Wood Router, Snapping Cutters

[kingcreaky]

Hi All.

Just thought id offload one of those worries I have knocking round in my head. Its in regard to wood router cutters.

Something like this


I seem to go through them like hot dinners. and I wondered if anybody else has the same problem, or can perhaps advise me if I am missing something

Im using a standard 2.2kw chineese spindle, spinning at top wack 2200rpm? Ive checked its spinning in the right direction. all Im cutting is 3mm ply.

the workpeace is securely fixed down, and im only moving at around 2500mm/min @ around 4mm a pass

I seem to go through about one every hour, sometimes quicker. and at about £12 a pop its starting to take the biscuit

I even bought a couple of really expensive ones from ltc tooling http://www.itc-ltd.co.uk the guy said, he has never known one to break... my machine broke it in minutes

there doesnt appear to be any slop in the machine... (you can grab the neck of the spindle and hang on it, without feeling any play or movement)

any ideas, no matter how trivial they sound... would be appreciated. may have to post a video

in anticipation of your replies gents, thanks in advance
