The MITUTOYO 64HAA101 is a diamond Rockwell indenter designed for superficial hardness testing applications. With an overall diameter of 3/8 inches and an overall height of 0.906 inches, this indenter is precision-machined to deliver consistent, repeatable results during Rockwell N scale hardness testing procedures. The diamond tip provides the hardness and wear resistance required for accurate indentation into metals and alloys. It is installed and serviced by calibration technicians and quality control professionals working with Rockwell hardness testers in laboratory and manufacturing environments.
This indenter is intended for use in Rockwell superficial hardness testing setups where the N scale is required. It fits specific Mitutoyo hardness testing machines listed below. The part ships as a single-piece replacement component, making it suitable for routine maintenance and calibration upkeep of existing testers. Typical install environments include metallurgical labs, production quality control stations, and tool-and-die shops where surface hardness verification is part of standard workflow.
Compatible with the AR-20, ARK-600/601, and ATK-600/601 Rockwell Superficial Hardness Testing Machines as specified by the manufacturer.
Installation should be performed by a qualified calibration technician or metrologist familiar with Rockwell hardness tester servicing procedures. Power down and isolate the tester from any load before removing or installing the indenter. Handle the diamond tip carefully to avoid chipping or contamination, as surface damage will affect test accuracy. Verify proper seating and perform a calibration verification using a certified test block before returning the instrument to service.
