TS 55: fine depth adjustment

[nikev]

Hi,

I notice that there is a remark in the TS 55 user manual that it's possible to set the depth of a cut with precision up to .1 mm by inserting an M4 grub screw in the depth stop control.

Has anybody tried this? I can't see how to determine what the precision adjustment is set at -- obviously turning the screw changes the depth, but how do you know how far you've gone, and how to get the adjustment back to zero?

Thanks in advance,

Nike

Nike,

Does this help?

A metric screw is designated by an "M" followed by its diameter in millimeters. An M4 screw, for example, is metric with 4 mm diameter. Thread pitch on a metric screw is usually a function of its diameter. For example, an M4 screw has a pitch of 0.7 mm per turn.

Thanks Len. That does help, but I still don't see where the zero adjustment setting would be....

To my knowledge, the TS 55's fine depth adjustment is designed as a trial and error feature. As a consequence, there's no scale which could help you to determine the settings.
I was told that the fine depth adjustment is primarily used by woodworkers who replace damaged pieces of parquet floors. They set the cutting depth stop at the cutting depth they expect to need, perform a cut, fine-adjust the cutting depth, cut again, check the depth, fine-adjust again if required etc.

Hope this helps,

Christian

I'm with you Christian there is no zero scale.  One just adjusts from the last point.  I think the idea is to sneak up on the depth you want by using the fine adjustment screw.  But it is sorta nice to know how much you are advancing the cut each time.  But generally you are advancing the cut some "immeasurable" amount

So after a call to Festool, I think I know what the deal is. The grub screw is used to calibrate the scale on the usual depth adjustment knob. So if your saw goes out of whack, you can reset it so that the depth shown on the scale is the actual depth of the cut. You can also tune the depth scale for different materials.

Thanks for all the answers.
