Starrett 65862 Depth Gage Base Extension 12 in

Product Description

The STARRETT 65862 is a depth gage base extension designed to increase the measuring reach of compatible Starrett dial depth gages. Constructed from stainless steel, this extension adds 12 inches of base length, allowing technicians and machinists to accurately measure deeper bores, slots, and stepped features that fall outside the standard gage range. The stainless steel construction resists corrosion and wear under shop-floor conditions. Installation is straightforward and requires no special tooling beyond what is typically used during gage setup.

This extension is suited for precision measurement applications in manufacturing, maintenance, and inspection environments. It is used when a standard depth gage base does not provide sufficient reach for the workpiece geometry at hand. The 65862 is intended for use with Starrett dial depth gage model 450-12, Starrett dial depth gage model 450-6, and Starrett dial depth gage model 450M-300. Machinists, quality control technicians, and tool-room professionals are the primary users of this accessory.

Installation Notes

Installation is typically performed by a machinist or metrology technician during gage setup. Ensure the dial depth gage is fully zeroed and calibrated after attaching the extension to maintain measurement accuracy. Handle stainless steel precision components with care to avoid nicks or burrs on mating surfaces that could affect gage readings.
