What Stands Out
8-Inch Precision
Designed for accurate measurements, this 8-inch caliper ensures exceptional precision when measuring inside dimensions for various applications, making it ideal for professionals and hobbyists alike.
Matte Finish
The matte finish reduces glare, providing a clear view of measurements in various lighting conditions. This feature enhances readability and user experience, ensuring consistent results in any workshop environment.
Solid Nut Design
The solid nut design provides enhanced durability and stability, ensuring that the caliper maintains its integrity over time. This longevity makes it a cost-effective tool for repeated use in demanding work settings.
Product Details
- TRANSFER INTERNAL MEASUREMENTS WITH CONFIDENCE - Gauge bore and cylinder diameters, then transfer the setting directly to a micrometer or precision rule for repeatable comparative measurements on the bench or shop floor.
- SELECTED STEEL CONSTRUCTION - Manufactured from selected steel with a bow-spring joint that holds settings under shop handling, giving you a measuring tool built to stay accurate through years of professional use.
- STABLE, DRIFT-FREE ADJUSTMENT - Legs pivot on a roller and are tensioned by a bow spring; the fulcrum stud rides on a large bearing surface that prevents side deflection so your reading does not wander mid-measurement.
- SOLID ADJUSTING NUT FOR FINE CONTROL - Open and close the inward-curving legs with the threaded solid nut to dial in the exact internal dimension, then lock the feel and carry the setting across the shop without slippage.
- 6 INCH / 150 MM PROFESSIONAL CAPACITY - Sized for machinists, toolmakers, millwrights, and maintenance technicians measuring internal diameters of cylinders, bushings, bores, and pipe IDs in machine shops, fab shops, and automotive work.

Groz Joint Calipers & Dividers Editorial Review
The Groz 01405 12" Spring Inside Caliper has garnered positive feedback from customers, who appreciate its high-quality finish and smooth operation. Users have noted that the nut moves back and forth seamlessly, allowing for effortless size adjustments when measuring. Many reviewers express strong confidence in its durability, particularly within tropical climates, and are pleased to find that it is made in the USA, which reinforces its quality perception. While the majority of feedback is encouraging, some users have pointed out areas for improvement. Notably, one reviewer mentioned that the caliper's finish appeared unpolished compared to their Groz 8" outside caliper, though they clarified that this doesn't detract from functionality. The spring mechanism has been described as slightly stiff, necessitating some user adjustment for optimal performance. Additionally, the presence of a heavy lubricant upon unboxing has warranted a clean-up step before the tool’s first use. Overall, the Groz 01405 is well-regarded among those seeking precision and sturdiness in their measuring tools, though there are minor aesthetic and practical aspects that could be enhanced. **
