Router bit questions

[jason galbraith]

Hi, just a couple of quick questions regarding what router bits people use and speeds.
For cutting our 16mm melamine chip board we use a 9.5mm triple flute onsrud cutter at 18000rpm and 21000 feed speed. That seems to get us around 120 sheets of 2400x1800 before it needs re-sharpening. Does anybody have any other advice or better setup.
Next question, for boring hinge holes, and cam holes we are using a 12mm triple flute onsrud cutter which is our pocket tool, at 12000rpm. I am reasonably sure that this is the wrong type of bit to be using to do this operation. Advice please.

thanks for any input

regards

Jason

We run @ 24000 Feed and 20000 RPM on 18mm Chipboard With an Onsrud 60-126MW OR MC (marathon)

We Run @ 18000 Feed and 20000 RPM on 18mm MDF with an Onsrud 60-123MW or MC

We Use the 60-123MW to do Hinge holes at the same feed and RPM as above. We also have a 10mm drill bit in the bank to do the knock in holes of the hinge.

Feel free to email me with any more qu's @ thermwood@dawngroup.co.nz

And also i dont reshapen my tools. Just keep them for when we do timber or ply.

Thanks for that Thom. Could you tell me roughly how many sheets of melamine you cut before you have to change bits?

i cant tell u really! as i dont really keep count! I'd say mayb 300- 400. or even 600.

I know 1 lasted a month ( till the guy dropped it!) and we cut alot that month! over 400 sheets of mdf!
