BDS HSS VarioPLUS kernboor 20 mm snijdiameter, 30 mm snijdiepte, Weldon-schacht KBK-VP020

Drilling large holes in steel and other metals can be slow and imprecise with standard twist drills. The BDS HSS VarioPLUS annular cutter solves this by removing only a ring of material, leaving a solid core, which reduces cutting time and extends tool life. This 20 mm cutter with a 30 mm cutting depth is engineered for magnetic core drilling machines and delivers clean, accurate holes in a variety of metals.

Who is it for

This annular cutter is ideal for metalworking professionals, fabricators, and maintenance technicians who need to drill precise, large-diameter holes in steel, stainless steel, cast iron, and non-ferrous metals. It is suited for use with magnetic core drilling machines in workshops, construction sites, and industrial settings.

Main features

• High-speed steel (HSS) construction for durability and heat resistance.
• Multi-cut geometry with 4 cutting edges for efficient chip removal and smooth cutting.
• Weldon shank (19.05 mm / 3/4 inch) for secure mounting in magnetic drills.
• Internal coolant supply for optimal cooling and lubrication during cutting.
• Uncoated surface for versatility across different materials.
