Mitutoyo 12AAB413 Deep Hole Stylus 2X-Long for SJ-400 Surface Roughness Tester

The Mitutoyo 12AAB413 is a specialized deep hole stylus designed for extended-reach surface roughness measurements with the SJ-400 portable surface roughness tester. This 2X-long stylus features a precision 0.005mm (5μm) diamond tip radius, enabling accurate roughness analysis in recessed areas, deep bores, and hard-to-reach surfaces where standard-length styli cannot access.

Key Features:

• Extended 2X-long probe length for deep hole and recessed surface measurement
• 0.005mm (5 micrometer) diamond tip radius for precise surface texture analysis
• Direct compatibility with Mitutoyo SJ-400 series surface roughness testers
• High-precision construction maintains measurement accuracy in confined spaces
• Optional accessory for expanding SJ-400 measurement capabilities

This optional stylus attachment is essential for quality control professionals and inspectors who need to verify surface finish in challenging geometries such as cylinder bores, deep cavities, narrow slots, and other inaccessible areas where standard probe configurations are limited.
