Installing a passage lock, where to start cutting the face bore?
This passage lock is a gift from a friend but I receive no paper template to prepare the face bore.
I do not have much experience with door lock installation. Therefore it is better to consult someone here and to ensure the face bore is prepared.
I don't need to worry the side bore as the existing door has one.

Please review the above picture. I am hesitating as my measurement shows it is at least 70 mm. From information elsewhere it appears normal passage locks should have a 60 mm backset and 70 mm is only common with deadlocks. This is the reason I am hesitating.
Thank you for reading.

With the latch assembly fitted to body of lock, if it measures 70mm, then drill centre from edge of door is 70mm. Face hole should be 54mm, not 50mm. When the pilot bit drills through opposite face, change sides and drill from opposite side otherwise you run the risk of a messy blowout that the lock dress rim wont cover.
Make sure you use a square to mark centre lines for edge and face, if they dont have a common centre line then you will have nothing but trouble with the lock.
Drill face hole first, then latch hole. Place latch in hole and temporary screw in place, use a box cutter knife to score the out line of the rebate for the latch, several deep scores for the sides and a good score top and bottom, remove latch, CAREFULLY remove waste, dont over do depth, sneak up to it, fit latch and and then lock being careful to correctly engage latch to body of lock. Then fit striker to jamb.The person who never made a mistake never made anything

Here in the US all door locks are standard. Rather than try to guess what the applicable measurements are, I can tell you how to determine the accurate measurements.
Go to another door with a lock set installed. Either passage or passage with a lock.
Remove the lock set. You may want to write on the door with a pencil so put masking tape around the holes.
Put a line across the top and bottom of the hole on the face of the door. Do the same for the locking pin on the edge of the door. Be absolutely precise and use a sharp pencil for the marks. It is best to use a square to align these marks.
Measure the distance between these lines. This distance gives you the diameter of the required holes. Write these numbers down and determine the radius of the holes by dividing them in half.
Measure from the edge of the door to the near edge of the hole. Do this for each hole. Add the appropriate radius to each measurement.
On the door where you are installing, draw a line on the face and wrap around the edge for the center of the latch set. From the math above, measure the appropriate distances on the line and mark. This will give you the location for the holes.

THANK YOU for taking time with the instructions in details. Did you reckon it must be 70 and never 68 or 73? I hope you've seen the picture I attached and verified the way I come up my measurement..
I've previously installed two other passage locks successfully. There is actually a helpful Bunnings DIY door lock video.

Yes, your X dimension will be 70mm. They are only 60 or 70 and some can be changed to do either. rw's info above is all you'll need.

Just to further confuse, some latches are adjustable from 60 - 70 mm

+1 for the Irwin lock fitting kit; I have one myself. It is designed for Imperial passage sets; however the Imperial settings 2-3/8" and 2-3/4" are for all intents and purposes the same as 60mm & 70mm. Works on both top quality "Gainsborough" and cheap "Icon" door sets.
Nothing succeeds like a budgie without a beak.
