needs. Highly recommend for home workshops.

Good quality, slightly tight at first

The steel feels solid and well-machined. It was a bit tight getting the chuck seated initially, but after a few uses, it slides on smoothly. Holds 10mm bits with no issues.

Works well but needs cleaning

The product works as described, but it came with some heavy grease that needed to be cleaned off before use. Once cleaned, the grip is excellent.

Great adapter for the price

For the cost, you can't beat this connector. It transformed my standard drill into a more versatile tool. Just make sure your machine actually uses the B12 taper before buying.

Perfect fit for my bench grinder

This B12 sleeve fits perfectly into my old bench grinder setup. The taper is precise, and it holds the drill bits securely without any wobble. Great value for a workshop accessory.
