Turn the Drill Guide counterclockwise and 
remove it from the Base. Insert the 35mm 
Concealed Hinge Bit into the Drill Guide and 
slide the Stop Collar onto the bit shaft until it 
is seated on the shaft shoulder. Tighten the 
set screw with the Hex Wrench. Set the Drill 
Guide/35mm Bit aside.
Consult your hinge manufacturer’s 
instructions for the distance from the edge of 
the door to the edge of the 35mm hinge-cup 
hole. Using a at-blade screwdriver, turn the 
Edge Indexers so the appropriate dimension 
aligns with the line on the Base. The edge-
of-door to edge-of-hole dimension usually is 
given in millimeters. For a dimension given as 
a fraction of an inch, see the cross-reference 
table directional.

WARNING The drill bit is sharp. Keep the cap on 
the bit until you are ready to drill. Wear gloves when 
handling an unprotected bit.
ATTENTION The drill bit included with this jig 
is a custom length with a shoulder for accurately 
positioning the Stop Collar. Use only a Kreg 35mm 
Concealed Hinge Bit as a replacement.
