Broca de corona BDS HSSVarioPLUS 21 mm con vástago Weldon, 55 mm de profundidad de corte KBL-VP021

Precision-ground HSS-VarioPLUS annular cutter delivers a 21.0 mm bore with a 55 mm cutting depth in a single pass. The Weldon 19 mm shank ensures rigid, vibration-free mounting on magnetic core drilling machines, while the optimized multi-flute geometry clears chips fast for clean, burr-free holes in steel, stainless steel, and non-ferrous metals.

Overview

The BDS KBL-VP021 is a professional-grade core drill engineered for high-volume metalworking. Its bright finish reduces friction and resists corrosion, and the cutter is compatible with both internal and external coolant supply to keep the cutting edge cool during extended runs. The HSS-VarioPLUS steel construction balances hardness and toughness, resisting edge chipping even in tough alloys.
