Werka IP65 Three-Point Internal Micrometers

Micrometers measure a step finer than calipers: a screw spindle reads to 0.01 mm or 0.001 mm. Each covers a 25 mm range (0-25, 25-50 ...), so they are used in sets. Outside, inside, three-point bore, depth, tube wall, sheet, gear tooth and blade micrometers are chosen for the shape of the surface being measured. This family comes in 13 options: 6-8mm/0.275-0.35″, 8-10mm/0.35-0.425″, 10-12mm/0.425-0.5″, 12-16mm/0.5-0.65″, 16-20mm/0.65-0.8″, 20-25mm/0.8-1″, 25-30mm/1-1.2″, 30-40mm/1.2-1.6″, 40-50mm/1.6-2″, 50-63mm/2-2.5″, 62-75mm/2.5-3″, 75-88mm/3-3.5″, 87-100mm/3.5-4″. The order code of each is in the specification table; quote the code when you ask for a price.
