Starrett 50441 Machinist Precision Level 4-7/8 Inch

Product Description

The STARRETT 50441 is a cast iron machinist precision level designed for high-accuracy leveling work in machine tool setup, surface plate inspection, and equipment alignment applications. It features two horizontal vials, including a ground and graduated main vial, with a graduation sensitivity of 0.005 inches per 10 inches for fine-resolution readings and 0.05 inches per 10 inches for rapid leveling. The level measures 4-7/8 inches in length and 1-3/32 inches in width. Machinists, millwrights, and tool-and-die technicians rely on this type of instrument when setting up lathes, mills, surface grinders, and other precision machinery where exact horizontal reference is critical.

The STARRETT 50441 is suited for precision machine tool setup in both job shop and production environments. It is used on machine beds, ways, and mounting surfaces where small deviations in level directly affect workpiece accuracy and surface finish. The dual-sensitivity vials allow the technician to achieve rough level quickly before dialing in with the finer graduation. This level is appropriate for any trade or industrial setting that requires verified horizontal reference during equipment installation, maintenance, or calibration.

Key Features

• Fine graduation sensitivity: 0.005 inches per 10 inches for high-resolution leveling
• Coarse graduation sensitivity: 0.05 inches per 10 inches for rapid rough leveling
• Two horizontal vials for versatile orientation checks
• Ground and graduated main vials for reliable, repeatable readings
• Cast iron construction for durability and thermal stability on machine surfaces
• Compact 4-7/8 inch length fits on confined machine ways and beds

Compatibility

Designed as an OEM-style machinist level suitable for general precision machine tool setup, surface plate work, and equipment alignment applications requiring fine leveling sensitivity.

Installation Notes

Machinist levels should be placed on clean, burr-free surfaces to ensure accurate readings. Power down and lock out any machine before placing the level on moving components or machine ways. Avoid dropping or impacting the level, as shock can damage the vials and affect calibration. Verify the level against a known reference surface before beginning critical setup work.
