MITUTOYO Extension Rod 125MM F/511 953549

This extension rod helps you with deep hole measurements, and offers the following benefits:

• Using a single, longer extension rod rather than several short ones reduces errors. When several extension rods are joined together, there is the possibility of minor errors arising from the additional joints involved. It is therefore good practice not to connect more than 2 rods to the drill gauge at one time.
• You can use extension rods up to 1000mm.
• If you are using extension rods longer than 500mm, use the bore gauge in a vertical orientation.
• You can confirm the accurate and satisfactory operation after connecting the extension rod.
