Not a great range of lengths but did the job and will be a great kit for many years to come.
Fantastic thanks!

Step Drill Bit Hss Steel Titanium Cone Bit Hole Metal Cutter - 6mm up to 40mm

Ok
Did the job but I would say it goes from 6mm to 39 mm as I had a light bulb fitting that was 40mm and still have to use a file to make it fit through the freshly drilled hole. The light fitting was exaclty 40mm as I meansured it with my digital verier gauge.
