Starrett 50442 Machinist Precision Level 8 Inch Cast Iron

Product Description

The STARRETT 50442 is a machinist-grade precision level built for accurate surface and alignment checks in industrial and shop environments. The cast iron body measures 8 inches in length and provides two horizontal vials, including a ground and graduated main vial for reliable readings. 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 two resolution options in a single tool. Base flatness is held to 1/64 inch, ensuring stable contact with machined surfaces. This level is suited for machinists, millwrights, and precision equipment installers working to tight tolerances.

The STARRETT 50442 is used in machine tool setup, surface plate work, equipment leveling, and alignment tasks where high sensitivity is required. Its compact 8-inch length fits standard machine beds and workholding fixtures. The cast iron construction resists flex and maintains dimensional stability across typical shop temperature ranges. It is appropriate for both production and maintenance applications in manufacturing facilities, tool rooms, and machine shops.

Compatibility

Designed as an OEM-style machinist precision level suitable for general machine tool setup, surface alignment, and equipment leveling applications where 8-inch format levels are specified.

Installation Notes

Machinist levels of this type are typically set and read by machinists or millwrights during equipment installation or alignment procedures. Clean and deburr all contact surfaces before placing the level to ensure accurate readings. Power down and lock out any machinery before performing leveling or alignment work. Protect the ground base from impact and corrosion to preserve calibration accuracy.
