Transfer punches are only intended to lightly mark the part and you should follow up with a centre punch.
I made some cheap M12x1.75 transfer punches when I made a chuck adaptor. I took three set screws and turned a 60° point on them and then milled two flats either side of the point, so I could screw them into place with some long nose pliers. Screw all three in, turn the chuck over and give it a tap. Three holes perfectly located.
