Close tolerance work demands the very best in tools, machines and materials. This is especially true in the field of precision boring and it is precisely why the engineers at Criterion developed the TABH-250B and TABH-300D Tenth Adjusting Boring Heads. Featuring two micrometer adjusting screws, they are rugged enough for general boring, yet are capable of adjustments down to .00005". They are perfect for those special jobs that demand absolute size control. Their reliability and ease of operation make it easy to maintain close tolerances.
