Re: [mill_drill] Boring head?
- The boring head I got from Enco was listed as 2 1/2 inch, 4" capacity, catalog # 328-0184 for $54.36, and I probably bought it from their sale catalog on 2/19/2010. Enco is real good about free shipping; just get the current code number from their sale catalog or from someone on this web site. Contact Enco to get on their mailing list and get the sale catalog every month.-----Original Message-----

Can you give me the model number of the Enco boring headThanksGP
- My bifocals like more graduations..... it's a lot easier for me.
My lathe has non direct dials....not much matter anymore. I installed a DRO years ago.

Direct reading might be *slightly* more convenient mentally, but there is no change in precision. The adjustment thread is still 20 TPI. The screw head is simply marked in 100 steps rather than 50.
I have no trouble at all in splitting the marks on my non-direct reading boring head.
But then I am using an old SB lathe with non-direct dials as well.
