Big ACCU Stand Mag Base AMM-M

Description

Arriving late September 2025 for delivery – Pre-order now

The BIG Accu Stand AMM-M (Mini-Mini, Short Arm) is a compact precision magnetic base stand designed for dial test indicators. Made in Japan by BIG Daishowa, it delivers strong rigidity in a very small format, making it ideal for close-in inspection setups and tight workspace conditions.

This stand measures 125 mm in overall height from the base to the top of the arm when fully extended. It uses a dovetail mount for indicator attachment (not a standard Ø8 mm stem clamp) and includes a fine adjustment knob for precise positioning. Offered in used condition, it shows cosmetic wear from previous use but remains fully functional.
