FILENAMES: BoringHeadWohlhaupter.jpg DESCRIPTION: This is a picture of a large boring head. Posted by Mike M Fendley . The following description was provided: ================================================================= 28 lbs. of hardened and ground precision! What an incredible piece of tooling! It's a Wohlhaupter Universal Boring & Facing Head UPA 5. Just picked this up today hoping to use it on my mill. Alas, I think 28 lbs. on my spindle would tip my little mill over! (28 lbs. includes the massive std. 50 taper too.) Just incredible what this tool can do. (See latest Traver's catalog, page 445.) Wish I could use it, but my little mill would be internally hemorrhaging just to hang on to it! Mike
