Mitutoyo Mechanical Holtest Three-Point/Two-Point Internal Micrometers
The Mitutoyo Holtest mechanical three-point internal micrometer utilizes three self-centering anvils with precision contact points for accurate and efficient measurements of inside dimensions of bores (Holtest models under 5-6mm/0.24-0.28in - Two-Point Carbide Contact Points).
The Mitutoyo mechanical Holtest internal micrometer features three hardened-steel anvils evenly spaced at 120° for true alignment of the axis bore for accurate, easily repeatable measurements. Contact points are coated with Titanium Nitride (TiN) for added durability and precision (Holtest models under 5-6mm/0.24-0.28in - Two-Point Carbide Contact Points). The Holtest ratchet stop mechanism provides a constant measuring force on the hardened-steel spindle to ensure accurate, even measurements.
