Kennedy® External Micrometers

Kennedy® Enamelled Frame External Micrometers for taking external measurements accurately. The alloy steel spindle is held rigid in a drop forged steel frame and is fitted with a speeder type ratchet thimble for rapid adjustment and a fine adjustment thimble for taking precise measurements. The spindle can be locked in position by the using the spindle lock lever this retains the spindle position for reference. The anvils are optically flat tungsten carbide for a hardwearing contact surface that ensures precise measurements every time. Manufactured to BS 870.

Accuracy: Flatness: 0.6mm.
Parallelism: (2 + L/100)mm (fraction rounded down). Instrumental error: +/-(1 + L/75)mm (fraction rounded up).
L = maximum measuring length.

Multi Anvil Micrometer Set

An external micrometer with 7 pairs of interchangeable anvils. For measuring grooves, threads, bearings, tube & sheet. Anvils Included: 12mm disc, 5.5mm blade, 60 cone & blade, 6.5mm radius, 6.5 & 2mm flat.

Micrometer Ball Attachments

To suit the 1961, 1965 and 1966 series micrometers. Can be fitted to the anvil or spindle on external micrometers to enable round or irregular surfaces to be measured. The ball is hardened and moves freely to allow contact with the object being measured. Note: Always deduct the ball diameter from every reading.
