Iscar .01-4.9 .25-125mm BHFI MB63-63x87 Boring Head TPGX Carbide Insert 2 Slides

The installed IHFF 50 carbide insert cartridge arm takes TPGX 22xx 1103xx carbide inserts such as TPGX 221 222 110304 110308 etc. Boring range for this arm is 2.13-3.39" 54-86mm, but with the additional slides mentioned below, it can be extended even further. 

Comes with BHFH 30x75 and BHFH 30x135 sliding blocks for different boring ranges. I'd estimate roughly an 8-9" maximum bore with everything extended to max. Maybe 10", depending on how crazy you wanted to get.

Not a lot else to say, it looks to be in excellent shape, moves and locks up like it's supposed to.
