Starrett 50445 Machinist Precision Level 18 Inches

Product Description

The STARRETT 50445 is an 18-inch machinist precision level built for exacting alignment and leveling work in machine shops, manufacturing facilities, and industrial maintenance environments. Constructed from cast iron, this level delivers a base flatness of 1/64 inch and carries three vials total, including two horizontal vials. The main vials are ground and graduated, offering sensitivity readings of 0.005 and 0.05 graduation per 10 inches. At 5.625 pounds, the unit is substantial enough for stable placement on machine beds, ways, and surface plates. Qualified machinists and millwrights rely on this level for precision setup tasks where standard spirit levels lack the required sensitivity.

The STARRETT 50445 is suited for precision alignment of machinery, lathes, mills, surface plates, and industrial equipment where tight tolerance leveling is required. The 18-inch length spans a wide contact area across machine ways and beds, supporting accurate two-axis leveling checks. Its cast iron body resists wear and holds dimensional stability under shop conditions. The dual-sensitivity vial configuration allows the technician to perform coarse and fine leveling without switching tools.

Key Features

Compatibility

Designed as a standard machinist precision level for use on machine tool beds, surface plates, and industrial equipment requiring high-sensitivity leveling. Catalog industry number 98-18.

Installation Notes

Machinist levels are typically placed and read by machinists, millwrights, or maintenance technicians during machine installation or alignment procedures. Clean the machine surface and level base thoroughly before placement to prevent debris from affecting readings. Do not use this level as a structural support or prying tool. Store the level in its case and away from impacts that could damage the vials or alter base flatness.
