Description
Condition
New.
This dial test indicator is a brand-new, unused item. It is supplied in its original Mitutoyo packaging, complete with all factory accessories, including the mounting stems (typically Ø8mm and Ø4mm), the knurled clamp ring, and the inspection certificate. The ruby contact point is pristine, and the movement is factory-fresh.
Product Overview
The Mitutoyo 513-471-10E is a premium version of the standard lever-type Dial Test Indicator (DTI), distinguished by its Ruby Contact Point. While standard steel or carbide tips can wear down over time or become magnetised, the synthetic ruby tip is non-magnetic, non-conductive, and incredibly resistant to wear (second only to diamond in hardness).
This specific material choice makes the 513-471-10E the ideal instrument for EDM (Electrical Discharge Machining) environments, where a conductive steel tip could cause arcing or pitting. It is also perfect for use on magnetic chucks or grinding machines, as the tip will not pick up magnetic swarf that could distort the reading. The indicator features a measuring range of 0.8mm with 0.01mm graduations on a glare-free, yellow-face dial. The internal movement is jewelled for high sensitivity and features an O-ring seal on the bezel to prevent oil and dust ingress.
Brand Information
Mitutoyo Corporation (est. 1934) is the global leader in precision metrology. The 513 Series is the industry benchmark for test indicators, found in almost every professional machine shop. The “Ruby Tipped” models represent the high end of this series, designed for specialist applications where standard tooling would fail due to magnetism or rapid wear.
