The BDS HSSVarioPLUS annular cutter with 21 mm cutting diameter and 30 mm cutting depth is engineered for efficient core drilling in metal. Its high-speed steel construction and Weldon shank make it a reliable choice for magnetic drilling machines and pillar drills, delivering clean, precise holes with minimal effort.

Highlights

• 21 mm cutting diameter for standard hole sizes
• 30 mm cutting depth for through-hole drilling in plates and profiles
• Weldon shank (19 mm) for secure mounting and optimal torque transfer
• HSS (High-Speed Steel) body for durability and heat resistance
• Supports internal and external cooling for extended tool life
• Bright finish reduces friction and improves chip evacuation

In daily use

Designed for steel, structural steel, and non-ferrous metals, this cutter produces a clean slug with minimal burring. The Weldon shank ensures quick tool changes and reliable centering, while the bright finish helps prevent chip welding. An ejector pin is required for slug removal, and the cutter can be used with magnetic drills or conventional machines with a suitable adapter.
