Description
Product Overview
When you need to accurately inspect engine cylinders, bearing housings, or hydraulic sleeves for wear, taper, and out-of-roundness, the Mitutoyo 511-401 Dial Bore Gauge is the industry standard. This specific kit covers the highly versatile 15mm to 35mm internal diameter range.
- Thread-In Anvil System: Unlike larger bore gauges that use slip-in pins and spacing washers, this highly precise 15-35mm model utilizes a secure thread-in anvil system. This ensures absolute rigidity and zero slop when sweeping small-diameter bores.
- Self-Centering Mechanism: The gauge utilizes Mitutoyo’s legendary internal pendulum guide mechanism. This ensures the contact points automatically align dead-center within the bore, providing a perfectly repeatable reading without relying on operator “feel.”
- Carbide-Tipped Accuracy: The measuring contact points feature premium carbide tips, ensuring maximum wear resistance and strict accuracy even when sweeping rough cast-iron cylinder walls or abrasive materials.
- Build Your Own Setup: This listing is for the bore gauge body and anvil kit. It is designed to accept standard dial indicators, allowing you to install your own preferred resolution (such as a 0.01mm or 0.001mm dial). If you need an indicator, please contact us! We can easily match this up with a high-quality 8mm stem gauge from our inventory to create a ready-to-run package for you.
Condition
Used (Pristine Condition / Full Anvil Set).
This high-precision internal measuring kit is in exceptionally pristine used condition. It has been meticulously cared for in a professional environment and is completely ready to be paired with your indicator.
- The Anvils (Photo Note): Please note when viewing the photos that this kit includes the complete, full set of factory thread-in anvils. You will notice one empty slot in the case—this is simply because that specific anvil is currently pictured threaded onto the included 10mm extension piece!
- Mechanical Integrity: The bore gauge body mechanisms move freely without binding, transferring the internal movement flawlessly to the top stem.
