3-Point Internal Micrometer Holtest

Mitutoyo 3-point Economy Series Holtest Internal Micrometer
The Mitutoyo 368-764 offers an affordable yet accurate solution for measuring internal diameters - from holes and bushings to cylinders and tubes. The three-point measuring system is designed to provide a stable and automatic internal dimension without complex adjustments.
Key features and benefits:
- The micrometer is automatically positioned in the centre of the target - the measuring surfaces are evenly distributed around the hole or bushing, ensuring measurement orientation and symmetry of the result.
- Ideal for inside diameters where measurements can be challenging - holes, bushings, pipes, and cylinders are easily aligned with Holtest measuring surfaces.
- Mechanical design makes the micrometer lightweight and easy to use - no batteries, no electronic parts, just an accurate measuring screw and a readable scale.
- Competitive alternative for internal measurements - good value for money when you don't need digital features
- Measuring surfaces made of tool steel
Suitable for both workshops and machine shops where a reliable and affordable measurement solution for internal diameters is required.
Applications:
- Holes and bushings in metal parts - internal diameter verification before assembly or welding
- Pipes, cylinders, and bushings - accurate internal dimensions, regardless of whether the space is deep or the surface is difficult to reach
- Inspection and fabrication of tools and machine parts - where the accuracy of the internal diameter affects the compatibility of parts
- Repair and workshop work where an inexpensive but reliable internal measuring instrument is required.
