This bit is called a Self Centering Hinge Bit. Or Vix bit #hinges #drillbit #cabinets #tools | Go Build Stuff

A lot of questions about how this bit works and what brand it is • This one is sized for the door hinge holes and is spring loaded • I was picking up materials last week and found the exact same bit at Depot and it’s a RYOBI TOOLS USA But there is a lot of different brand that make these. I believe someone said Lowe’s had Kobalt ones. You can also find higher quality ones at woodworking stores . . . #construction #tools #tips #carpentry #home #homerenovation #renovation #door #installation #buil
