Mitutoyo 900173 Carbide Height Gage Scriber

Product Description

The MITUTOYO 900173 is a carbide scriber designed for use with Digimatic height gages. It serves as a replacement or spare scribing attachment that mounts to the scriber carrier of a height gage, allowing machinists and quality technicians to mark workpiece surfaces or perform layout work with precision. Carbide construction provides hardness and wear resistance well beyond standard steel scribers, maintaining a sharp point through repeated contact with hardened workpiece surfaces. This part is sold individually and is suited for metrology and inspection environments where consistent scribing performance is required.

This scriber is intended for use with Mitutoyo 570 Series Digimatic Height Gages, specifically models 570-227 and 570-244. It is a common consumable in machine shops, inspection rooms, and toolrooms where height gages are used for surface plate layout and dimensional verification. Replacement is typically needed when the carbide tip shows signs of wear, chipping, or breakage.

Key Features

• Carbide material construction for extended tip life and hardness
• Designed as a direct-fit accessory for the 570 Series Digimatic Height Gage scriber carrier

Compatibility

Designed for use with Mitutoyo 570 Series Digimatic Height Gages, including models 570-227 and 570-244.

Installation Notes

Installation is performed by a machinist or metrology technician. Before replacing the scriber, ensure the height gage is powered down and placed on a stable surface plate or bench. Secure the scriber into the carrier using the appropriate clamping screw — do not overtighten, as carbide is brittle and can chip under excessive clamping force. Verify alignment and tip condition before returning the gage to service.
