45mm Forstner Drill Bit

Our sprung door handles are designed with low-profile roses, so we’ve had to engineer the sprung mechanism so it recesses into your door.  

To install any of our sprung door handles, you’ll need to drill a 45mm pocket into the door for the mechanism. Our 45mm Forstner drill bit is specifically sized to allow you to easily drill the correctly sized hole.  

Use it with our retro fitting kit to achieve an accurate hole and prevent damage to your door.  

Watch our installation video here to see just how easy it is to use.
