BDS HM Core Drill Bit 20/35 mm Quick In (HKK-F020)

This BDS carbide-tipped core drill bit stands apart from conventional twist drills by removing a solid slug rather than pulverizing the entire hole into chips. That annular cutting principle means less material to cut, lower energy consumption, and a cleaner, faster bore in steel, stainless steel, and cast iron. The 20 mm cutting diameter and 35 mm cutting depth are matched to demanding industrial metalwork, while the Quick-In shank locks directly into BDS magnetic core drilling machines for rapid tool changes and repeatable accuracy.

Highlights

• Carbide-tipped cutting edge for extended tool life and high precision
• Quick-In shank for fast, secure mounting on BDS magnetic core drills
• Internal coolant supply keeps the cutting zone cool and clears slugs efficiently
• Produces a solid slug instead of chips, reducing waste and improving hole quality
• Optimized for steel, stainless steel, and cast iron

In daily use

On the shop floor, the HKK-F020 delivers consistent performance in structural steel, heavy equipment maintenance, and fabrication. The hollow design and internal coolant channels prevent heat buildup, so the carbide tip stays sharp longer even in tough alloys. Because the bit cuts only the circumference of the hole, feed pressure stays manageable, and the resulting bore has clean edges with minimal burring. The Quick-In interface eliminates the need for adapters or chuck keys, letting operators swap bits in seconds and keep production moving.
