Product Description The set of internal micrometers that are highly accurate to a strictly minimal variance. For your confidence, they have undergone rigorous testing to guarantee consistent precision and quality. With anvils made of tungsten carbide, the micrometer is resistant to corrosion. These Three Point Bore Micrometers are used for accurately measuring bores. The self-centring measuring head consists of laterally positioned carbide anvils offset at 120 degree intervals. Their design allows these micrometers to measure close to the bottom of a blind bore. Key Features - Large measuring range without changing the anvil due to the patent structure - Large LCD display with digital read-out - Dual scale: convertible between metric and imperial units (mm/inch) - Has Data hold, ABS (Absolute) /INC (Incremental) and Tolerance modes (vary by model) - Preset memory and zero reset at any position - Accuracy conforms to DIN 863/BS 870 - Corrosion-resistant Tungsten Carbide measuring fac
