Starrett 98-6 Precision Machinist Level 6" Ground & Graduated Vial with Cross Test

The Starrett 98-6 is a precision machinist level built for accurate leveling and alignment of machinery, surfaces, and structural components in demanding shop environments. With a 6" (150mm) cast iron base, ground and graduated main vial, and cross test vial, it delivers the sensitivity and reliability that metalworking, manufacturing, and tool room professionals require.

Key Features:

• Ground and graduated main vial — adjustable to a positive setting for accurate, repeatable readings
• Cross test vial — enables simultaneous leveling in two directions without repositioning the tool
• Sensitivity: 0.005" per foot (0.42 mm/m, 80–90 seconds of arc) — far exceeding the accuracy of standard construction levels
• Precision-machined cast iron base — provides a stable, durable reference surface
• Involute groove along the base — creates a reliable seat for leveling round workpieces such as pipes, shafts, and conduit
• Vial housed in a satin-finished brass tube — with a friction-fit closing cover to protect against breakage
• Isopropyl alcohol-filled vial — resists thermal effects across a wide temperature range
• Made in the USA — part of Starrett's improved 98 series available in 4", 6", 8", and 12" lengths

Sold without case. The Starrett 98-6 machinist level is an industry-standard tool trusted for machine tool alignment, surface plate setup, equipment installation, and precision layout work.
