Oklahoma Joe's 4866405R06 Smoker Grommet Kit with Drill Bit, Gold/Black

i used a 1/4 inch cobalt drill bit to start the whole. then i placed a strong magnet next to the stepped bit. it will pick up all the shavings while drilling. i carefully drilled up to a slightly smaller hole then carefully drilled one step at a time. then test fitting it. carefully continued until the fit was tight. i also applied a small amount of black rtv into the groove just to bond it to the metal. then just worked the grommet into the hole and wiped off the excess. before installing the grommet put the step bit into the hole and mark the next larger step with a marker as an indicator when to stop. it makes it easier if you are drilling a second hole.

Step drill bit worked great for installing my thermometers and the silicone grommets. Stayed sharp. Use oil when drilling hole.

2 minutes to install... not a joke. I think the bit was worth more than the grommets themselves. Which begs the question. Why aren't these in from the factory? My old Smokie Mountain had one from the factory. But I've been running thermometer cables under the lid for the last 3 years on this thing and tearing them up. Problem SOLVED. *** Update *** Installed a 2nd set on my new OK Joe's Hitch grill. Once again simple install, perfect results. Can I give more than 5 stars?

The instructions leave a bit to desire the step drilldulls before you finish the first hole just for others the grommet needs a.3/4 inch hole.rhe instructions do not mention the hole size.gromets them selves do not allow the probes from a therm pro tp25 to fit without a small slicedit a proper sized hole nicelyno leaks even with the Alice an d 2 probes in each gromet

Easy installation and look very nice, it will be using them on Thursday with my Thanksgiving day turkey!
