Diamond drill bits with an 1 ¼" UNC female thread and drill bits with R ½"
male thread can be screwed directly onto the working spindle.
Always use drill bits which match the material which has to be drilled.
You can prevent the machine from damage if you only use drill bits which are
balanced and not deformed. Pay attention that diamond segments have
enough relief cut towards the drill bit body.
Drill Bit Change
Attention!
When you use or sharpen the machine, it might heat up enormously.
You could burn your hands or get cut or ripped by the segments.
Therefore, always use protective gloves when changing the drill bit.
The drill spindle has a right-hand thread.
To hold on spindle always use an jaw wrench SW 32.
Never remove the drill bit with impacts because this way the machine will be
damaged.
With some waterproof grease, which is put on the drill bit thread, and a
copper ring between spindle and drill bit you can remove the drill bit easier.
