Description
Condition
Used (Pristine).
This micrometer is in pristine, well-cared-for condition. The instrument is clean, showing virtually no signs of wear, and the mechanical action is smooth and precise. The measuring points are sharp and undamaged. It comes supplied in its original fitted plastic case, complete with the adjustment spanner.
Product Overview
The Mitutoyo 112-201 is a specialised “Point Micrometer” featuring a pointed spindle and anvil with a 30° included angle. This distinct geometry allows the instrument to measure dimensions that standard flat-anvil micrometers cannot reach, such as the web thickness of drill bits, small grooves, keyways, and other recessed features. The measuring points have a fine radius (approx. 0.3mm), enabling contact within very narrow slots. The unit is equipped with a ratchet stop mechanism to ensure a constant measuring force, preventing the sharp points from digging into the workpiece or providing inconsistent readings due to operator variability.
