Hello,

I have a Bosch GOF1300ce which is a fine machine. But somehow it has problem keeping speed when routing. Even with a 8mm straight router bit and hardly pressing the machine forward, it struggles.

Does anyone know what the problem is? I mean, with 1300w, there is more than enough power to keep even bigger router bits going and holding the speed.
I checked a while ago- the brushes are ok. I'm very tempted to think the fault is within the control unit that controls speed.

Thanks in advance

look to the brushes...

The brushes are fine (last time I checked them). No sparks when starting router. Router goes quick to indicated speed.

I actually found out what causes this problem. I ordered a new speed control, replaced the old one, and there were no difference at all. The old was not malfunctioning. What causes this is when I use a straight router bit, it's the debris that clogs up in its path. I tried a completly different bit; no sign of power loss while routing.

What diameter bit were you using and how deep of a cut?

A simple straight bit 8mm, from a set distributed by Bosch I bought many years ago, on full speed cutting in oak! That said, I dont think its a proper Bosch quality, but something cheap chintoc, and maybe thats why it struggles - the bit is not sharp as required?

If that's true Bj then up cut spiral bits would probably be your best choice. If I can I like to make a small groove with my table saw and then finish with the router. The saw groove makes a big difference as it gives some of the chips an escape path and it lets air get to the bit which keeps it much cooler.

Sounds like a very good idea to premake a path with a circular saw. I will try that next time ig same problem occurs with different dimensions!
