12 mm x 25 mm annular cutter
The Unibor MMS12 is a metric HSS annular cutter sized at 12 mm diameter by 25 mm length. It is designed for magnetic drill users who need an economical tool for softer metals and most mild steels. The cutter provides a 1 inch depth of cut for through-hole applications.
Capacity and cutting limits
The 12 mm diameter suits holes of that exact size in mild steel and softer alloys. Cutting depth is limited to 1 inch, so thicker workpieces will require multiple passes or a different tool. Hardened or abrasive materials will wear the high-speed steel teeth quickly and are outside the intended range.
HSS material constraints
High-speed steel construction keeps the cost low but limits heat resistance compared to carbide alternatives. Continuous heavy feed rates or dry cutting in tough steel will dull the edges faster. The cutter performs best with proper coolant and moderate speeds on the materials specified.

Questions about this item
Will the 12 mm shank fit the chuck on my existing magnetic drill?
The 12 mm shank matches standard magnetic-drill chucks that accept 12 mm shanks; verify your chuck specification before use.
How can I confirm the cutter is performing correctly after installation?
A clean, round hole at the full 25 mm depth in mild steel with steady feed and minimal burr shows the cutter is working as intended.
Does the package include pilot pins or coolant, or must I buy them separately?
Only the annular cutter is supplied; pilot pins and cutting fluid are sold separately.
