10 Best Dial Calipers 2025 in the United States

The Mitutoyo 505-746 Dial Caliper is a solid choice for precision measurement tasks. With a measurement range of 0-12 inches and an accuracy of 0.002 inches, it meets the needs of users requiring detailed and accurate measurements. The dial resolution is 0.1 inches per revolution, which provides clear and easy-to-read increments, making it user-friendly even for those less experienced with calipers.

The caliper's titanium nitride coating on the sliding surface enhances wear resistance, ensuring durability over long-term use. The lock screw feature for the digital bezel and sliding jaw position adds to its ease of use, allowing for stable measurements without slippage. One notable strength is its well-designed digital movement that promotes ultra-smooth sliding and high shock protection, making it reliable and robust for industrial and scientific applications.

While the accuracy and build quality are commendable, the caliper lacks modern digital readout features that could benefit users who prefer digital displays over traditional dial readings. The Mitutoyo 505-746 is ideal for professionals and serious hobbyists who prioritize precision and durability in their measuring tools.

The Starrett 120 Series Dial Slide Calipers are designed for precise measurements, with a measurement range of 0-6 inches and an accuracy of +/-0.001 inches. These calipers feature a white-face dial with a resolution of 0.001 inches, making it easy to read and reliable for detailed measurements. Made from hardened stainless steel, they are durable and robust, ensuring long-lasting use.

The calipers include a fitted plastic case for protection and portability, and the lock screws for the dial bezel and sliding jaw add to their practicality. Ease of use is enhanced by the thumb-operated fine adjustment roll and knife-edge contacts for both inside and outside measurements. This makes it suitable for both professionals and hobbyists who require precision in their work.

However, some users might find the dial mechanism less convenient compared to digital options, and the need for manual calibration could be a minor drawback. It is a solid choice for those who value accuracy and durability in their measuring tools.

The Mitutoyo 505-742J Dial Caliper is a reliable measurement tool with a 0-6 inch range and an accuracy of 0.001 inches, making it suitable for precision tasks. The new dial movement design ensures smooth sliding and high shock resistance, enhancing durability. Its improved finish on sliding surfaces contributes to its longevity, while the lock screw for the dial bezel and sliding jaw position secures the measurements, providing consistency and reliability.

The redesigned face improves readability, making it easier for users to take accurate measurements. This caliper can measure outer diameters (OD), inner diameters (ID), depth, and steps, offering versatility for various applications. However, the caliper is made of plastic, which might be less durable compared to metal alternatives.

Despite its quality and features, the plastic construction could be a concern for users needing more rugged equipment. This product is ideal for those who require precise measurements in a non-demanding environment, such as hobbyists or those working in light industrial settings.
