Mitutoyo 103011 Ball Contact Point Carbide 513 Series

Product Description

The MITUTOYO 103011 is a replacement ball contact point designed for use with dial test indicators. The contact tip is made from carbide, delivering consistent hardness and wear resistance under repeated measurement cycles. The contact point length is 0.74 inches, and the ball tip diameter is 2.00 mm. This type of contact point is a consumable accessory installed by machinists, metrologists, and precision measurement technicians working in shops, inspection rooms, and field calibration environments.

The 103011 is intended for use with Mitutoyo 513 Series Dial Test Indicators. It is a direct-fit accessory for precision measurement applications where accurate surface contact geometry is critical. Common install scenarios include CMM setups, surface plate inspection work, bore gauging, and runout checks on lathes and mills. The carbide material makes it well-suited for repeated contact with hardened steel and abrasive workpiece surfaces.

Installation Notes

Contact point replacement is typically performed by a machinist or metrology technician. Before replacing the contact point, remove the indicator from service and ensure it is secure in a holder or clamp. Use the appropriate spanner wrench or contact point tool to avoid damaging the indicator spindle threads. Do not overtighten the contact point, as excess torque can affect indicator accuracy or damage the spindle.
