Mitutoyo 64PKA078B Dial Indicator Base Kit Magnetic

Product Description

The MITUTOYO 64PKA078B is a dial indicator base kit designed for precision measurement in machine shop, toolroom, and field service applications. The kit includes a magnetic base and a jeweled bearing dial indicator, providing a stable and repeatable setup for inspecting workpiece geometry, runout, flatness, and surface variation. The jeweled bearing construction reduces friction for smooth needle travel, and the magnetic base locks securely to ferrous machine surfaces. The indicator measures from 0.0000 to 0.0500 inches with a graduation of 0.0001 inches, making it suited to close-tolerance inspection work.

This kit is used in manufacturing, maintenance, and quality control environments where a fast, rigid indicator setup is required. The magnetic base attaches to mill tables, lathe beds, surface plates, and similar ferrous surfaces without clamps or fixtures. It is a two-piece set and is appropriate for machinists, tool-and-die technicians, and maintenance professionals who need a self-contained dial indicator solution ready for immediate use.

Key Features

• Jeweled bearing mechanism for low-friction, repeatable indicator needle movement
• Magnetic base style for tool-free attachment to ferrous surfaces
• Measurement range of 0.0000 to 0.0500 inches for close-tolerance inspection
• Graduation of 0.0001 inches for fine resolution readings
• Two-piece kit includes indicator and magnetic base for a complete setup
• Overall length of 10 inches for reach flexibility in typical setups

Compatibility

Designed as an OEM-style dial indicator base kit suitable for general precision measurement and inspection setups on ferrous machine surfaces.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with dial indicator setup procedures. Before mounting, ensure the magnetic base contact surface and the machine surface are clean and free of chips or coolant residue for maximum holding force. Engage the magnetic base lock fully before taking measurements, and verify the indicator spindle is perpendicular to the measured surface to avoid cosine error. Do not subject the indicator to shock loading or use it to measure surfaces in motion unless the unit is rated for dynamic measurement.
