Mitutoyo 368-771 Holtest Inside Micrometer, type II, 62 to 75 mm

Description

The Mitutoyo 368-771 Holtest Inside Micrometer, Type II, 62 to 75 mm, is a mechanical three-point internal micrometer designed for measuring the inside diameters of bores. This economical version of the standard Holtest features self-centering anvils made of alloyed steel.

Key features

• Three-point contact method: Features three self-centering, alloy steel anvils spaced at 120° to ensure consistent alignment and accurate measurements of internal bores.
  
• Constant force mechanism: Includes a ratchet-stop to provide a uniform measuring force, which helps ensure precise and repeatable measurements regardless of the operator's skill.
  
• High accuracy and resolution: Offers a graduation of 0.005 mm and a high accuracy of ±0.003 mm.
  
• Laser-etched scale: The thimble and sleeve scales are laser-etched, which makes them easier to read under various conditions.
  
• Economical construction: The Type II model is a more cost-effective option, using hardened tool-steel anvils instead of the more expensive titanium-coated carbide anvils found in standard Holtest models. This allows it to offer the same accuracy at a lower price point.
  
• Ability to measure blind bores: The design allows for measurements to be taken closer to the bottom of blind bores.
  
• Mechanical operation: This is a mechanical (non-digital) micrometer that provides stable tactile feedback.
  
• Protective case: It is supplied in a fitted plastic case for protection.
