Starrett 66935 Machinist Precision Level 6 in

Product Description

The STARRETT 66935 is a machinist-grade precision level designed for high-accuracy surface and alignment work in machine shops, tool rooms, and manufacturing environments. The level features a brass tube vial construction with ground and graduated main vials, delivering a sensitivity of 0.005 inches per 10 inches. At 6 inches in length and 1.1875 inches wide, it fits comfortably on machine beds, lathe ways, milling tables, and similar flat surfaces. Two horizontal vials allow for simultaneous readings in multiple planes. This instrument is installed and used by machinists, millwrights, and precision maintenance technicians who require repeatable, fine-tolerance leveling verification.

The STARRETT 66935 is suited for use in precision machine setup and alignment applications in both production and maintenance settings. It is appropriate for leveling and tramming operations on machine tools, surface plates, and other precision fixtures where base flatness and sensitivity tolerances are critical. The 1/64 inch base flatness specification ensures reliable contact with machined reference surfaces. It is a single-unit item with a package quantity of one.

Key Features

Compatibility

Designed as an OEM-style machinist precision level suitable for general machine tool setup, alignment, and leveling applications on flat machined reference surfaces.

Installation Notes

This instrument is used by machinists and millwrights during machine setup and alignment procedures. Before use, ensure the reference surface is clean and free of chips, burrs, or coolant that could affect vial readings. Handle with care to avoid impacts that could damage vials or alter base flatness. No power source or lockout procedure is required, but surrounding machinery should be secured and de-energized when performing alignment work nearby.
