برغي التغذية، مسند المركب، مخرطة منضدية 20 TPI

The 20 TPI threading is dead on, and the fit on my compound rest was perfect right out of the box. I've got my lathe cutting clean again after a weekend of fiddling, and it's held up through a few hours of use without any slop.

Finally got my SIEG SC4 back in action with this feed screw — the 20 TPI threads mate perfectly with the compound rest cross slide. Installation was straightforward, and the slop I used to have is completely gone now.

The threads on this 20 TPI screw are cut clean and true, so the compound rest moves without any of the gritty hesitation I was dreading. It slid right into place on my SC4 and took up the backlash nicely. Just what the old worn-out one needed to be replaced with.
