CHOOSE THE TOOL FOR YOUR WORK
A modular circular system with a version choice to confirm
This WUTA system is a different choice from a fixed diamond chisel because the listing describes two interchangeable circular modes. It distinguishes a circular-chisel mode from a punch mode intended to leave a larger opening. The selected configuration is labeled 2G 3.38 mm-(2+9), identifying the listed size and tooth-group selection rather than a nine-tool kit.
The steel is identified as 4Cr13 stainless with black electroplating. The seller says second-generation circular heads have been replaced with third-generation heads, describes third-generation holes as 1–1.3 mm and warns that two kinds of circular heads ship at random. The 3.38 mm configuration label should not be used as the opening diameter; the listing does not define its measuring convention. The version name also does not guarantee one particular current head design.
The exact allocation of bodies, installed heads and loose replacement parts is not itemized in the text. Confirm that contents list before buying specifically for interchangeable modes or refills. Compare the Weaver set for a fixed 4 mm diamond profile, or the WUTA French pair for a fixed slanted profile. Those alternatives simplify the hole-profile choice but do not supply compatible replacement heads for this system.

What to check before choosing
Confirm the current head type
Check which supplied head version you will receive if a particular opening is essential.
Separate the size label from the hole diameter
3.38 mm is the selected configuration label; its measuring convention is not defined in this listing. The separate 1–1.3 mm statement concerns certain third-generation circular openings.
Your questions about this product
Does 3.38 mm describe the hole diameter?
The listing does not establish 3.38 mm as the finished hole diameter or define the label’s measuring convention. It separately gives 1–1.3 mm for third-generation circular holes, with a notice that two head types may ship randomly.
Will I definitely receive second-generation heads?
No. The seller says those heads were replaced with third-generation heads and that two types may ship randomly.
Is the 2+9 label a count of tools?
No. It identifies the selected tooth-group configuration. Exact body/head/spare allocation is not itemized.
