hey all

Im making a new work bench for the shop, and on part of it i want to bore hole like that on the mft table.  I was going to use the LS system and not sure if i should use a 20mm spiral router bit (cmt makes) or the 20 mm hinge bit that festool offers.  I have both the 1010 and 1400 router also.  which i think the 1400 fits on the ls system.  I was going to use the shorter track and just index it for the length that i need.

Suggestions?

the hinge bit worked for me.

I also made a few tops with a regular non spiral CMT bit, and a OF1010, the biggest advice i can give is to make the cut in 3 rapid up and down plunges, this allows the chips to clear and uses the router inertia for the drilling.
Otherwise you start burning the mdf and the bit.
 
My MFT/3 holes measure 20.00 - 20.10 in the worn holes.  They do vary slightly among tops.
