Purpose and user
The Unibor 27118 is a tungsten carbide tipped annular cutter with an integrated pilot designed for drilling structural steel. Its 3/4 inch universal shank allows it to fit magnetic drills and press systems from any manufacturer, making it a versatile choice for maintenance teams and metal fabrication shops.
Replaces and upgrade point
This cutter replaces worn or damaged high speed steel annular cutters when longer tool life and cleaner holes in tough alloys are required. The carbide tips maintain sharpness through repeated cuts in truck frames and heavy plate, so the switch pays off when downtime for bit changes slows a project.
Practical limits
The cutter achieves a maximum 1 inch depth of cut, so material thicker than that needs a different approach or multiple passes. The 3/4 inch shank diameter sets the minimum chuck capacity, and the carbide geometry is optimised for steel rather than non ferrous metals or wood.

Questions about this item
Will the 3/4 universal shank fit my magnetic drill press?
The 3/4 universal shank fits all brands of magnetic drill presses that accept a 3/4 inch shank.
How do I install the cutter and pilot, and what step is often missed?
Insert the pilot into the cutter first, then secure the assembly in the drill chuck; users often forget to seat the pilot fully before tightening.
When should I replace the tungsten carbide tips on this annular cutter?
Replace the cutter when the tungsten carbide tips show visible chipping, dull edges, or when cutting 1.3 inch depth steel becomes slow and produces excessive heat.
