Hi everyone,

I'm new to this forum.
My question is not answered at neither the Festool web page nor the manual for the machine, as I see it.

I can measure the total length from the bottom of the clamping collet to the base, so I guess I can just subtract a millimeter or two to be sure the bit I buy is not too long.

But is there any official max bit length for this model?

Best regards

Hello Nicolaj, there is no official length set for this router. In theory, you can place any 8 mm bit you find in it.

In practice it will be difficult to find 8 mm bits that stick out further than is safe to use, because manufacturers are aware of size limits. Use your common sense, and be aware yourself that really long bits can break due to the forces involved. I would think that as long as you stay under 30 mm depth of cut you're ok. But with deeper cuts it is always best to make multiple passes before reaching the final depth.

This.

The max length is a property of the bit, not the router.

A bit from crappy steel may handle 20 mm extension only barely while a quality specialist bit may handle 30 mm extension "with ease".

Always follow the bit manufacturer guidance - including the max rotation speed which may be lower for the bigger bits than the given router max speed.

I've only seen the insertion depth marking on Festool router bits. The other bits I use, Whiteside, Amana & CMT don't provide depth marks.
 
Are you sure about that? I always interpreted the sideways K-like mark on my CMT bits as the preferred insertion depth.

CMT mentions 75% minimum shank engagement in their safety recommendations. Not sure how that corresponds to markings on the bits.
 
I don't know about "all" of them, but the Amana insert style bits definitely have the insertion marks.
