Review on 🔧 AUTOTOOLHOME 1/4 inch Hex Shank Pocket Hole Drill Bit Replacement Twist Step Drill Bit with Depth Stop Collar for Manual Pocket Hole Jig System - Woodworking Tools and Accessories by Jerry Mangum

Perfect size for mounting the floating shelf brackets I bought. You'll need one of these parts if you're hoping to use one of those floating shelf mounts on Revain. They all say they use a 3/8" bit, but they don't. it's just over 3/8" and just under 7/16". I used 10mm and 11mm. I start the hole at 11mm about 2/3 down and then finish the hole at 10mm. This makes the brackets easier to find in the holes in the shelves, they easily insert into the wall and then snap into place when almost flush.
