Tungsten carbide cutter for steel
The Unibor 27120 is a tungsten carbide tipped annular cutter with a 5/8 inch by 1.3/8 inch profile and a 3/4 inch universal shank. It is designed for drilling steel, including heavy sections such as truck frames. The tool is sold new and ready for workshop or field use.
3/4 universal shank fits all brands
The 3/4 inch universal shank allows the cutter to be used with magnetic drills and pneumatic machines from different manufacturers without an adapter. This compatibility reduces setup time when switching between equipment. The pilot is included to help start the cut accurately.
1 inch depth of cut limits thickness
The cutter provides a maximum depth of cut of 1 inch, so material thicker than that requires a different tool or multiple passes. Tungsten carbide tips resist wear in steel but are not intended for non-ferrous metals or hardened plate beyond the cutter's rating. Buyers needing deeper holes or different diameters must select another model.

Questions about this item
When will the tungsten carbide tips on the Unibor 27120 need replacing?
Replace the cutter when the carbide tips dull enough to slow the feed rate or leave a rough hole edge; lifespan varies with steel hardness and cutting speed.
What limits continuous cutting with this 1.3-inch diameter annular cutter?
Chip evacuation and heat buildup in the 1-inch depth of cut become the practical limits during prolonged drilling.
Does the 3/4 universal shank run hot when the cutter is used all day?
The shank itself stays cool; heat concentrates in the carbide tips and the workpiece, so cutting fluid is recommended for extended sessions.
