The VALUE COLLECTION 852-4 is a replacement feeler accessory designed for use with Co-Ax indicators. The feeler serves as the contact element that transmits workpiece deflection to the indicator mechanism, making it a critical wear component in precision measurement setups. This part is used by machinists, toolmakers, and metrology technicians who rely on Co-Ax indicators for bore centering, runout checks, and alignment tasks on manual or CNC machine tools. At 0.06 pounds, it is a lightweight, single-unit replacement suitable for keeping a Co-Ax indicator in service without requiring full instrument replacement.
The 852-4 feeler is appropriate for workshop, tool room, and production floor environments where Co-Ax indicators are standard equipment. It is typically installed during routine maintenance or after feeler wear or damage affects measurement accuracy. This replacement supports precision measurement workflows in machining, grinding, and inspection applications where indicator reliability is required.
Designed for use with Co-Ax indicators. Verify feeler geometry and attachment method against your specific Co-Ax indicator model before installation.
Installation is typically performed by a machinist or metrology technician familiar with Co-Ax indicator disassembly. Remove the indicator from the spindle or holding fixture before replacing the feeler. Handle the feeler carefully to avoid bending or contaminating the contact surface, as deformation will affect measurement accuracy. Follow the instrument manufacturer's reassembly procedure to ensure proper feeler seating and repeatable readings.
