Mitutoyo 513-446-16T Dial Test Indicator Kit 9 Pc

Product Description

The MITUTOYO 513-446-16T is a 9-piece dial test indicator kit designed for precision measurement in horizontal indicator applications. It features a 0.06-inch measuring range with a 0-15-0 dial reading, 0.0005-inch dial graduation, and 0.0005-inch accuracy. The 1.57-inch (40 mm) dial face is black with a glare-free crystal and scratch-resistant coating, making readings clear in shop lighting. The no-clutch structure and reversible measuring direction allow fast, repeatable setups. An O-ring seal protects against dust and coolant splash. Machinists, toolroom technicians, and quality-control inspectors use this kit for runout checks, surface parallelism, and fixture alignment work.

This kit is suited for horizontal indicator applications in toolrooms, machine shops, and quality inspection environments. The included accessories cover a range of common setups without requiring separate adapter purchases. The adjustable contact point and universal holder add versatility for angled or hard-to-reach measurement locations. The swivel clamp and holding bar allow mounting to standard indicator stands and magnetic bases commonly used in production and inspection workflows.

Compatibility

Designed as an OEM-style replacement or kit upgrade for horizontal dial test indicator setups in the MITUTOYO 513 Series. Stems, contact points, and clamp accessories follow standard dial test indicator fitment conventions common to 513-series instruments.

Installation Notes

Installation is performed by machinists or metrology technicians without specialized tools beyond standard indicator holders and magnetic bases. Mount the indicator securely in the swivel clamp or holding bar before zeroing the dial. Ensure the contact point stylus is perpendicular to the measured surface to minimize cosine error. Do not overtighten the clamp ring on the indicator stem, as this can affect spindle freedom and measurement accuracy.
