Product Description

The Starrett 486P-3 Blade Micrometer measures the thickness of thin metal parts, such as the thickness of a thin film. They use a blade that slides along the part and presses down on it, done at an angle to ensure more accuracy.

Readability Features

  • Starrett satin chrome finish – no glare – resists rust
  • The balanced frame and thimble design ensure easy handling and better readability
  • Advanced sleeve design with staggered lines and distinct figures for precise and accurate measurements

Ease of Handling Features

  • The Speeder is the perfect tool for adjusting blades quickly on all sizes of micrometers.
  • Its non-rotating spindle prevents the blades from turning in narrow slots or rolling off the shoulder.
  • The blades are .030″ (0.8mm) thick, allowing them to measure to a depth of 5/16″ (8mm)

Accuracy and Long-Life Features

  • Rigid steel frame ribbed for extra strength ensures that the 486P-3 can withstand even the most strenuous of uses
  • Hardened one-piece spindle also helps prolong the life of the micrometer
