Invisible Sponge BitSert

Didn’t think it kept the grinder bit wet enough so I’ve gone back to the sponge.

Installed as per video guides on YouTube which thankfully exist, but I struggled with my grinder not being perfectly level to feed water to the brush (I use a standing desk and when I lean on the grinder the water comes forward a bit), so I wound up overfilling my grinder trying to adequately wet the brush, and ultimately my bit is better kept wet with a sponge. Lesson learned!

I've been doing stained glass for years and only just started using the Invisible Sponge. It works! No more trimming sponges to fit and pushing the sponge around to try to keep water flowing,

Found the bitsert when purchasing other grinder parts and thought i would try it. Hate the sponges getting caught, not doing their job and sometimes just being in the way. Put the bitsert on and it is great. Don’t understand exactly how it brings the water up to work but it does a great job. Would love this for the smaller bits on the second level adapter!

I wish it was available in other bit sizes
