Mitutoyo 513-452-10T Dial Test Indicator 0.03 in Vertical

Product Description

The MITUTOYO 513-452-10T is a vertical-style dial test indicator designed for precision measurement in machining, inspection, and metrology applications. It delivers a maximum measurement range of 0.03 inches with a dial graduation and accuracy of 0.0005 inches, making it suitable for close-tolerance setups on machine tools, surface plates, and inspection fixtures. The 40 mm white dial features a 0-15-0 reading scale and a glare-free, scratch-resistant crystal for clear readability under shop lighting. A carbide-tipped contact point and O-ring seal construction help the instrument hold up in typical production and toolroom environments. Licensed machinists, quality technicians, and precision-trade professionals are the primary users.

The 513-452-10T suits vertical measurement setups where the contact arm approaches the workpiece from above or at a steep angle. It fits standard toolholders and indicator holders via its included metric holding bar, stem, and swivel clamp, making it adaptable to surface plate stands, CMM fixtures, and mill or lathe setups. The 19.90 mm contact point length and 0.079-inch ball diameter are appropriate for accessing recesses, bores, and flat reference surfaces. The no-clutch structure and automatic reversal mechanism reduce wear and simplify bidirectional scanning passes.

Key Features

• 0.03-inch maximum measurement range with 0-15-0 dial scale for direct bidirectional reading
• 0.0005-inch graduation and accuracy for high-precision close-tolerance inspection work
• Carbide-tipped contact point resists wear during repeated contact cycles
• O-ring seal and dust- and oil-proof construction for production shop environments
• No-clutch structure with automatic reversal reduces mechanical wear over service life
• Glare-free, scratch-resistant, high-impact crystal for consistent dial visibility
• Includes two contact points, metric holding bar, stem, and swivel clamp

Compatibility

Designed as an OEM-style replacement or direct-use dial test indicator compatible with standard indicator holders, swivel clamps, and dovetail-style mounting accessories commonly used with Mitutoyo Series 513 indicators.

Installation Notes

Installation is performed by metrology technicians, machinists, or quality professionals using standard indicator holders and clamping accessories. Secure the stem or holding bar firmly in the clamp before taking measurements to prevent indicator movement that would affect readings. Ensure the contact point angle and contact force are appropriate for the workpiece material to avoid false readings or surface damage. Calibrate against a known reference standard before use in critical inspection operations.
