Condition
New.
This dial test indicator (DTI) is a brand-new, unused item. It is supplied in its original Mitutoyo packaging, complete with the plastic storage case, standard mounting accessories (stem and clamp), and the certificate of inspection.
Product Overview
The Mitutoyo 513-415 (Series 513) is a specialised Long Stylus lever indicator designed to reach where standard indicators cannot. While a standard DTI typically has a stylus length of around 15mm-18mm, this model features a significantly extended 44.5mm stylus.
This extended reach makes it the perfect tool for centering deep bores, aligning internal grooves, or checking runout on features that are obstructed by other machine parts. Despite the long lever arm, it maintains a measuring range of 1.0mm with 0.01mm graduations. The internal movement is jewelled for high sensitivity and low hysteresis, and the bezel is sealed with an O-ring to prevent oil and dust ingress.
Brand Information
Mitutoyo Corporation (est. 1934) is the global benchmark for dimensional metrology. Their Series 513 “Lever Indicators” are widely regarded as the most durable and smooth-acting in the industry. The 513-415 specifically solves the common machinist’s problem of “running out of reach” without sacrificing the precision needed for final alignment.
