SERIES 368 - Holtest Three-Point/Two-Point Bore Micrometers
Non-digital 2-point & 3-point Mitutoyo bore micrometers, suitable for measuring the diameter of small holes. Hardened steel contact faces. Ratchet stop guarantees repeatable measurement.
- Ratchet Stop ensures constant-force, repeatable measurement.
- Optional setting rings are available for setting the instrument accurately before measurement.
- Three-point bore micrometer with a measuring range of 6 mm or larger allows stable measurement through automatic centering.
- Can measure deep holes using an Extension rod (optional) which is available on models over 6 mm (.275") measuring range.
- Titanium-coated measuring pins on the three-point type (over 6 mm range models) provide excellent durability and impact resistance and allow the instrument to measure right to the bottom of a blind hole.
