Value Collection 6605-4050 Dial Drop Indicator 0.5 in

Product Description

The VALUE COLLECTION 6605-4050 is a dial drop indicator designed for precise linear measurement in machining, fabrication, and inspection applications. It features a 0.5 inch total measurement range with a graduation of 0.001 inches per division, allowing for accurate detection of surface variation, runout, and part alignment. The 2.281 inch diameter white dial face displays readings from 0 to 100, and a built-in revolution counter tracks full spindle cycles for measurements that span multiple revolutions. The lug back mount provides a standard attachment point for use with magnetic bases, surface plates, and indicator holders. This tool is installed and used by machinists, tool-and-die technicians, and precision measurement professionals.

The 6605-4050 suits general-purpose inspection work in job shops, maintenance environments, and quality control stations. It is appropriate for checking shaft runout, verifying flatness, setting up workpieces on milling and lathe setups, and confirming dimensional tolerance during part inspection. Its English unit graduation makes it compatible with standard inch-based inspection workflows common in North American manufacturing and trades environments.

Key Features

• 0.5 inch measurement range for short-travel linear inspection tasks
• 0.001 inch graduation for precise surface and runout readings
• 0-100 dial reading scale on a 2.281 inch white dial face
• Revolution counter tracks spindle travel across multiple cycles
• Lug back mount compatible with standard indicator holders and magnetic bases
• English unit (inch) measurement system

Compatibility

Designed as a standard lug back dial drop indicator compatible with common indicator holders, magnetic base arms, and surface plate setups used in inch-based precision measurement applications.

Installation Notes

Mount the indicator using the lug back attachment with a compatible holder or magnetic base arm, ensuring the spindle axis is perpendicular to the measured surface for accurate readings. Verify the indicator tip contacts the workpiece with light, consistent preload before zeroing the dial. Avoid side-loading the spindle, as lateral force can cause premature wear and inaccurate readings. No power source is required for this mechanical instrument.
