HALJIAFlexible Drill Shaft Extension Keyless Chuck Compatible Tool Accessory Attachment for Dremel Rotary Tool

Good product. Used it a lot from day it arrived and it has not disappointed. Delivery and package as per seller claim.

for the uninitiated (like me), you have to hold the extension vertically then the springy bit drops out and you can then tighten the (square) end of the spring into the Dremel. Thread the other end of the spring back into the extension, the screw on the outer sleeve onto the Dremel and it should work - see pics. Hope this might help somebody

Brilliant to use easy to use just what was needed

I assumed it would fit, not a chance. Measure the hole in rotary tool to the faction of a millimetre to be sure.

Excellent value for a really useful tool that helped me out of a tight spot, literally

Broke very quickly, but did the job while it worked.

I was surprised by the amount of vibration when using this product. Bought for my Dremel, but can't use it on full power because it feels like my hand will fall off!

works like a dream
