Hi arm,
You're not a pain mate.
One of my boring bars has the designation S16Q SCLCR-09
Which probably does not mean much to you but it is an (ISO) (standard) nomenclature. [
that's a long word had to look that up 
]
Now S is the first letter/number =1
16 is the second letter/ number =2
Q is the third letter/number =3
and so on,
S=4
C=5
L=6
C=7
R=8
09=9
What does this all mean:
The first letter S=1 means it is a Steel Shank plain steel not carbide and no hole for coolant.
The second is 16 =2 simply the shank diameter. In this case 16mm
The third is Q= 3 Total length of the boring bar. In this case 180mm
The fourth is S=4 What type of clamping is used for the insert. In this case Screw.
The fifth is C=5 is the insert shape, In this case rhombic 80 deg.
The sixth is L=6 The approach angle. In this case 95 deg.
The seventh is C=7 is the relief angle. In this case 7 deg.
The eighth is R = 8 whether is it a right or left hand tool. In this case right hand (standard boring)
The ninth is 09 =9 (that 09 could be 06, 12,) is the length of the cutting edge of the insert. In this case 9mm.
Well there you have it I don't think I have explained it too good. I don't know this by heart I haven't remembered it I have to look it up
Here a pic (where I got the info from) you can see where the numbers come in. Sorry it is sideways I have no idea how to turn it
Figured it out
It does seem a bit complicated at first sight - the easy way is just ask a question
