Unibor MMS25 annular cutter

The Unibor MMS25 is a metric HSS annular cutter sized 25mm x 25mm. It is designed for magnetic-base drilling in softer metals and most mild steels. The cutter provides a 1 inch depth of cut for through-hole work. This accessory suits workshops that need an economical metric tool for repetitive drilling tasks.

Metalworkers needing 25mm holes

Fabricators who regularly produce 25mm diameter holes in mild steel plate will find this cutter matches their requirement. It is not intended for hardened alloys, stainless grades or abrasive materials that demand cobalt or carbide tooling. Buyers who need larger diameters or deeper cutting capacity should look at other sizes in the range.

Sustained cutting in mild steel

Under continuous feed the high-speed steel teeth maintain a steady chip load without the rapid dulling seen in short bursts. Heat builds gradually so cutting fluid remains effective throughout the full depth. The cutter ejects the slug cleanly at the end of each stroke, ready for the next hole.
