ACCURACY - PRECISION - RELIABILITY
Close tolerance work demands the very best in tools, machines and materials.
Criterion has improved the TABH Series of Micro Adjusting Boring Heads so they now adjust in 0.000050 on diameter.
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.
Tool holders for the CB-TABH Series, see V-Flange & BT Shanks and for the TABH Series see the Shanks & Adapters sections.

| HOW DOES IT WORK?
The 25 millionths (.000025) movement is accomplished by using a unique single sliding wedge concept. Our design allows the accurate and consistent adjustment of the tool in increments of 0.00050 in the bore. |
