Mitutoyo 12AAB407 Deep Groove Stylus Surface Roughness

Product Description

The MITUTOYO 12AAB407 is a deep groove stylus designed as a replacement accessory for surface roughness testers. The stylus is the contact element that traces a workpiece surface, converting micro-level texture variations into measurable data for roughness analysis. Deep groove geometry allows the tip to reach into narrow channels, slots, and recessed features where a standard stylus cannot maintain consistent contact. Licensed metrology technicians, quality control inspectors, and precision machining professionals rely on this type of stylus to extend the utility of their surface roughness instruments in demanding measurement applications.

This stylus is used with surface roughness testers in metrology labs, machine shops, and quality assurance environments. It is suited for inspecting surfaces with deep or narrow profiles that require a specialized tip geometry to achieve accurate trace results. Applications include checking ground, honed, or milled surfaces in aerospace, automotive, and general manufacturing contexts where surface finish specifications are critical to part acceptance.

Key Features

• Deep groove geometry enables measurement in narrow slots, channels, and recessed surface features
• Designed as a direct replacement accessory for compatible MITUTOYO surface roughness testers
• Sold as a single unit, allowing targeted replacement without unnecessary inventory surplus
• UNSPSC Code 41114500 for streamlined procurement and catalog classification

Compatibility

Designed for use with MITUTOYO surface roughness testers. Verify stylus mounting interface and probe arm compatibility with your specific instrument model before installation.

Installation Notes

Stylus replacement should be performed by a qualified metrology technician familiar with the instrument manufacturer's service procedures. Power down the surface roughness tester before removing or installing the stylus to prevent damage to the detector mechanism. Handle the stylus tip with care to avoid contact with hard surfaces, as tip damage will directly affect measurement accuracy. After installation, perform a calibration check using a certified roughness reference specimen before returning the instrument to service.
