Starrett 50444 Machinist Precision Level 12 Inches Cast Iron

Product Description

The STARRETT 50444 is a machinist-grade precision level built for trade professionals who require accurate surface and alignment readings in metalworking, machine tool setup, and industrial applications. Constructed from cast iron, this level measures 12 inches in length and features two horizontal vials with ground and graduated main vials. Graduation sensitivity is 0.005 inches per 10 inches on the primary vial and 0.05 inches per 10 inches on the secondary vial, giving technicians both fine and coarse reference in a single tool. It is the right choice when leveling milling machines, lathes, grinders, or other precision equipment to tight tolerances.

This level is intended for machinist and industrial maintenance applications where surface plate work, machine tool installation, and alignment tasks demand repeatable, high-sensitivity readings. The cast iron construction provides thermal stability and resistance to flex, which is critical when checking equipment beds, ways, and mounting surfaces in shop environments. It is a standard reference tool for maintenance machinists, millwrights, and precision equipment installers working in manufacturing and industrial facilities.

Key Features

• Primary vial sensitivity: 0.005 inches per 10 inches for fine alignment work
• Secondary vial sensitivity: 0.05 inches per 10 inches for quick coarse leveling
• Two horizontal vials for versatile orientation checks
• Ground and graduated main vials for accurate, repeatable readings
• Cast iron body for thermal stability and structural rigidity
• 12-inch working length suited to machine bed and surface plate use

Compatibility

Designed as an OEM-style precision reference level for machinist and industrial maintenance applications requiring high-sensitivity vial measurement on flat and machined surfaces.

Installation Notes

This level is a hand tool used by machinists and millwrights and does not require electrical isolation or utility shutoff before use. Clean the mating surface thoroughly before placing the level to prevent debris from introducing false readings. Avoid dropping or striking the cast iron body, as impact damage can alter vial calibration. Periodic calibration checks against a known reference surface are recommended to verify ongoing accuracy.
