Portable Line Boring Sets
For the Best Results
SIMPLE, AFFORDABLE, EFFICIENT
Made in Chicago, USA, our Line Boring Sets include the tools needed to rebore most holes starting from 1” up to 8”. The boring bars are made from 1045 induction hardened and chrome plated precision ground and polished steel. The bars have square tool ports broached every 2.5” or 3” so the operator can get an exact measurement (within .001″) without having to remove the boring bar from the bore.
(Use Starrett 823 inside micrometer or similar)
