Dial Bore Gages - Mitutoyo

The performance of the well-established Mitutoyo Holtest series, well-known for their highly stable three-point self-centering action, has been enhanced by coating the contact surfaces with titanium nitride for longer life.

Features include...
  • Titanium-coated measuring pins provide excellent durability and impact resistance and allow the instrument to measure right to the bottom of a blind hole.
  • Three-point design assures self-centering action for stable measurements in ranges above 8mm bore diameter.
  • Bore micrometers are fitted with constant-force ratchets which enable consistent measurements with minimum variation between operators.
