I use T49/F49 on my Silca Matrix SX which are used for cutting Magnum dimples

My machine is a DEFU 998C, does the job for what i need it to do, the current cutter im looking at is a 105 degree dimple cutter but im wondering if a special cutter is needed for these dimples... Do you know how the angle on the T49/F49 compares to a 105?

F49 is a 0.8mm tip at 95 degrees

F42 is a 0.7mm tip at 100 degrees - this used for Garrison keys and would probably do the job as well.

So considering the variation of cutters that 'could' be used the 105 i have should do the job in theory? when the 105 is placed into the key from which i am copying it is not an exact fit between the edge of the cutter and the dimple on the key which is what was making me think there may be a specific cutter. It seems however, from what you are saying, that a wide variety will probably do the job. Am i right in thinking that?

I would presume yes, a cutter as near as should be fine.

I haven't cut many but I've not had any back.

I think @grahamparker advised me on what cutter to use, he's the expert.

The 95` cutter will work if it's sharp but it is tight using the Magnum. We found best reults with anything over 100`.

It is only 4 bearings that drop into the hole created allowing the plug to turn so it can be as wide as you like but it can weaken the blank if you cut in to deep.

Great, thank you for the advice, I really do appreciate it.  The cutter I have is a 105 so i should think we will be ok.

Same hear mustang great machine 100 or 105 , also is it me or does anyone else feel the tolerance on all these types of dimple keys are quite flexible compared to Cylinder Keys, I know on occasions i have maybe gone to deep or made the hole to wide but up till now not one back and I have cut a lot .

think you may have forgotten it also has dimples Graham, are you in holiday mode or do the original blanks come with the dimples pre cut ?

Yes, i get Genuine blanks pre-drilled saves a lot of time and they are cheaper.

Last day of my Holiday heading home tomorrow back at work Friday.
