Insize 3227 Two Points/Three Points Internal Micrometers
The Insize 3227 Two Points/Three Points Internal Micrometer series is a traditional, non-digital mechanical micrometer built for accurate internal bore measurement. Smaller ranges use two-point contact, while mid and larger ranges use three-point contact for even, consistent readings around the bore. Meeting the DIN 863-4 standard, each micrometer features a ratchet stop for consistent measuring pressure and is supplied complete with a setting ring, and larger ranges also include an extension rod. Covering diameters from as small as .08" (2mm) up to 12" (300mm), and available as individual gauges or as sets with multiple interchangeable measuring heads, the 3227 series is a dependable option for machine shops, tool rooms, and inspection labs that need reliable internal diameter measurement without the added complexity of a digital readout.
