BDS KBK-030 HSS Annular Cutter 30 mm Cutting Diameter, 30 mm Cutting Depth, Weldon Shank

Precision core drilling in steel demands a cutter that stays sharp and true—the BDS KBK-030 delivers a 30 mm diameter hole with a 30 mm cutting depth, engineered from high-speed steel for clean, efficient cuts in structural steel, cast iron, and non-ferrous metals.

Overview

The BDS KBK-030 is a standard series annular cutter with a Weldon shank (19 mm / 3/4"), designed for magnetic drilling machines. Its four cutting edges ensure smooth chip evacuation and reduced cutting forces, while the uncoated HSS body provides reliable performance across a range of workshop applications. A pilot pin is required for centering and coolant flow.
