Value Collection 6605-4080 Dial Drop Indicator 1 in

Product Description

The VALUE COLLECTION 6605-4080 is a dial drop indicator designed for precision dimensional measurement in machining, inspection, and alignment work. It delivers a 1 inch measuring range with 0.001 inch graduations on a 0-100 dial reading scale, allowing technicians to detect surface runout, shaft deflection, and part variation with reliable accuracy. The 2.28 inch diameter black dial face provides clear reading under shop-floor conditions. A built-in revolution counter tracks full-cycle travel so the user does not lose position during multi-pass measurements. The lug back mount allows quick fixture attachment on magnetic bases, surface plates, and inspection rigs commonly used in metalworking and mechanical trade environments.

This indicator suits residential and light commercial mechanical service, machine shop inspection, and field alignment tasks. Typical applications include checking shaft runout on motors and pumps, verifying flatness on machined surfaces, and setting tool height on lathes or mills. HVAC and plumbing technicians also use drop indicators when aligning pump flanges, checking motor shaft concentricity, or verifying component seating during equipment installation. The English unit scale makes it a direct fit for standard-dimensioned work in North American trade settings.

Key Features

• 1 inch measuring range with 0.001 inch graduation for precise dimensional checks
• 0-100 dial reading scale on a 2.28 inch diameter black dial face for easy readout
• Revolution counter tracks cumulative travel across the full range
• Lug back mounting style compatible with standard magnetic bases and inspection fixtures
• English unit calibration suitable for standard North American trade and shop use

Compatibility

Designed as a standard lug-back dial drop indicator compatible with magnetic base holders, surface gauge arms, and inspection fixtures that accept lug-style mounting stems common in general-purpose machining and mechanical trade applications.

Installation Notes

Installation is performed by machinists, millwrights, and mechanical service technicians. Secure the lug back firmly to the holder arm before taking any measurement to prevent indicator movement. Ensure the spindle axis is perpendicular to the measurement surface to avoid cosine error that skews readings. Do not exceed the stated measuring range or apply side loads to the spindle, as either can damage the internal gear train.
