Detailed Description
The three-point measuring arrangement is intended for internal diameter measurement across the listed bore ranges. Each micrometer has a chrome-plated finish, a 90 mm measuring depth, carbide measuring faces and a metal ratchet mechanism for controlled measuring force. The construction references DIN 40050 / IEC 529.
Included accessories are a neutral English instruction manual, two silver wrenches, one silver hex key, one 150 mm extension rod and one 25 mm setting ring. Customer branding and serial-number marking are supported on the micrometer thimble. Each tool is packed in a plastic bag inside an aluminium case, protected by a bubble bag and placed in a natural-colour outer carton with a side shipping label.

Selection Advice
Select the model whose measuring range fully contains the target bore diameter. Adjacent sizes overlap at several transition points, including 16 mm, 20 mm, 25 mm, 30 mm, 40 mm and 50 mm, while the listed 50–63 mm and 62–75 mm models overlap from 62 mm to 63 mm and the 75–88 mm and 87–100 mm models overlap from 87 mm to 88 mm. Accuracy and resolution are not specified, so confirm these performance requirements before ordering when they are critical to the application.
