BDS HM Core Drill D25/35mm Quick In (HKK-F025) - Tungsten Carbide Tipped Annular Cutter

This BDS HM core drill stands out from typical twist drills by removing only a ring of material, leaving a solid slug that ejects cleanly. The result is a faster, smoother hole with far less power draw on your magnetic drilling machine. With a 25 mm cutting diameter and 35 mm depth, it is built for serious metalworking tasks where precision and repeatability matter.

Highlights

• Tungsten carbide tipped (TCT) cutting edges for exceptional wear resistance
• Quick-In shank for fast, tool-free bit changes on compatible BDS machines
• Three cutting edges distribute load evenly, reducing vibration and improving hole quality
• Optimized for steel, stainless steel, cast iron, and non-ferrous metals
• Hollow design allows efficient chip evacuation and internal cooling

In daily use

On the shop floor, this core drill delivers clean, burr-free holes in a single pass. The Quick-In system means you can swap between sizes in seconds without wrenches or collets. Because the carbide tips stay sharp longer than HSS, you spend less time replacing bits and more time drilling. The 35 mm depth is ideal for plates, beams, and profiles up to that thickness.
