CUP HINGES ON 16mm THICK DOOR & FORSTNER BIT
Hello,
I need to relocate/raise the bottom hinge on a 16mm thick MDF laminated door on the range cabinet. The forstner bit (or should I say, Forstner 'style' bit) I have purchased has a centre point which is approx 5mm high. Most others I've seen have same (but for a very expensive TCP bit.) The cup requires a 10/11 mm deep hole. This means I risk breaking through on the face. The frustration of my predicament is the bit I purchased was from Haefle - who I thought would have at least made some sort of notation on the packaging to warn of the limitations or otherwise of its usefulness.
Does anyone have any suggestions ie alternative brands which will produce a near flat bottom hole without the deep centre point.

I would do a couple of practice holes in a bit of spare timber. I reckon you will get the hang of it, with that bit. then do the actual cut.
cheers,

Yep. Make a jig and then file down the tip of the centre point!
Thank you.

In my years of white board cabinet making this was a problem every time we had to replace the 35mm cutter. What we did was take the cutter to the Saw Dr for him to grind away that 5mm protrusion of the point and leave just a "hint" of a point to start the cut. Yes its a pain but once done it will drill hinge holes for a very long time. OH.....don't try to drill a hole with out a jig!!! You will not be able to drill a hole accurately without a guide.
When making the hole a measurement of 4mm from the door edge to the circumference of the 35mm hole is critical (to give you a full range of hinge adjustment). For a jig, drill a hole in a piece of MDF clamp that to the door at the required position and drill just deep enough to hold the cup of the hingeJust do it!
Kind regards Rod

Take it back they have supplied the wrong cutter, Drill bit, without tip, ⌀ 35 mm, for concealed hinges - in the Hafele Australia Shop

Sorry mate, but that's not the manufacturer's job. It's your job to check that the product you choose is suitable for the purpose you want.
Really? Where were you buying drills? We always bought the TCT drills from Carbitool and never had a problem (I've honestly never even seen a drill like what's being described); no more than a 2mm point.
Did they supply the wrong one? Sounds very much like OP ordered the wrong one
Does anyone have any suggestions ie alternative brands which will produce a near flat bottom hole without the deep centre point.
One of these should do. https://www.carbitool.com.au/product/forstner-bits-carbide-tipped-metric/?special=search

The trick is to purchase a specialised hinge boring bit, not a forstner bit. Look similar but one is a specialised tool for one particular task.
