Spi MS160712033 Magnetic Indicator Base with on Off Switch

Product Description

The SPI MS160712033 is a magnetic indicator base designed to hold dial indicators, test indicators, and similar precision measuring instruments during inspection and layout work. The base uses a strong 80 kg magnetic pull to lock onto ferrous surfaces, providing a stable platform for accurate readings. An integrated on/off switch allows the technician to energize or release the magnetic hold without disturbing the setup. This type of base is standard equipment in machine shops, fabrication facilities, and quality control environments where repeatable positioning is required.

The MS160712033 is suited for use on surface plates, machine beds, lathe beds, milling tables, and other ferrous workholding or inspection surfaces. The adjustable arm and post configuration supports a wide range of indicator positioning needs. The post extends 6.5 inches and the rod reaches 7.99 inches, allowing reach into tight or offset measurement locations. Machinists, toolmakers, and quality technicians typically deploy this base for runout checks, surface comparisons, and part alignment.

Key Features

• 80 kg magnetic pull for secure hold on ferrous surfaces
• On/off switch allows quick magnet engagement and release without disturbing the setup
• Post height of 6.5 inches with 7.99-inch rod length for extended reach
• Mounting stem diameter of 0.38 inches accommodates standard indicator shanks
• Compact base footprint: 2.36 inches long by 2 inches wide by 2.16 inches tall
• Weighs 3.5 pounds for stable low-center-of-gravity positioning

Compatibility

Designed as a standard magnetic indicator base for use with dial indicators and test indicators that accept a 0.38-inch mounting stem diameter, suitable for general metrology and inspection setups on ferrous surfaces.

Installation Notes

Ensure the mounting surface is clean, flat, and free of chips or coolant before engaging the magnet, as debris under the base will reduce holding force and introduce measurement error. Cycle the on/off switch to the off position before repositioning the base. Verify the indicator clamp and all articulating joints are snug before taking readings. This tool does not require electrical connection or compressed air and involves no power-down procedures beyond standard shop safety practices.
