BDS HSS Standard Annular Cutter 12.0 mm Cutting Diameter, 30 mm Cutting Depth, Weldon Shank (KBK-012)

For professionals who demand clean, accurate holes in structural steel and plate, the BDS KBK-012 annular cutter delivers a 12.0 mm diameter with a 30 mm cutting depth. Its HSS body is ground from solid for concentricity and long service life, while the Weldon shank ensures a secure, vibration-free fit in magnetic drilling machines. This is a general-purpose core drill that removes a solid slug instead of chipping away the entire hole, saving time and extending machine life.

Highlights

• High-speed steel (HSS) construction for durability and heat resistance
• 12.0 mm cutting diameter; 30 mm cutting depth
• Weldon shank (19 mm / 3/4 inch) for positive drive in magnetic drills
• Multi-flute design for efficient chip evacuation and smoother cutting
• Bright, uncoated finish reduces friction and is easy to inspect
• Ground from solid for precise geometry and repeatable results

In daily use

Mount the KBK-012 into any standard Weldon-compatible magnetic drill, apply cutting fluid, and let the tool do the work. The annular cutter removes a 12 mm core, leaving a clean bore with minimal burr. It performs well in steel, stainless steel, cast iron, and non-ferrous metals, making it a versatile choice for fabrication, maintenance, and construction tasks. The 30 mm depth covers most plate and profile thicknesses encountered on site or in the workshop.
