BDS HSS standaard kernboor 40 mm snijdiameter, 30 mm snijdiepte, Weldon-schacht (KBK-040)

Drilling large-diameter holes in steel and other metals with a standard twist drill is slow, imprecise, and hard on your equipment. The BDS HSS Standard Annular Cutter (KBK-040) solves this by cutting only the periphery of the hole, leaving a solid core. This core drilling method requires less power, produces cleaner holes, and dramatically speeds up the job compared to conventional drilling.

Who is it for

This annular cutter is built for professionals who use magnetic drilling machines in steel construction, metal fabrication, plant maintenance, and similar industrial applications. It is ideal for creating through-holes in plates, beams, and pipes where precision and speed are critical. If you need a reliable 40 mm cutter for a Weldon 19 mm arbor, this tool fits the bill.

Main features

• High-speed steel (HSS) construction for durability and heat resistance.
• 40 mm cutting diameter and 30 mm cutting depth for standard plate work.
• Weldon shank with 19 mm (3/4 inch) diameter for secure mounting on magnetic drills.
• Four-flute design for efficient chip evacuation and smooth cutting.
• Bright (uncoated) finish, manufactured to DIN 845 standards.
• Versatile: suitable for steel, cast iron, non-ferrous metals, and plastics.

Tips

For best results, use a suitable cutting fluid or coolant to extend tool life and improve hole quality. Ensure the cutter is properly seated in the Weldon arbor and the workpiece is securely clamped. Apply steady, moderate feed pressure—let the tool do the work. After use, clean the cutter and store it in a dry place to prevent corrosion.
