A hinge bore is required if you need to use cup shaped euro hinges for awooden cupboard door.
The radius of the hinge bore is 17.5mm and it is also the centre point distance. Itwould be safe to have a 4-5mm shoulder from the side of the cupboard door. Sothe distance from the edgeto start boring is 17.5+4.5=22mm.
It is critical to bore the correct depth.Most cupboard doors vary in thickness from 16-22mm. The standard depth to bore is 13mm for most euro hinges.
Hardwoods require a slow speed when boring. The hinge bore can easily besharpened using a diamond file. Clickhere to have a look at the DMT diamond products.
TIP:
Use a drill press, it is easier to control the correct depth adjustment. It isalso possible to make a jig for future hinge boring.
