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)

Ideal for small businesses

As a small family business, we understand the need for reliable, cost-efficient equipment. Rather than spending money on replacing heavy equipment or paying someone else to fix it, fix it yourself with our portable Line Boring Sets!
